I would invest in some S3 (instead of the comp cams) and a Magnus IM. This should allow more efficiency in your setup, equaling more power per pound of boost.

I would use GSC R2 cams. Will work better with the lower revving, "large" displacement 2.4.

They are old style dished pistons not flat top, but yes 10:1. the most boost i have run on 90 is 27psi. that made around 480. I have run e85 at about 35psi and made 616
