I'm running a CRX Si with a B16 on a 75 shot and I was wondering
what fuel pump are you guys running? And where did you get yours
from? I did a search but came up with nothing.

TIA

 

stock dx pump on mine. however, everything is sitting in my bedroom. my ls-vtec is coming out of the machine shop next week. i have a venom fuel rail, aem fpr, and a zex fuel pump kit. i have the zex nitrous oxide system on my car, and i have been very satisified with it. i also ordered 4 venom injectors. needless to say, my car ran at least 4 bottles on the 75 shot with the b16. never any problems what so ever, but i have a strong motor. never leaned out either, I was very suprised. my air fuel guage stayed normal, but then again they arent the most accurate. anyway, upgrade the pump, or I heard a rumor that if you have an si pump, run a larger guage power wire to it. heard it makes a big difference. whatever you do, if you upgrade the pump, make sure you do the other fuel system upgrades that I mentioned, and if nothing more then the pump, get a fpr with a pressure guage.

all last summer i ran a b16 w/ mugen chip ecu on a 75 shot ZEX kit. Stock injectors stock fuel pump (Si) and i never had one problem. Retarded the timing 4 degrees ran 1 stage colder plugs. No tuning at all. HOWEVER i would not do this again and I can't believe to this day that that thing didn't blow up. Damn was it quick though. I get all giddy just thinking about it.
