I have a few questions about the early 90s Supra. 1) What is the displacement? 2) Is the engine strong? I know the newer Supra engine is pretty much bullet proof. 3) What size is the factory turbo? And can it be upgraded through different wheels or will a larger turbo fit the stock exhaust mani. Finally will the stock tranny (5spd) withstand larger amnts of hp?

Also what is the factory hp figures? Is it worth upgrading this model?

Thanks
Patrick
