this engine is black, it is referred to as the "Grey Top", taking its name from the grey intake plenum colouring. This naming is as such to differentiate it from the fifth-generation Dual-VVTi "Black Top" in the Altezza. Power output is at 6,600 rpm in the RAV4 and in the Caldina GT. The mechanical differences between the Red Top and Grey Top is the headers and the ECU. Wiring is identical. Casting provisions exist in the heads for Exhaust VVT solenoid, and RWD water gallery is open, behind the alternator mount. Rear oil drain at the back of the head is in a different position. Gen 4 also runs a manual throttle body. This engine was used in some TTE WRC Corollas (modified for Turbo). Generation 5 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 at 7,600 rpm and at 6,400 rpm. Compared to the MT version, the 5-speed AT version came equipped with the A650E 5Super ECT (with manual shift mode) 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 at 7,000 rpm and 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. Specifications 3S-GTE The 3S-GTE is an in-line 4-cylinder engine from Toyota, based on the 3S-GE with the addition of under piston oil squirters and a reduced compression ratio to accommodate the addition of a turbocharger. There are four generations of this engine, which started manufacture in 1986 and was built until 2007. The turbochargers used in the 3S-GTE engines are
