Sr20det stock fpr question

[stevecorrado88]

So I have 740cc injectors on stock rail and a 3071r turbo on 21 psi. Will the stock fpr work with high boost or should I get a nismo one or any other ???

[tabasco122]

which fuel pump? higher flow pumps have been known to raise the base fuel pressure when still running the stock fpr

[vosko]

stock fpr and rail was fine on my car

Walbro 255 I've been driving the car for about a year with it this way. Ideal is rich afr at low to mid rpm is alittle wavy untill high rpm it smooths out.

It works just fine at high boost, it is idle that the stock fpr can not flow the higher amount of fuel that the 255 puts out

yeah, i was having idle issues with mine. just slap a nismo fpr and a cheap summit fuel pressure gauge. i think i paid $20 for the fitting and gauge. about $150 for the fpr.
