i have already converted my nt to turbo. its done. why can stock turbo cars run 12-17 psi and only around 10 for a converted.what does the turbo internals have that the non turbos dont.

thanks

Because your car was not designed wiht forced induction in mind. Things are different. Less fuel, weeker internals, stoiciametry biased ECU, and higher compression. If you were to change all these week points in previously N/A car, you would be able to turn the boost much higher.

OK, so you have stronger internals, you have more fuel(and a way to controll it), SO....... Who told you not to run more than 10psi??? Just between you and I, you can turn it up a bit more than that I do recommend logging it. Watch your knock, and youll be fine.

what is your compression with the wiseco's?

my dad wasnt sure (he is more of the muscle car guy and he wanted to see how 10 psi would do for 2 weeks) so thats why i m asking u guys

my wisecos are forged 9:1

Sounds like your motor's good for quite a bit more, but listen to what your dad says first. He'll be a lot closer than any of us if it grenades.... and he'll be a lot madder.
