Compressor Engine

There are some engine starting to use the turbine compressor engine just like turbo jet airplane instead of the conventional piston driven engine, like the Mazda RX7 and RX8 and also the compressor fleet from Mercedes-Benz, just find the video link on this post for on "How a jet engine work" which the theory is the same apply on the passenger car engine.

Nissan March and Mitsuoka MPV

Recent news on Nissan Japan had recall their vehicle due to some ignition problem that will stall the engine, which Edaran Tan Chong Motor Sdn. Bhd. had mention the Malaysia market Nissan Serena, Navara, Slphy and Latio is not effected on the recall except for the fully imported from Japan Nissan March Model.

Since I am personally quite like the Nissan March design, this article is just to share which model had been using the same engine on this new Nissan March, don't be surprise the answer is the Mitsuoka MPV which also use the same engine of CR14DE like Nissan March, and who can tell if another model of Mitsuoka model name Cute which design have some similarity with March, is using the same engine or not?

How SR20 Metal Cylinder Head Gasket Use in 2 type of engine

The left hand side is the metal cylinder head gasket, and the right hand side is the original cylinder head gasket for Nissan Silvia DOHC 2.0 for Model PS13 and S13 which carry engine code of SR20DT, every hole the provided in the original gasket is also appear in the metal type of gasket, even metal type of gasket have a few hole more which it actually not effect the original design on this gasket.

Same gasket on the left hand side for the metal type of gasket, but the right hand side is the original cylinder head gasket for Nissan Silvia DOHC 2.0 for Model S14 which carry engine code SR20DET, same as every hole that have on the original gasket is appear on the metal type of gasket.

How to Diffrentiate Gasket of SR20DET Engine

As Nissan SR20DET engine is not mean on the Malaysia local market, there are some confusion occur when owner who had modified the engine looking for the gasket.
First, the SR20 series is not stranger in Malaysia market, the Nissan Serena 2.0 C23 van is using the SR20DE engine, for those who modified from those engine with Turbo which they may call it Silvia, Primera or Pulsar (Skyline is actually more to the RB series engine which I am not include into here).

Here come the SR20DT and SR20DET differences in their gasket design, first the rocker cover gasket (photo shown as 13270), there are people mention it can be diffrentiate by the colour of the rocker cover which have red type and black type, actually the rocker cover is attached with "half moon' size of rubber which we just call it half moon seal (This term may not correct), and the 2 type of it is one of them attached with 3 pieces of this seal and another one is 4 pieces.

For the Spark Plug Seal (photo shown as 13270N), it is same design as the one with Serena 2.0 C23 but its rubber is thicker and the diameter is also bigger than the C23type.

The cylinder head gasket (phot shown as 11044) have the most variance of it, and the original material of this gasket actually is just graphite type but there are demand for the metal type of gasket. To make it easier for not making too much of confusion, there are one type of metal cylinder head gasket design as such it can be install on at least 3 type of difference SR20DET engine.

Nissan Leaf for Zero Emission

The Nissan Leaf (also formatted "LEAF" as bacronym for Leading, Environmentally friendly, Affordable, Family car) is a compact five-door hatchback electric car to be produced by Nissan. According to the manufacturer, the Leaf's all-electric range is 100 miles (160 km) in city driving.

Sales are scheduled to begin in the United States and Japan in December 2010, followed by Portugal in January 2011, Ireland in February, the United Kingdom in March, and the Netherlands in June, with global market availability planned for 2012. As the reservation process began for US customers, Nissan announced that availability for December 2010 is limited in quantities and to select markets and initially through online reservations only. The availability will be increased by the second quarter of 2011, with full US market rollout planned for 2012.

The announced price in Japan starts at ¥3.76 million, US$32,780 in the United States, GB£28,990 in the United Kingdom, and approximately €35,000 in the other three European countries where it will be launched first; these prices include the price of the battery package, and almost all countries have applicable tax incentives or subsidies.

Because the Leaf is an all-electric car, it has the advantages of producing no local air pollution, reduces the need to import oil and enhances energy security, and its total cost of ownership improves in comparison as the price of gasoline rises.

