Hey guys I have a 2000 ls integra and I just put a 99' GSR Head on it. It has a street port and 3 angle valve job. I got skunk 2 retainers and valve springs and no cams. Block internals are stock as well. I also have a AEM Fuel rail and FPR. I had my ecu chipped and it runs pretty damn rich. but my question is if i was to buy 270 or 310 injectors what should i run the fuel pressure at w. the fpr.

im a noob, but if its already rich, why would you want bigger injectors? are you going turbo or s/c?

You would need to hook up a wide-band O2 sensor and check your A/F ratio and then determine where your fuel pressure will run best...If you don't want to / can't get to a dyno then your best bet is to puck up your own, the best deal going right now that I've heard of is INNOVATE (http://www.innovatemotorsports.com/lm1.php)...It's kind of pricey, but invaluable in that it can help you keep your motor free of bad A/F mixtures and detonation........
