Hello all,

I need a bit of help with the stock flow rating of injectors and whether they are top / side feed / low or high impedance.

I am trying to suss out what will fit in my RB30 fuel rail (I am doing a turbo conversion, RB30 R31 skyline). I have searched online and on the R31 forum but it seems lots of people are running an assortment of injectors without the info behind how.

Can someone please check this list? And help me fill in the blanks:

RB30E: 185cc side feed low impedance

RB30ET: 259cc side feed low impedance

RB20DET: 270cc top feed high impedance

RB25DET: 370cc side feed high impedance

RB26DETT: 444cc top feed low impedance

Does this all look correct? Is there any way to allow my skyline to accept high impedance injectors?

I will be running a VL turbo ecu, and if I can find no other options I will run VL turbo injectors also, but it seems a lot of the other RB series injectors are cheaper and flow better.

Thanks.

I thought RB30E/T were top feed with hosetails?

I'm not sure at all, would anyone be able to confirm about the RB30 injectors?

Thanks very much for those tables mate! Very helpful, once I confirm what sort of injector the RB30's have stock I will use this for reference.

You will have to run the right injectors for the computer you are using or use an aftermarket computer.

Thanks for the help guys. Glad to hear that RB20 redtop are the same as VLT, i'll keep an eye out for those too.

With a VLT ecu, could I run other injector that flows similarly? Or would any different injector require a new ecu?

Thanks.

The injectors will need to be identical or it will run rich or lean or not at all.

Apologies to bump this up again, I need more expert help!

Just wondering, if anyone has had any experience with Bosch Green Top A46-000001 ? Out of a Nissan EXA / ET Turbo pulsar, supposed to be 272cc (only 3cc more than VLT injectors) and are still low impedance top feed with hose tail, same as VLT and RB20DET redtop. Can anyone confirm any of this?

Many thanks for all the time and help.

correct e15et injectors are the very same as the vlt injectors

    • Crazy how good the aero bar looks compared to the stock one
    • Yes, but you will need to rewire all the things that are different. CAS, coils, etc. Yes, but there is no IAT. What? You can use anything you like. It just has to be hooked up so that it will work.     Or are you wanting to just plug and play without having to do any thinking/work?
    • It's been a little over a decade since I bought the S15. As I did on my socials, I'll share some of my favorite pictures from over the years further below. If you haven't realised, pretty much all the pictures in my posts are ones I've taken.  In terms of updates, I don't have pictures, but I acquired a near-perfect pair of fog lights from a friend of mine, so those got swapped in for the pair I already had. As for the JZX110, I just got it back from being fixed. A few weeks back, I was on the highway when I suddenly drove over something with very little time to react. It was probably the size of a soccer ball, but it went under the car and banged into the underside pretty loudly. I pulled over and realized the fluid leaking was fuel, and of course, it was right near my exhaust. This required replacing the fuel tank. If you happen to be in the same predicament, thankfully this car shares a fuel tank with the JZS171, IS200, and IS300, so it wasn't too painful to replace. Enjoy some pictures as mentioned above, including the carnage from the fuel tank and a bonus picture I came across which shows how ridiculously shiny the Bugels are on the 110. So many more pictures I could share of the S15 but this will do for today, enjoy.
