people say the 2jzge egnine (MK4 supra non turbo), that engine only can handle around 450HP or 500HP. but the 2jzgte egnine, the supra twin turbo engine can handle alot more HP. some people make 1000HP from the stock short block. so, a supra non-turbo is just like a 350Z. if you plan to get a supra non-turbo, i i would say just buy a 350Z, at least its a new car. and there are some new things.
