Just wondering if there is a difference between civic and integra stock pumps. For example a civic DX pump compared to a Integra LS pump. I would appreciate any feed back.

yes there are some diffrents, im not sure on the details so im not going to confuse you. i know i have seen a post not to long ago about it, try doing a search. im sure somebody will be nice enough to post it again in the next few days.

keith

my vx and friends ls and gsr pump all looked the same i wanna know about this too

Anyone else?

Bump

been discussed before. (and I got burned by giving wrong info)

so, here is the main idea-
DOHC VTEC fuel pumps are different from NON-DOHC VTEC fuel pumps.

got it?
many people (including myself) have had no problems running stock CX (1992-1995) fuel pumps in their hybrids with B18C/B18CR/B16A swaps... so is it necessary to upgrade a fuel pump in a dx/cx/vx? nope. is it wise? well.. kinda.... will it help power? maybe.. if your motor is craving more fuel because of bigtime mods, you might see a gain in power with a new fuel pump and more fuel pressure.

Thanks, I was just wondering, i am running a B18b with a Drag III kit, but i am tunning fuel with RC 500 injectors, and hondata and was wondering if i could keep a LS pump for fueling or would a GSR pump work better.
