What O Rings To Use For R32 Gtr Injectors Onto An Rb25det?

[HR31-PASSAGE]

ok i'm putting r32 gtr injectors into my rb25det & i've noticed the bigger/bottom O rings on the engine side (NOT the fuel rail side), the O ring hole is to large for the injector to sit in place! so what O rings should i use the rb20 or gtr O rings?

if you dont understand what i mean let me know & i'll take some pics

cheers luke

i didn't think you could fit r32 gtr injectors on a 25? , most people use s15 480cc injectors if doing a budget build?

really well i was told by the fella i got them off he had them on his 25/30 along with the other parts i got off him.

i went to fit them up & the stock 25 injector O rings where to big for the gtr injector so i thought i just needed new O rings???

might be a DE head (not det) , vaguely the rb25de non vct in r32 used rb20/26 type injectors

If you know someone handy with a lathe you could make some spigots to convert down to 11mm. This is a efi hardware adaptor for a Sr20 down to a 14mm injector.

hmmm thats gay so even if i get some gtr O rings & put on that still wont work?>

I thought that RB26 injectors are low impedance and RB25 are high impedance? Pretty sure that's what I got told at the time from my tuner whilst in the process of upgrading my own injectors, if I remember correctly...

Or does that not matter if the car uses an aftermarket ECU?

thats true & yes doesn't matter as i'm fitting a wolf 3v then a tune

i was going to run gtr injectors on my neo but decided not to.. i had a aftermarket fuel rail to suit which came with alloy collars.. these fit perfect into the injector holes on the intake manifold with the std gtr injector o-ring on the end of it.. i'l see if i have a pic

ok that hole in the red circle can i get an injector that sits inside that inlet?

see pic for what i mean...
