i have a 92 toyota soarer with a 1jz-gte, i love the 1j and the 2j they both make reliable power 750hp is low on the scale of what either motor is able to do. I myself plan to have around 800 rwhp on factory bottom end, i will say if your looking for those numbers to get arp head studs and a mls head gasket is a must. a set of cams injectors a good fuel set up and a nice turbo will most def get those numbers.
