To4s

HOW MUCH BOOST DO I NEED TO RUN ON A TO4s to get 450 to the wheels WITH ALL THE MOD'S ON A STOCK MOTOR OR SHOULD I GO T78.

Are you referring to the T04S or T04's in general? From what I understand, the T04S and T78 turbos are very comparable. Making 450 HP will be more dependent on all your other mods...(manifold, exhaust, IC, tuning, etc...) On average I have been seeing anywhere from 400-425 hp at 15 psi. My guess is it would take about 18-20 psi to see 450 hp.

About how many miles do you think a stock motor will last given this setup? I'm thinking of replacing my motor with a stock motor. My current motor(Haynes ported rebuild) has about 45k miles and has bad oil seals which gieve me alot of blowby. I also have a T04S setup.
