ok the 2 dsm heads there: we are talking about the f22a engines here. to make another engine fir in there will be a pain in the ass. Also the f22 is a very detuned engine: 8.5:1 CR, not too much lift, and the cam duration is under 160 degrees of the crank rotation. with a proper cam the engine will easily be boosted to 160-170hp. a new set of turbo pistons( 8.8:1cr or 9.4:1) will run only 500 with the rings and wrist pins, then ceramic coat them for 150 more and you will get one sweet ass engine that is ready to be boosted to about 15psi. and about 280hp on a fwd car is more than enough to get you killed.