The Leaf expected all-electric range is 100 miles (160 km) on the EPA city driving cycle and remains the same as the EV-11 prototype. Based on third-party test drives, reviewers have found that the range available from a single charge can vary up to 40 percent in real-world situations; reports vary from about 62 miles (100 km) to almost 138 miles (222 km) depending on driving style, load, traffic conditions, weather (i.e. wind, atmospheric density) and accessory use.

Nissan tested the Leaf under several scenarios to estimate real-world range figures, obtaining a worst case scenario of 47 miles (76 km) and a best case scenario of 138 miles (222 km).

The Leaf uses a front-mounted electric motor driving the wheels, powered by a {{convert/{{{2}}}24kW·h0r=red=LoffAoffDbSoffs=}} lithium ion battery pack rated to deliver power up to 90 kW (120 hp). The pack contains air-cooled, stacked laminar battery cells with lithium manganate cathodes. The battery and control module together weigh 300 kg (660 lb) and the specific energy of the cells is 140 W·h/kg. It is estimated that each battery pack costs Nissan US$18,000 (as of March 2010[update]) and this cost is expected to be halved by mass production. The battery pack is expected to retain 70 to 80% of its capacity after 10 years; the battery pack's lifespan depends on how often (440-volt) fast charging is used and on environmental factors such as extreme hot weather, which is tough on the battery. Nissan states the battery will have a "lifespan of 5-10 years under normal use". In July 2010 Nissan announced that the Leaf's battery will be guaranteed for eight years or 100,000 miles (160,000 km). To keep the center of gravity as low as possible the battery is housed partly below the front seats, in a thin layer below the rear floor, and with the majority of the cells in a long rack below the rear seats. The pack does not intrude into the rear trunk space. The battery pack consists of 48 modules with each module containing 4 cells. The battery pack is assembled by Automotive Energy Supply Corporation (AESC) - a joint venture between Nissan, NEC and NEC Energy Devices. The battery's chemistry is LiMn2O4 (Lithium,Manganese,Oxygen).

Investment research on Auto sector in Malaysia

Festive dent; maintain OVERWEIGHT. Total industry volume (TIV) skid 21% mom
during the festive-shortened month of September. On yoy basis, TIV also slipped
6%, dragged down by weaker sales for Proton (-14% yoy) and Perodua (-13% yoy).
We should see a rebound in October as the number of working days normalise. We
maintain our OVERWEIGHT stance on the auto sector as major demand drivers
such as the economic outlook, consumer sentiment, the availability of credit and
new models are intact. On the cost front, a stronger ringgit against the greenback
and the Japanese government’s recent moves to control the rising yen are good
news for auto players. Factors that could catalyse the sector include 1) strong sales
performances, 2) a firming ringgit, and 3) more accommodative government
policies. Tan Chong remains our top pick in the sector.

• Maintain TIV growth projection of 10%. September sales brought YTD TIV to
453,249 units, up 14% yoy. Annualised YTD sales volume now stands at 604,332
units, 6% above MAA’s projection of 570,000 (+6% yoy) and 2% above our estimate
of 590,955 units. We are keeping our projection of 10% growth in TIV this year as
we expect the yoy sales growth to moderate in the remaining months given the
higher base of comparison. Also intact is our 5% TIV growth assumption for 2011.

• Nissan outpaced its Japanese peers. Although Nissan’s sales volume shrank 9%
mom, it did much better than its peers Toyota (-16% mom), Honda (-39% mom) and
also the industry (-21% mom). As a result, its market share rose by close to 1% pt to
6.6% in September. Toyota also gained 1% pt market share to 15.5%, mostly at the
expense of Honda. Perodua was one of the biggest losers during the month as its
market share slipped by more than 2% pts to 28.7%.

• Tan Chong stays our top pick. We are retaining our sales assumptions and
earnings projections for all the three auto stocks under coverage. Tan Chong
remains our preferred pick with an Outperform recommendation and a target price
of RM9.30. Backed by its expansion plans and stronger industry fundamentals, Tan
Chong boasts impressive earnings growth potential over the next three years, which
should support our EPS CAGR projection of 47%. We make no changes to our
Outperform call for UMW (TP: RM8.70) and Trading Buy recommendation for
Proton Holdings (TP: RM5.95).

