Automotive Sector in Malaysia

-September 2008’s TIV (total industry volume) released by the Malaysian Automotive
Association (MAA), showed a 12.8% increase YoY and 7.4% MoM to register at 50,729 units.
Passenger car (PC) sales increased 8% from the previous month but this was setoff by a 3%
decline in commercial vehicles. The encouraging sales of PC was attributable to heavy
promotional activities ahead of Hari Raya festivities.

-A point to note this time around is the fact that local carmakers gained market share at the
expense of non-nationals. Perodua’s and Proton’s market share increased to 30.9%
(+1.1pp) and 27.5% (+2.8pp) respectively, while Toyota, Honda and Nissan saw their market
share slip by 2.2pp 0.4pp and 1.1pp.

- Nissan, which posted a notable 11% MoM decline (for PC segment), saw its volume driving
models registering significant contraction in sales. The Sylphy, which has seen average
monthly volume of 340 units for the first three months since its launch, saw unit sales
dropping to 308 units (-30% MoM) for the month of September.

- Meanwhile, the Latio, which was launched mid last year registered a 26% drop MoM. Sales
volume dropped to only 219 units in September versus an average 347 units/month for the
first 8 months of 2008. In addition, the Livina saw volumes decline 12.4% compared to the
previous month.

- Perodua’s and Proton’s gain in market share was unsurprising, as car buyers would
naturally migrate down to more fuel efficient, lower capacity and affordable cars amid
inflationary pressures, depleting disposable income and rising hire purchase rates. Proton
registered a 19.7% MoM growth in sales, driven primarily by the Saga, which posted a 22%
MoM increase to 7,634 units. In addition, sales for its Persona model (Proton’s 2nd largest
volume driver) also registered healthy growth of 20% MoM.

- Perodua - which registered an 11.2% MoM growth - saw a 30% increase in sales of the MyVi,
but its Viva model saw a slight 3% decline. Our channel checks indicate a possibility of
Perodua coming out with a new model in 2009, while no indication on capacity and vehicle
class or price segment has been revealed at this juncture.

- Although Sept TIV bounced back compared to a YoY contraction posted in August, we
think this will be shortlived and the sector will see significant deterioration as the impact of
a slowing economy trickles down to the man on the street. We expect the fourth quarter to
see typical seasonal weakness on top of a more pronounced impact of slowing consumer

- Auto stocks under our coverage currently trade within a range of 7x (Tan Chong) and 11x
(UMW) FY09F earnings and 0.4x (Proton) to 1.7x (UMW) on FY09F book value. Despite
cheap valuations, we remain NEUTRAL on the auto sector given the lack of earnings
catalyst and muted demand visibility going forward, which would cause auto companies to
continue trading at depressed valuations. We retain our NEUTRAL rating on Tan Chong (TP:
RM1.58) and Proton (TP: RM3.02 and our BUY recommendation on UMW (TP: RM7.88).

A free trade agreement between Japan and Malaysia took effect Thursday July 13, 2006 , enabling the two countries to scrap tariffs on essentially all industrial goods and most agricultural, forestry and fishery products within 10 years.

To signify the launch of the FTA, the two nations held the same day their first joint committee meeting at the Japanese Foreign Ministry’s Iikura guesthouse in Tokyo to discuss operational procedures on the implementation of the FTA.

Japan was represented at the meeting by Economy, Trade and Industry Minister Toshihiro Nikai, Minister of Agriculture, Forestry and Fisheries Shoichi Nakagawa, Foreign Minister Taro Aso and Finance Minister Sadakazu Tanigaki. Malaysia’s delegation was led by International Trade and Industry Minister Rafidah Aziz.

Japan and Malaysia signed the bilateral FTA in December following nearly two years of negotiations. Malaysia is the third FTA partner for Japan following Singapore and Mexico.

The Japanese and Malaysian ministers issued a joint press statement to mark the FTA’s entry into force, which called the FTA a "solid basis for the strategic partnership between Japan and Malaysia."

The ministers from both nations "shared the view that the (FTA) will contribute toward enhancing the cross-border flow of goods, services and capital between Japan and Malaysia...enable both countries to make the most of their economic complementarity."

For example, Kuala Lumpur will remove tariffs on finished passenger cars with engine displacements above 2000 cc by 2010 and smaller vehicles by 2015. It will also immediately abolish tariffs for completely knocked down auto parts for Japanese carmakers assembling vehicles in Malaysia.

For farm products, Tokyo will immediately eliminate tariffs on Malaysian imports of tropical fruits like mangoes, mangosteens, durians, papayas and rambutans.

The accord will cover not only trade in goods, but also services trade, intellectual property right protection, investment rules, competition policies, business facilitation and cooperation projects for personnel training in Malaysia.

Japanese manufacturers would benefit from the FTA as it will boost their competitiveness by lowering parts procurement costs in Malaysia, while Malaysian local industries would also gain from Japan’s cooperation programs stipulated in the accord, according to Japanese officials.

Under the partnership, Japan will accept 1,000 trainees over the next 10 years from relevant Malaysian institutions for human resources development in such areas as agriculture, education and information technology. A total of 24 programs are set to be implemented immediately now that the pact has entered into force.

In 2005, Japan’s exports to Malaysia totaled $12.6 billion and imports from the country stood at $14.8 billion, according to the Japanese government.

