How Are People Fitting Gtr Injectors To Their Rb20?

[335]

Hello

I read that people are putting GTR injectors onto their RB20. How? The GTR injectors are top feed. How do you do it?

Help

I read the thread. I think I understand. So I need to buy a resistor pack for the GTR injectors from Nissan, I live in Japan, rewire everything and it works?

The GTR injectors are top feed, the GTS-T are side feed, how are they going to fit?

Help

RB20 injectors are top feed

Thanks

Ok so will fit.

Do I need a tune right away with this? And what gains will I see with it? I have a R33 turbo and exhaust and intake.

Because GTR injectors flow higher you'll need a retune to suit. You wont gain any power from injectors alone, they're a support mod so you can run a bigger turbo and the like.

Thank you

So a E-Manage should be good for this? Or should I go for a fuel computer?

E-MANAGE will work fine

You don't NEED to buy a resistor pack from a GTR, you can just wire in the appropriate resistors into the loom.

You will not need GTR injectors to run a rb25 turbo...its overkill...

Also...when doing the GTR injector swap...you will have to trim the plastic keyway on the plug to fit it...remember that...

Thanks everyone.

So I just buy the one resister and wire everything in like in the link on this page?

I will go with a bigger fuel pump then since I don't need bigger injectors yet.

im getting some gtr injectors but ive been told they will work with no other mods & that i dont need a resistor pack?

i cant see how this is this possible, or am i wrong?

ok i just found this thread which sorta explains that you can run them without the resistor pack but it might fry my power fc!

i cant risk that...help :|

i wouldn't advise driving it un-tuned after installation.

put it this way; driving it from my mechanics driveway onto the tow-truck, and then driving it off the tow-truck and into my garage fouled the plugs!

this pfc was tuned for gtr injectors/z32 which will be the same mods as me. i know it still wont be safe to drive on but should be in the ballpark, i also have a good wideband gauge installed to check afr's.

anyway im more worried about frying my fc if i install these gtr injectors.

cheers

[NWR31]

btw my fc is actually a rb26/gtr fc wired to suit my rb20.

would that make it more compatible with the gtr injectors & much less likely to fry the fc??

ok ive done a lot of searching & it seems even with the rb26 fc i do need a resistor pack to run gtr squirters...

the gtr runs the resistors to, you need them 100%

[NWR31]

yeah thats what ive just read, cant understand why he's saying i dont need em.

i might have to reconsider buying them cause i dont want to root around wiring in resistors & the resistor pack might be hard to find or expensive..

thanks

If you still have a redtop RB20 in the HR31 then you dont need the resistor pack as it runs low imp injectors standard.

[NWR31]

that is interesting to know, but its a r32/silvertop.

thanks for that
