Gtr injectors in rb25. What do I need?

[RHDskyline]

I searched and found info. But nothing that came to a conclusion

I have a greddy style side mount intake on my rb25 with stock injectors and fuel rail

I have a got a top feed rail from a NA rb25

So my question is. What do I need to get gtr 444cc injectors to work for my rb25det

Please help as I'm looking to purchase some very soon

I have changed mine over to a gtr I believe... From what I remember anyways. Talk to Joe at powerhouse racing and he can get you everything you need for a great price, fast shipping and very clean look.

I know I can what I need from of places.

But im ballin on a budget here and I found gtr injectors for 115 shipped and I already have a top feed fuel rail so im just asking what I need to do to get the gtr injectors to work in my 25

Rb25 uses side feed high impedance. Rb26 is top feed low impedance. You'll need a top feed rail of correct size, FPR to suit, new injector orings, injector plugs installed on harness and the proper resistor box arrangment if you want to do it properly.

I'd rather spend the $$ on s15 spec-r injectors that are 480cc and work in stock rail with stock plugs.

[RHDskyline]

So I would have to modify the plugs as well then ? Like the injector harness clip?

[Zacho]

you need the ones from an rb26 injector harness. rb25 is different. then solder to rb25 harness, with resistor pack

Now that I think about this I have done this for sure. It was super easy and very straight forward. Like I said contact Joe @ powerhouse racing and he can hook you up.

there are companies like deutworks that make high imp injectors for rb25 they are plug n play instead of having to wire in
resistors or changing anything last time i looked they were a good price

[RHDskyline]

Yeah. Im going to weigh my options now. I really dont want to Mess with my wiring harness

I know there are injectors that are plug and play with my engine. I just figured cause I could get gtr ones cheap I Would see what it would take to get them to work


I'm
Kind of excited. I bought a z32 maf and now im searching for injectors. Those are the only two things for now that I need to get my skyline tuned and see what power it makes

This is the way i went about it when i swapped mine. I had a series 1 motor so i used the rb20 harness. But since your using the rb25 harness just swap the pig tails, really easy. And when converting to top feed use this kit. I can get it to your for 120USD + shipping. Has everything you need. Drops in perfect. Only thing i needed was some fatter O-rings for the injectors.