O = Outperform, N = Neutral, U = Underperform, TB = Trading Buy and TS = Trading Sell

September vehicle sales
First yoy dip of the year. Total industry volume (TIV) in September contracted 21%
mom as September had fewer working days due to festivities and August was a
seasonally strong month. All vehicle segments recorded a mom drop in sales. On yoy
basis, TIV also slipped 6%, dragged down by weaker sales by Proton (-14% yoy) and
Perodua (-13% yoy). September sales brought YTD TIV to 453,249 units, up 14% yoy.
We should see a rebound in October when conditions normalise.

Market share movementsNissan gained share. Although Nissan’s sales volume shrank 9% mom (Figure 4), it
did much better than its peers Toyota (-16% mom), Honda (-39% mom), and the
industry (-21% mom). As a result, its market share rose by close to 1% pt to 6.6% in
September. Toyota also gained 1% pt market share to 15.5%, mostly at the expense
of Honda. Perodua was one of the biggest losers during the month as its market share
slipped by more than 2% pts to 28.7%

Transformation story; Tan Chong remains our top pick. Nissan’s annualised sales
volume stands at 35,088 units, 2% ahead of our projection of 34,500 units. Backed by
its expansion plans and stronger industry fundamentals, Tan Chong boasts
impressive earnings growth potential over the next three years, which should support
our EPS CAGR projection of 47%. Recently, it rounded off its Indochina strategy with
the proposed acquisition of 74% of Nissan Vietnam. With that, Tan Chong now has a
foothold in Laos, Cambodia and Vietnam. We maintain our Outperform
recommendation given the potential re-rating catalysts of 1) stronger earnings growth
trajectory, 2) new model pipeline, and 3) strategic positioning which will help it gain
market share and tap into regional demand. No changes are made to our earnings
projections and SOP-based target price of RM9.30.

ToyotaToyota’s September sales declined 16% mom to 6,754 units as sales fell across the
board except for Toyota Rush which recorded a 16% mom sales increase. Despite the
recent launch of the facelifted version, the Corolla Altis staged the weakest
performance in Toyota’s product line-up in September, with sales tumbling 35% mom.
The good news is Toyota’s 1% pt market share gain in September, which we think
was mostly at the expense of Honda.

UMW is an attractive laggard; maintain Outperform. Toyota’s annualised sales
volume of 89,720 units is largely within our projection of 91,000 units. Perodua’s
annualised sales volume of 188,148 units is also within our projection of 189,000
units. With 46% share of the domestic market through Perodua and Toyota, UMW is a
good proxy for the auto sector. However, its share price has risen only 6% YTD, well
behind the KLCI's 17% gain. We think that sentiment on the stock could be weighed
down by the losses at its O&G division. But we expect these losses to narrow in view
of WSP's improving performance and the commissioning of Naga 2. This, coupled
with improving auto earnings on the back of a strengthening ringgit and increasing
vehicle sales, should provide a basis for a re-rating. We reiterate our Outperform call
given the potential re-rating catalysts of 1) rising contribution from the auto segment,
2) recovery in its O&G earnings, and 3) listing of its O&G division. No changes are
made to our earnings projections and SOP-based target price of RM8.70, which
continues to tag target P/Es of 13.5x to its auto division, 10x to manufacturing &
equipment and 7.5x to O&G.

ProtonProton’s sales in September fell 20% mom. Sales of its core models (Persona, Saga,
and Exora) were 6-29% lower on a mom basis. Waja registered the steepest sales
decline of 52% as consumers waited for the official launch of its replacement, Proton
Inspira, in mid-November. Recall that the Inspira was open to bookings on 14 Oct.

Maintain Trading Buy for Proton. Proton’s annualised sales volume stands at
160,441 units, which is broadly within our projection of 159,000 units. We are
encouraged by management’s ongoing efforts to restructure the company. Apart from
the recent management restructuring of Lotus and the current push for its turnaround,
Proton is also embarking on initiatives which could help tackle the overcapacity, i.e.
the aggressive push for exports and plant consolidation. Fundamentally, Proton’s
improving financials are also encouraging. We maintain our Trading Buy
recommendation in view of the emergence of potential near-term catalysts such as 1)
new model launches, 2) ongoing restructuring of its internal operations, 3) more
[ 7 ]
inroads into export markets, and 4) renewed consolidation talks. Our target price
remains unchanged at RM5.95.

