Stock is 24 # IIRC. You cannot just increase fuel pressure. You will need 30 # injectors.

What is involved in your winter project?

You can increase the FP and get a little more fuel from your stock injectors. I'm running ~375 rwhp on stock 24's. But, my fuel pressure is turned all the way up.

You can always go full blast on fuel pressure.......but it's smarter to have a small bit more injector than to have a lot more fuel pressure......from a tunability stand-point, anyway.

Do the 30 pounders .

If you're not on a strict budget, upgrade the injectors. Even though I've been running the stock injectors with my heads/cam combo for over five years. I plan on upgrading the injectors this spring to the 32# Racetronix.

I believe the stock Multecs are 22 lbs. in a 93...if you get up near 100% duty cycle you need to go larger...

IIRC the last year for 22 LB Multechs was 1991 or 1992.