KP Gasket Set Content

In KP brand gasket set, including Head Set and Full Set, their items content sometime may caught you by suprise, for example, the cam plug seal showed in the photo is KP Honda B20A Head Set is mostly not seen in other brands, and you will find it in lot of other model once you explore to it.
As KP gasket follow all the requirement in OEM standard, which they may have some item which had higher quality than the OEM gasket, as there are quite a lot of OEM spare parts are made in Thailand for Japanese car model, though KP Gasket pricing maybe at the high end, but their quality will speak for themself once you try it.

Toyota Levin 20 valve

The 20-Valve 4AGE replaced the 4AGZE Supercharged engines. Just like the early and late 16 Valve 4Ges, they also underwent revisions. The Silver Top was introduced in the Corolla AE101 (1992), and the Black Top in the Corolla AE111 (1997). Both engines used Toyota�s version of Variable cam timing- VVT.
Bore and stroke remained as in the original 1st and 2nd Generation 4AGEs (early) big port (TVIS) and (late) small port (non-TVIS). Similarly compression was upped in the later models. The blocks are identical to the late model AE92 generation blocks (and naturally the SC blocks too). MODIFYING THE 4AG / 4AGZE Block: The 4AG block is a free revving and strong bottom end. A stock block will survive in excess of 350 HP if air-charged in the 8000 RPM range, or 250 HP in the 10000RPM range.
The 2nd generation blocks with oil squirters should be the minimum considered. The connecting rods are also beefier, similar to the 4AGZ. The 1st generation block had smaller wrist pins and rod journals, which should be fine for milder tunes. For serious competition the rods should be replaced. Stroking the crankshaft to a maximum 81mm will keep the RPM capability intact. Bores can be brought out to 83mm, but try to keep it under 82.5mm.
There is no need for the Formula Atlantic crankshaft. Reject blocks that will need 83mm to clean up, for sure there is head damage also. Stay away from the 7AF to 7AG conversion since the crank is not forged and the flywheel bolts are too small, with no provision available to upgrade. The rods are potential failures also when subjected to real 4AG RPM operation. It is an exercise in creativity but a total sidestep for any real performance-oriented application.
If you like the torque of the 7AF, use the complete engine. Cylinder Head: There are some issues about the Formula Atlantic head. The Formula Atlantic head is a modified 4AG head- port and polished with the valve adjusters changed to the under-the-bucket shim arrangement (similar to the 2TG and 18RG). The valves and springs are different too. This modification is required when running camshafts with high lift and/or long duration (above 300).
For street purposes there is no advantage converting to this adjustment method or preparing the head to Atlantic specifications. The port and chamber modifications will decrease performance- short of preparing the complete engine to Formula Atlantic specifications, which will render the package totally unstreetable. There is very minimal head preparation needed, aside from match porting and polishing the runners. Porting the heads on this 16 valve Twin Cam more often decreases the air velocity- resulting in poorer throttle response.
Despite others claim of a 20HP or more increase- on modified heads alone, this is simply impossible without camshaft or pistons changed. Toyota has casted and machined all their 4 valve heads to very close and accurate tolerances for street (and rally) use. Camshaft choices for stock EFI systems and pistons should be limited to less than 265 duration. Upgraded blocks with pistons of at least 10.5:1 compression may use up to 288. It is recommended to convert to under-the-bucket shims for durations over 300 (with corresponding higher compression pistons).
Installing high duration cams on the stock set-up will cause the shims to fall-off and instant result in instant engine seizure. As always stay away from reground cams with non-factory lobe centers, you will have problems getting the correct adjustment shims. On the 4AGZ intake manifold- the #1 runner, which is dog-legged, must be filled and recontoured. This is a simple procedure that must be done. Be sure to frequently check the supercharger oil also. Many units have died because of oil starvation. The 5 valve head is Toyota's bonus to the 4AG after the 4AGZE went away. With the additional valve and independent throttle bodies- the 4AG 20 valve is a unique head design. This head unfortunately has many proprietary pieces and the only way to do a conversion to a 5 valve is only with a complete engine. The distributor position may be a problem in RWD installations. (Note: There are 2 versions of the 5-valve engine, see related information under Japanese engines).
Supercharger / Turbo Upgrade- The preparation for the turbo set-up is to lower the compression. The 4AG / 4AGZ that will see boosts in excess of 10 psi should be set-up with forged pistons. Blocks with the oil squirters must be used as these come with the better rods. For boosts higher than 18 psi, the rods have to be replaced. Oil cooler is mandatory, and for all applications a bigger radiator is a good investment. Use the 4AGZ injectors and fuel pressure regulator for turbo conversions of the normally aspirated 4AG. 550cc injectors are available for serious boost / engine outputs. The fuel pump can be replaced with the Supra Turbo pump, a direct bolt-in. Fuel System- If at all possible avoid using the dual side-draft carbs. The cost for the carbs / manifold plus ignition conversion will come close to a new fuel injection system. The EFI system will be adequate for minor tuning. 4AG/Z EFI systems use either an AFM (air flow meter) or MAP (manifold air pressure).
The AFM model is actually preferred since it will allow the user some adjustability for modified cams; there is no compensation available with MAP sensors. There is no advantage to converting to a MAP sensor, the idea of loss HP due to the AFM restriction is not true. Ignition System: Even 4AGZs equipped with DFI (direct fire ignition), will see a performance increase with an ignition amplifier. This is one of very few Toyota ignitions that are marginal. Colder plugs must be used with any upgrade. For carburetor equipped 4AGs the distributor has to supplemented with a timing controller, MSD 6A, and a coil.