Toyota MR-2 Engine

Sometime customer did give just a little info when they wish to source for something which may turn out we give a different item.
A typical case for me is when customer just asking for Toyota MR-2 engine gasket.
As Toyota MR-2 is not the local model in Malaysia which in turn most of them are imported or had carry out engine modification, though Toyota MR-2 is known with their 3S series of engine, but it actually have slight chances on the gasket design depend on model to model.
We can provide a list of model of the MR-2 3S-GE or 3S-GTE engine but it is very hard to trace with model as sometime owner did change the engine to other model.
The basic list may as below,
1. Toyota 3S-GE MR-2 1998cc 1989-ON model SV20
2. Toyota 3S-GE MR-2 1998cc 1993-ON model ST20#, SW20
3. Toyota 3S-GE MR-2 1998cc 1997-2002 model ST12#, SW20, ST202, SXA10, SXA11
4. Toyota 3S-GTE MR-2 1998cc 1990-ON model SW20, ST165, ST185
5. Toyota 3S-GTE MR-2 1998cc 1993-ON model SW20, ST205

Toyota 2JZ-GTE Engine

The 2JZ-GTE is an inline-layout, six-cylinder, belt-driven dual-overhead camshaft, air-intercooled, twin-turbocharged, cast-iron block, aluminium cylinder headed engine designed and manufactured by Toyota Motor Corporation that was produced from 1991 until 2002 in Japan. Development and evolution of the engine was, principally, a response to Nissan's relatively new and then-successful RB26DETT engine which had achieved palpable success in FIA Group A and Group N touring car championships, worldwide. Final development of the 2JZ-GTE was outsourced to German engineering firm Johann A. Krause Maschinenfabrik GmbH for refinement to meet production car homogolation requirements set forth by the former All-Japan Grand Touring Car Championship.

For all applications, two gearboxes were mated to the engine:

Toyota A341E 4-speed automatic
Toyota V160 and V161 6-speed manual (jointly developed with Getrag as the Type 233)

The 2JZ-GTE originally powered the Toyota Aristo V (JZS147) in 1991 before becoming Toyota's flagship performance engine in the Toyota Supra RZ (JZA80). Its mechanical basis was the existing 2JZ-GE, but differed in its use of sequential twin turbochargers and an air-to-air side-mounted intercooler. The engine block, crank, and connecting rods of the 2JZ-GE and 2JZ-GTE are the same with the exception that the 2JZ-GTE has oil spray bars installed in the block to aid in cooling the pistons. Toyota's VVT-i variable valve timing technology was added to the engine beginning in September 1997, whence it phased out the original engine. Consequently, maximum torque and horsepower was raised for engines selling in all markets.

The addition of twin turbochargers, jointly developed by Toyota with Hitachi, in sequential configuration had raised its commercially-cited output from 230 PS (169 kW; 227 hp) to the, then, Japanese auto industry maximum of 280 PS (206 kW; 276 hp) at 5600 rpm. In its first appearance, torque was advertised as 44.3 kgm (435 Nm, 320 lbft) to be later recited as 54.1 kgm (530 Nm, 391 lbft) with the introduction VVT-i in 1997. The mutually-agreed, industry-wide output ceiling was enforced by Japan's now-defunct Gentlemen's Agreement, exclusively between Japanese automakers selling to the Japanese domestic market. For North American and European markets, power was raised to 415 PS (305 kW; 409 hp) at 5600 rpm.

The export version of the 2JZ-GTE achieved its higher power output with the use of newer stainless steel turbochargers (ceramic for Japanese models), revised camshafts, and larger injectors (550 cc/min for export, 440 cc/min for Japanese). The mechanical similarities between the Japanese-specification CT20 turbine and export-specification CT12B turbine allow interchangeability of the exhaust-side propeller shaft. Additionally, the export-exclusive CT12B turbine received more durable turbine housings and stainless steel turbine and impeller fins. Multiple variants of the Japanese CT20 turbine exist discretely, which are identified with the B, R, and A part number suffixes (eg.: CT20A).


