Well my tuirbo project is under way and I'm wondering about fueling. I have some 470ccs off 2 different RX7 that are getting flow benched and cleaned and i'm running TurboEdit. First question is at 10psi on a D16A6 can I run the stock pump? Question 2 with the same setup can i run the stock pump with a Bosch inline pump? Or sould i dish out the $ for a Wolbro and drop the tank?
Thanks for the replys

BBk is a lot quiet, than walboro and yes you should get an aftermaket fuel pump

holley/walbro 255lph is the common choice.

Well sorry to be a little OT but
I just swapped my 1991 DX hatch fuel pump for a 1992 Acura integra RS fuel pump.
I really don't know if that will make a difference in fueling but the RS pump was free so I just trow it in since the tank was down for earls and braided line fitting replacement...

if someone know the fact, please tell me if the B18 fuel pump is bigger than the DX 1.5 l. thank's

see ya

i think the only time most people run an inline is with a fmu and a billion psi fuel pressure...ide just go with the 255

91 Civic Si here... Holley upgrade pump 255 LPH for a Eclipse GS-T was a drop in swap on my car. Bolted up like stock and everything.

If you're a little short on cash, you can buy JUST the walbro pump [you really don't need any of that other ****] and reuse your pre-pump screen from your stock pump. It's what I did.

kyle h.

get a walbro 255, they are cheap and come with the screen/filter anyways.

Scott (CrazyCompression) and I actually just finished up Will's fuel system for his Rex yesterday. I'll get some pics of it up later and you can see how we setup the pumps (twin Bosch's as pictured above). The reason we changed out the fuel system was because even with Walbro 255lph intank and the inline MSD 125 we were dropping pressure beyond 450whp. A lot of guys get away with an intank and more hp but I just don't see how it is possible. If you're not going for anything much higher than I mentioned you should be fine with that combination. Otherwise sump the tank and run an aftermarket pump(s) and lines. Just my $0.02 good luck
