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

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. :rofl:

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?

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
