2JZ-GTE OR 2JZ-GE SERVICE MANUALS
2JZ-GTE Service Repair Manual:
The turbocharged 7MGTE was produced from 1988 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 7MGTEU 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. In fact, for 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 back yard 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.
