Toyota Altezza SXE10 Top Set Gasket




































Toyota Altezza SXE10 which is using the 3S-GE engine, is the 5th generation and final version of the 3S-GE series of engine, it mention at Wikipedia site as below.

In 1998, the fifth and final version of the 3S-GE was released, found only in the Japanese-delivered Altezza RS200. The 'Black Top' as it came to be referred to as, was fitted with a dual VVT-i system that adjusted timing on both intake and exhaust camshafts and came in two different spec levels dependent on which transmission it was coupled to.
Gen 5 uses electronic controlled throttle with cable (semi-drive by wire), so no idle speed controller is required. A returnless fuel rail is also used.
The MT version that came equipped with the J160 6-speed manual transmission featured larger diameter titanium intake valves measuring 35mm, larger exhaust valves measuring 29.5mm also made from titanium, a larger 33mm bucket and a compression ratio of 11.5:1. It made 210 PS (154 kW; 207 hp) at 7,600 rpm and 22.0 kg⋅m (216 N⋅m) at 6,400 rpm.
Compared to the MT version, the 5-speed AT version came equipped with the A650E Tiptronic automatic transmission and had a lower compression ratio of 11.1:1, a less aggressive cam profile, smaller steel-alloy valves and smaller 31mm buckets. This engine made 200 PS (147 kW; 197 hp) at 7,000 rpm and 22.0 kg⋅m (216 N⋅m) at a considerably lower 4,800 rpm. Externally, the AT model can be identified by differences in the wiring loom and the lack of an acoustic blanket on the intake plenum.

It is also found in Toyota Caldina, MR 2, Celica, RAV 4 under ST12#, SW20, ST202, SXA10 and SXA11.

The cylinder head gasket having an extra small hole with the rocker cover gasket having a totally different design when compare to other 3S-GE model,  and the 2pcs of camshaft oil seal is come with 2 different size which is also different from other 3S-GE model of camshaft oil seal, don't know if it is to suit for the dual VVT-i design.
