Forget the turbos with that motor and 2900# Duster.

10.5 comp. and the MP 590 cam will get you your easy 9 sec. street ride.

Unless your goals have changed and you want 8,s with it now.

Like others have asked, how fast have you been. Id start with the 572 first and then decide whether or not you want to Bother with Turbos.


No reason to Twin Turbo a 572 with a 2900# car unless you want to run7,s or something.
