i have a B20b with headers and 2.5 inch stainless steel exhaust all the way back, no cats and i have a Ram-Air intake that is in the fender well, not the engine bay, how much hp gains do you think i got with that? or how much hp do you think i make? just trying to get some realistic gueses

 

Hard to say man without putting it on the dyno but even then you will get different numbers depending on the type of dyno its on. Generally you should have at least 10hp more than stock HP rating. And I think that's on the high side.

 

If you're running it with a stock Integra ECU then most likely next to no gains. Have it tuned and I imagine you'd see a small gain though.
