There is no need to upgrade a fuel rail in a street honda car (is there??), they're more sufficient than you may think, don't waste your money there. As far as the rest of the upgrades, the guys are right. You can't really extract power out of an Integra with a stock auto tranny. Just make it fun to drive.

Either way, I have all those bolt-ons on my GSR, as do many of us, with the exception of stage 2 cams, and yet, there is still no need to upgrade my fuel system.

I wonder, what are you trying to accomplish by adding all this to your car, I mean, what is your goal? You can add as many bolt-ons as you want, but whats the point if you can't put the added power down to the ground with automatic tranny?