Toyota Aristo JZS147 (Japan-only)
Toyota Aristo V300 JZS161 (Japan-only)
Toyota Supra RZ/Turbo JZA80

In around 2000, Toyota introduced what are probably the least recognised members of the JZ engine family – the FSE direct injection variants. These FSE 1JZ and 2JZ engines are aimed at achieving minimal emissions and fuel consumption together with no loss of performance.

The 2.5-litre 1JZ-FSE employs the same block as the conventional 1JZ-GE; everything up top, however, is unique. The ‘D4’ FSE employs a relatively narrow angle cylinder head with swirl control valves that serve to improve combustion efficiency. This is necessary to run at extremely lean air-fuel ratios around 20 to 40:1 at certain engine load and revs. Not surprisingly, fuel consumption is reduced by around 20 percent (when tested in the Japanese 10/15 urban mode).

Interestingly, normal unleaded fuel is enough to cope with the FSE’s 11:1 compression ratio.

The direct injection version of the 1JZ generates 147 kW (197HP) and 250Nm (184ft lbs) – virtually the same as the conventional VVT-i 1JZ-GE. This highly efficient engine is fitted to the 2000 Mark II, 2001 Brevis, Progres, Verossa, Crown and Crown Estate. All are fitted with an automatic transmission.

The 3-litre 2JZ-FSE uses the same direct injection principle as the smaller 1JZ version but runs an even higher 11.3:1 compression ratio. This engine matches the conventional VVT-i 2JZ-GE with 162 kW (217HP) and 294Nm (216ft lbs). The 2JZ-FSE is fitted to certain 1999 Crown models and the 2001 Brevis and Progres. Again, all use automatic transmissions

Honda Inspire 1st Generation to 5th Generation

On October 12, 1989, the "inspired Accord" was introduced. The Honda Inspire was shared with the Honda Vigor, which was a previous generation upper trim level JDM Honda Accord, and was later sold in the USA as the Acura Vigor. The Honda Inspire shared its platform with the flagship Honda Legend, which was co-developed with British Leyland and used for the Rover 800. The Inspire was introduced before the recession developed in Japan in the early 1990s, and Honda wanted a car that would compete with the Toyota Cresta and Nissan Laurel, with the unique inline 5 cylinder Honda G engine, in a front wheel drive configuration. The Inspire was very successful for Honda. This 5 cylinder engine was also used in the JDM Honda Rafaga, which was a sedan.

The bodystyle was a 4-door hardtop, but it wasn't a true hardtop, using a "B" pillar between the front and rear passenger compartments, but used frameless side doors.

The Inspire was offered before the recession took hold of Japan's economy during the early 1990s, and offered a luxurious approach to the interior. Interior appearance was provided by the Japanese furniture company, Tendo Mokko, offering unique leather interior and genuine wood inserts for the dashboard and center console. A choice of wood inserts were offered.

The SOHC 4 valve per cylinder G20A Straight-5 cylinder was all new, with a choice of 2.0 L or 2.5 L engine displacement. The five cylinder was a compromise between the smaller, frugal but weaker 4 cylinder engine, and the larger, less fuel efficient V6 engine, as Honda wanted the engine to be a good match for the Inspire's luxury aspirations. The harshness typical of a 5 cylinder engine was minimized by adding a counter rotating balance shaft and improved engine motor mounts. The engine produced adequate torque, which helped its fuel efficiency. The transmission is attached to the bottom of the engine, which allowed the powertrain to remain slightly behind the front wheels.

The vehicles offered by competitors were front engine and rear drive, which put the Inspire at a disadvantage with the weight of the powertrain being entirely over the front axle. The turning radius of the Inspire also was not as tight as its competitors, but the Inspire did have an advantage in adverse traction conditions.

The second generation Inspire was almost identical in its dimensions to the first generation Honda Legend, with that vehicle having been updated and enlarged to better fit the role of flagship for the Honda and Acura brands. The second generation Inspire was available with the Type I 3.2 L V6 offered in the Legend on July 6, 1995, while still offering the Straight 5 in both 2.0 L and 2.5 L versions. The profile of this vehicle was reduced somewhat to 1,405 mm (55.3 in). The luxury approach was enhanced.

The Inspire was also sold as the Honda Saber (Japanese: ホンダ・セイバー) and sold at the Honda Verno sales network, and mechanically identical to the UA1-UA3 Inspire

November 8, 1996 saw the introduction of dual airbags for front seat passengers and anti-lock brakes as standard.

