okay here are my two questions. first what are the differences between NA and turbo supra automatic trannys. and second although the 2jz-gte and ge have different heads are the internals still the same size, not necessarily the same, for ex. if I wanted to buy oversized forged TT pistons put on my stock rods and crank and put in a ge block would it all work out? to be honest prolly not going to do this, just kinda curious.
