Stock Supra 1990 modification
 

Hi everyone, i have a stock supra 1990 turbo, automatic with 70k with the 7mgte and i want to know what is the maximun of horsepower i can put in the original engine without the risk of any damage, and what modification can i do and how many horsepower.:uh:

None! none at all.. in fact you should just sell me your car right now..

Just kidding. start by re torquing the head gasket to (damn I always forget,) 75? 80 lbs for stock bolts? then go ahead and just look in the faq, there's tons of topics and threads on this my friend, ill dig around and post a couple links and edit this post in a few. For starters just off my head, granted your motor is up to par internally (seals gaskets and the like.) upgrade your turbo or boost it to like 9-11 psi. upgrade your headers / downpipe / exhaust. and your at 300hp. congrats on the car and good luck.

ok, thank you very much