As the recession in Japan began to take hold, cost cutting measures began to appear in the reduction in the quality of the interior. The interior approach began to take on a more family sedan friendly appearance, with influences from the Honda Odyssey.

This version of the Inspire competed with the Toyota Camry Gracia, Mark II, Cresta and Chaser, the Nissan Cefiro and Skyline, the Mazda Millenia and the Mitsubishi Diamante.

The third generation Honda Inspire/Saber was introduced October 15, 1998, and was the first Honda designed and built in the USA and imported to Japan. It was based on the CG series, USA-spec Honda Accord sedan, and closely related to the new Honda Torneo. Sales of the popular USA-spec Honda Accord began to be affected by the SUV growing in popularity, and Honda decided to send some of the Accords being produced in the USA to Japan.

The Inspire no longer offered the Straight-5 engine, and instead offered the 3.2 L J32A V6 and 2.5 L J25A V6 with VTEC, and a choice of a 4- or 5-speed automatic transmission. The bodystyle was changed from hardtop to sedan as a result of the USA-spec Accord having been upgraded to meet USA requirements for improved side impact protection.

The Honda Saber was discontinued April 2003 along with the consolidation of the Honda Japan sales network Primo, Clio and Verno.

The fifth generation Honda Inspire was released on December 19, 2007 in Japan, with a further increased enhancement to the vehicles dimensions, which are on par with the second generation Honda Legend. The Inspire is now one level below the fourth generation Honda Legend, with a comparable level of luxury and refinement of the Legend. The AWD system, called "SH-AWD" is not available on this iteration of the Inspire, however. Honda technologies such as "CMBS", Adaptive Cruise Control, called IHCC and HDD navigation equipment are included.

The Inspire now uses the base model V6 from the Legend. The power steering is now electric power assisted for better handling and response.

This vehicle is now being made available in Thailand and Southeast Asia, using the 2.0L, 2.4 L DOHC K24A and 3.5L with i-VTEC under the name Honda Accord. There are few exterior and interior differences between this Inspire and the USA-spec Honda Accord.

Nissan 370Z Photo

The photo is so beautiful that it should be to share with.

Almost every piece and component of the 370Z has been redesigned from the previous model (350Z). It is powered by the VQ37VHR 3.7 L (230 cu in) DOHC V6 with Variable Valve and Lift Control and produces 332 bhp (248 kW; 337 PS). Power delivery to the rear wheels comes through a new 7-speed automatic transmission with paddle shifters or 6-speed manual transmission which features the world's first synchronized down shift rev-matching system, SynchroRev Match. The SynchroRev Match system is only available with the sports package. The differential offered with the Sport Package is indicated to be a viscous limited slip differential.

Compared to the 350Z, the 370Z has a wheelbase 4 in (100 mm) shorter at 100.4 in (2,550 mm) and an overall length 2.7 in (69 mm) shorter at 167.1 in (4,240 mm). The overall width has been increased by 1.3 in (33 mm), the rear track by 2.2 in (56 mm), and overall height reduced by 0.3 in (7.6 mm). The smaller exterior dimensions and use of more lightweight materials help reduce weight. (Although it should be noted that a 2003-2005 base model 350Z is actually lighter in weight than the 370Z). The 370Z features a front aluminum subframe, aluminum-alloy engine cradle, aluminum door panels, an all-aluminum hood, and an aluminum hatch.

Front body torsion rigidity is improved by 10 percent with an extensively revised body structure which includes a new front suspension cradle to reduce front body lateral bending, new rear structural reinforcements, and an underbody "V-bar" to help reduce rear lateral bending. Additional enhancements include the use of a carbon fiber composite radiator housing and strengthening of the rear fender and hatch areas. Rear body torsion rigidity is improved by up to 22 percent and rear body vertical bending rigidity is improved by up to 30 percent. The new structure weighs slightly less than the 350Z.

The coefficient of drag is 0.30 and 0.29 with the Sport Package, figures identical to the 350Z.


When will this model will appear on the Malaysia road.

