Fuel Pressure Reg

[adamskill]

hey guys im wondering if its worth my while fitting a fpr to my rb20, and if so what is a ball park psi to run. my mods include

fmic, turbo back 3 inch, walbro pump, splitfires, 13psi, blah blah the usual suspects. i dont have an aftermarket ecu.

im having trouble on start up, the car splutters and hunts and wants to stall, but as soon as its warm it runs fine, abeit a bit rich(proven by dyno), so it sounds like a fuel problem, hence the fpr thought. other than that could it be that the split fires have a higher heat sink than stock coils?

any imput would be sweet. cheers adam

The first thing I would do is clean the AAC valve. As far as the coilpacks go, did you purchase the DIS-001?

[adamskill]

yeah mate, they are the dis-001, for all rb engines. how do i clean aac valve? im going to change o2 sensor, and clean afm

FPR's are a waste of money 9 times out of 10.

For your mods, you do not need one.

You sure you have the right ones? Not all RB engines take the same coilpacks.

You dont fix problems by fitting aftermarket parts. If you have a factory ECU, it should run like factory, with factory parts.

You clearly have a problem somewhere, you need to fix that before you even think about modding.

i upgraded to the splitfires because my stock ones were on their last legs. the dis-001 were fitted by a reputable workshop, and are suitable for my engine. i know there is a prblem, and was after some help to work out what it was. cheers adam

DIS-005 and DIS-008 are also for RB engines. The series 2 also has inbuilt ignitors in the coilpacks.

The AAC is sitting at the back of the inlet manifold, it's a small gold coloured cylinder.

I believe that there is a tutorial on how to clean one in the DIY section. Saves me spelling it out step by step.

It WILL NOT be a problem with the O2 sensor
