ok. so i took my brothers stock fuel pump that was lying around from the 92 vr4 and installed it in my car. well my knocking problem that kept occuring at 5800 rpm and up dissapeared. i kinda figured the vr-4 pump was better and would help me from running too lean.

anyways. anyone know the lph on our stock 1g awd and the ones on the 3S?

I checked some stuff on dsm.org a week ago when I did my own pump.
Saw the following -
For stock pump -
12 v on stock wiring (I think 16 gauge) - 100 lph
14 v - rewired 10 gauge - 140 lph

I never knew a rewired fuel pump did so much to help, holy crap!