New Generation of Inlet Manifold Gasket

The intake (inlet) manifold form one of the important part of an engine, it is crucial to make sure there are no leakage between the joint of manifold surface and the engine block, which will effect the power and the fuel efficiency of the vehicle, so, the effectiveness of the manifold gasket can not be ignore.

Material of the intake manifold gasket also improve a lot, from the normal packing paper material or gasket sheet, it improve to a stage that using the thin layer of metal steel, but using the metal type of gasket need to ensure a very smooth surface on the manifold, so there are a lot of time it metal type of gasket is modified back to the paper sheet type of gasket.

Than the new generation of engine can be seen a lot of rubber type inlet manifold gasket, they will be a small groove to slot in the gasket, once had tell that the rational on changing the gasket to rubber type is because of environmental issue which will make less consume of gasket sheet which their original source is from trees.

When news come out that Proton will launch it new Inspira model on Nov 10, which it open the bookoing start from now, the long waiting Waja replacement at last give some idea on how the collaboration between Mitsubishi Motor Corp (MMC) and Proton made the Inspira looks like.

Before the news come out, the folk on street already talking about the Waja replacement will be using the body of new Mitsubishi Lancer and it seem it is no doubt about it, but I'm not really concern about it, what I'm interested in is straight go to find what engine it will use.

People are talking about Proton may only use the body of Lancer but modified it with their own Campro engine which use in their Gen2, Pesona, Exora and BLM range, but I' glad that I found some info under and shock about the 2.0 version will use the same range of 4B11 engine which is use on Lancer.

And when I already noted the 4B11 and 4B12 engine in the market, it is another fact that I found is the 1.8 engine is using 4B10 which this is new for me.

The Toyota Hilux 2KD-FTV engine full set gasket is one of those gasket set which come without the cylinder head gasket in it, I'm still thinking why they want to sell a overhaul set gasket without the cylinder head gasket, is it because the original cylinder head gasket is durable until the overhaul it still no need to change, or the cylinder head gasket actually have the 5 range of thickness so they want the owner to choose which thickness they want when they buy the set? Or it had other reason which I would like to have your opinion.

For the other type of engine that the Full Set Gasket didn't included the cylinder head gasket is like 14B-T, 15B-FT, 1KD, 1KZ-TE, 2L-T, 3L and 5L.Other than Toyota, the Nissan also have some model apply this concept like their engine of CD17, CD20, LD20T, LD28, QD32, RD28, TD23, TD25, TD27, TD42-T, YD25DDT and ZD30DDTI. Isuzu also have some engine range apply this concept such as 1988-on 4BE1, 4EC1, 4FG1 and 4HF1 (I think all the 4Hxx series also apply).


As stated in my earlier article which had mention this Mazda BT-50 model which the WE engine is manufactured in Thailand, which it turn to the OEM gasket part is supply from Thailand itself, it is wonder the Japan gasket manufacturer will produce this gasket or not, but in tern of costing the Japan part may cost higher than the OEM parts which is made in Thailand.

Ford Ranger or Mazda Fighter is among the popular truck in Malaysia, with the B2500 model which is come with 12 valve SOHC 2,499cc engine, with the Mazda engine code of WL, there are user mention that due to the cylinder head material, which the initial purpose is to make the engine more lighter, but due to the softer characteristic of the material, there are many cylinder head crack problem found for this engine, though it is from the amateur view, which I hope there are some professional comment on this.

Than it come the launch of new Ford Ranger TDC-i, which is come with 16 valve DOHC engine with Mazda engine code of WLC, though it is 2,500cc in Malaysia market, it is known that the engine is the same family with the one which Mazda produce in Thailand for the BT-50, which have the 3,000cc version with the Mazda engine code of WE.

Interestingly to know that the R&D for this engine is actually done in Thailand, other than the cylinder head gasket and some gasket which is similar with WL engine, the rocker cover gasket, intake and exhaust manifold gasket and other gasket that difference with WL engine, the OEM item may come from Thailand instead of Japan.

Than come with the GEMA engine which is the technologies from the joint venture of Chrsyler, Hyundai and Mitsubishi, the Sonata NF may have the engine code of G4KC and the Mitsubishi Lancer have the engine code of 4B11 or 4B12, should this engine is in the same family of design, it is possible that their rocker cover design will be the same.
