What fuel pump should I be using for my B16 swap, the 90-93 Integra or the 94 Del Sol VTEC fuel pump? ...or is there a different one? I'm not sure I need a new one but my engine is still running funny and there's not much else I can do with it. It does run rich even at 8200 rpms with my D15 fuel pump.

Let me tell you about swapping fuel pumps...I just did mine...go ahead and buy a H.O. unit like the Walbro, I swapped pumps which included dropping the gas tank and 2 hours later I'm done. It isn't THAT hard but I don't care to do it again but since I went with just a so so pump it won't be large enough when I spray...just decide your goals and buy once. You'll be happier.

 

sir_crx- is the walbro unit a driect replacement or does it require modification to install it?

 

FYI: most stock honda fuel pumps are capable of supporting 200 HP as long as they're in good shape, however, if you doubt it's durability, then go ahead and upgrade.

 

I won't trust ANY 10-15 year old fuel pump made to run a SOHC non vtec now supporting a B16A and then I'm gonna spray it on top of that. If you buy the pump for a 92-95 Civic (if it's not offered for the CRX) you can change the pump out and use all the factory components. Like I said, I have to drop my tank again and put a bigger one in there

 

spraying on a b16a will most definitely get you well over 200hp and therefore would need to get an aftermarket unit...as 1stgen said...up to 200hp the stock unit can handle it and its free
