RB20 Fuel System

[Waldo]

hey i have a RB20DET with a 3.5inch exhaust turbo back, hks front mount, high flow turbo, 1 bar boost, pod with heat sheild...and standard fuel system...wat i want to know is how much mroe power would i get by getting GTR injectors a bosch fuel pump a sard regulator and a ecu tune.....i want to run the same amount of boost aswell..would i be getting any decent power gains from this?? i would also add adjuctable cam gears into this aswell....it currently should have around 160rwkw's or sumthing im not sure...

chances are you are running lean at the moment. there is no need for a set of gtr injectors till you are running 190 rwkw. but at 160rwkw your standard fuel pump is struggling and should be replaced.

if you are not going to run anymore boost than what you are already running then you will get little or no performance gain from injectors.

but you should get a fuel pump for safety.

I have the same mods (NO FMIC though) and my car makes 165rwkw @ 0.7Bar.

Yet i have a fuel pump and also a chipped ECU.

My suggestion would be to get the fuel pump also as they help more than most think.

I'd say you'd be looking at 180 -190 rwkw with a tune and pump. My chip gave me 11rwkw!!!

how much power can u get from a high flowed turbo on an Rb20 then?? i wanna get to around 240rwkw....what would i have to do to get me there without replacing the turbo again... i thought if you got adjuctable cam gears and a fuel system upgrade you can reach this goal pretty easy

[Waldo]

also what fuel pump should i buy....i just want somthing that is a straight fit i dont want to weld stuff....is there a bosch bolt in

Does anyone know for sure if a GTR (specifically R33) fuel pump will bolt straight in to an R32 GTS-t?

I have a GTR fuel pump in an R32 GTST, it sorta bolts straight in. It is bigger in diameter so you have to modify the rubber bottom mount, plus I fitted a stainless screw clamp around it and the bracket just to be sure.

Cheers for that SK! Sound easier than fitting an aftermarket job.

I assume the 32 & 33 GTR pumps would externally identical. For $100-$150 would it be a worth while upgrade for someone chasing less than 180rwkw?

[Sydneykid]

Yep:cheers:

Hi-flow can mean so many different things. About all you can do is give the car to a tuner you trust and see what sort of power he thinks the setup can make....

If you make that sort of power then be sure to tell all us other Rb20 owners:)

One more question...

When wiring in a GTR pump to a 32 GTS-t, does it plug/wire up the same? Or do you by-pass the idle resistor, relay it, etc.

Ta for the help
