Workshop manuals, (one partial and one complete),
for the 7M-GE & 7M-GTE engines and ancillaries

NOTE: THIS IS ONLY THE ENGINE MANUAL.

The 7MGE are fitted to the following vehicles:

* 1986.5 1992 (19871993 in Japan) Toyota Supra MkIII (MA70)
* 1989 1992 Toyota Cressida Mark II (MX83)
* Toyota Chaser
* Toyota Crown
The Toyota 7M-GE introduced in the early months of 1986 is a 3.0 litre (2954 cc) 24-valve (4 valves per cylinder) DOHC/fuel injected engine. The valves are spaced at a performance-oriented 50° angle. Cylinder bore is 83 mm (3.27 in) and stroke is 91 mm (3.58 in).

The 7M-GE was produced from 1986 through 1992. Output was 190-204 hp (142-152 kW) at 6000 rpm and 185-196 ft·lbf (250-265 Nm) at 4800 rpm.

Not withstanding the technical sophistication and powerful output of the engine, it was plagued with the problem of regularly blowing head gaskets due to improper torque specifications of the head bolts from the factory. The 7M-GTE turbo version suffered from the same problem. Permanent fixes typically involved a metal after-market head gasket, higher torque settings (usually 70-80 ft·lbf) and upgrading to head studs (through the ubiquitous ARP and their hardware) rather than bolts.

Specifications:

* Displacement: 2954 cc (180.2 cu in)
* Bore: 83.00 mm (3.27 in)
* Stroke: 91.00 mm (3.58 in)
* Compression Ratio: 9.1:1
* Weight: 199 kg (440 lb)
=================================================
The 7MGTE engines are fitted to:

* 1988 > 1993 Toyota Supra MkIII (MA70)
* 1986 > 1991 Toyota Soarer (MZ20/MZ21)
The turbocharged 7M-GTE was produced from 1987 to 1993. Output was 232 hp (173 kW) at 5600 rpm and 240 ft·lb (325 N·m) at 4000 rpm for most 5 psi (0.34 bar) versions. It was Toyota’s top performance engine until it was replaced by the 2JZ-GTE.

A special 7M-GTEU version, with a modified CT26 high-flow turbocharger and large volume intercooler, pushed output to 267 hp (199 kW) at 5600 rpm and 264 ft·lb (358 N·m) at 4400 rpm. This was used only in the racing homologation Toyota Supra Turbo A road and race cars. The Turbo A models also measured air based on manifold pressure rather than using an air flow meter, had a larger intercooler, larger throttle body, optimized CT-26 turbo, and various other differences. During the short time it was produced, it was the fastest Japanese car ever made.

The 7M-GTE was known to suffer from blown head gaskets due to improper torque specifications of the head bolts from the factory. Despite endless claims to this problem and obvious proof of a design error, Toyota never took responsibility or issued a recall. This problem could easily be prevented by the backyard mechanic by removing the valve cover and re-torquing the head bolts to a higher torque specification. It is recommended to replace the head gasket and torque the head bolts to 75 lbs.

Specifications:

* Displacement: 2,954 cc (180.3 cu in)
* Bore: 83.0 mm (3.27 in)
* Stroke: 91.0 mm (3.58 in)
* Compression Ratio: 8.4:1
* Weight: 210 kg (463 lb)

SO IF YOU HAVE A TOYOTA AND IT HAS THESE ENGINES THEN YOU NEED THIS WORKSHOP MANUAL, TO KEEP YOU CAR RUNNING SWEET 😉
