    7MGTE Motor

    the most common motor in the MKIII and the most underestimated motor in the supra family can make big power on a respectable budget and isn't hard to find good motor to put in a AE 86 if your trying to make big power but you don't want to pay the price of the 2jz here are some specs

    The turbocharged 7M-GTE was Toyota's top performance engine from 1987 through 1992. Output was 232 hp (173 kW) at 5600 rpm and 240 ft·lbf (325 Nm) at 4000 rpm for most 5 lbf/in²/0.35 bar versions.

    A special 7M-GTEu version, with a modified CT26 high-flow turbocharger and large volume intercooler, pushed output to 267 hp (199.1 kW) at 5600 rpm and 264 ft·lbf (357 Nm) 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.
