I'm building a circle track car. The class rules are SOHC and stock.... looking.... Its a 90 Civic DX with a D15B2 5spd. I've already chosen to switch to a 5spd SI trans from a 90 CRX SI. What I want to know now is how can make this thing get more power!!! I have access to an D16A6 head/cam and am wondering if that will bolt up and make any more power? Any other suggestions on getting more power out of this motor? Thanks in advanced!
