fuel pumps and pressures

[Cnock]

i heard that if u get a high pressure 255lph warlboro then you nedd to get a new fuel pressure rag but if you get a low pressure 190lph warlboro your good with your stock one. i was wondering if anyone knows anymore about the fuel pump sitaution and can hopefully give me some more advice.

I've also heard that the 190lph is fine. MOST people I talk to with the 255lph pump were able to get away with the stock fuel pressure regulator. I had a Supra pump (290lph) on my stock 2g FPR for a few years and the FPR started acting flaky and eventually just gave up and the car flooded every time I tried to start it... An AFPR really is a good idea no matter what pump you get, but you might be able to get away with NOT having one, at least for awhile depending on your choice of pump.

well how much hp and boost will the 190 limit me to? or is it just wrth it to get the 255 because money isnt a problem they bost cost the same.

with a 255 hp your fuel pressure should go up 4 or 5 psi. if you want to get the most out of your ccar you should turn it down to your repective puel pressures. other wise you will always run rich.
