Ok.. I purchased my CRX from a friend who has already done most you can do externally to the d16a6. Here's a list...

Intake, Header, Full 2.25in exhaust, Gude Cam, Lightened Flywheel (stock piece), Centre Force DF clutch, short throw shifter.

Just wondering if there should be a bump in fuel pressure to "realize" all these mods?

Thanks alot!

 

Sure, it could help out a little bit..

 

ya but is it Necessary? (spelling)? If so.. what PSI??

stock is 40psi?
