Gdday fellas,

I was wondering if someone could give me some specific info on gtr injectors on a rb20det...after putting the injectors in along with the resistor pack...will the car still be driveable? The car is a r32 with exhaust, hks2535, fmic, fuel pump and remapped ecu...

I was hoping to be able to put the injectors in myself and then drive it to my tuner for a dyno tune to run the larger injectors...can someone tell me if the car will be driveable? and if so how bad will it be? cheers...

Maybe. It'll be ultra ultra rich, probably foul your plugs instantly. That is if it starts. From memory, rb20 injectors are 270 cc, so you're going to 440 cc.

It's easy to change injectors. Maybe just bring your tools with you and do it in your tuner's carpark?

You'd be able to drive it... just barely. Even if it starts. You'll flood it. It will run really rich too and would foul your plugs in about 20min after the car is warmed up.

Standard RB20DET from memory like Manhore has said, is about 270CC. GTR ones are somewhere about 440CC. Again like Manhore has said. SO thats a huge step up without a tune. Its really simple to change it all, two 10mil bolts hold the fuel rail on, and just have the resistor pack ready and do it in the car park. push it into the Dyno and simple.

You're risking damage by running that rich, I wouldn't recomend it.

      I’d love to find some where that can recover the dashes to look brand new and original. Mine has a very slight bubble, nothing compared to some I’ve seen though

      $170K. I asked one of the guys there as a joke if that price was just for the passenger seat as it was where the price sheet was... he tried really hard to crack a smile 😄 He also mentioned that every single part of the car was inspected and either restored or replaced with a new or as new part, or made from scratch. The interior was incredible, every inch like a new car.

      Time for a modernisation, throw out the AFM, stock O2s, ECU into the e-waste bin. Rip out the cable throttle, IACV, pedal, etc. into the scrap metal bin. DBW, e-throttle, modern ECU, CANbus wideband, and the thing will drive better than when it left the factory.

      I agree, don't go trusting those trims. As I said, first step is to put the logger away, and do the basics in diagnosis.   I spend plenty of time with data loggers. I also spend plenty of time teaching "technicians" why they need to stop using their data loggers, and learn real diagnostics.   The amount of data logs I play with would probably blow most people away. I don't just use it to diagnose. I log raw CAN data too, as a nice chunk of my job is reverse engineering what automotive manufacturers are doing.

      I'm aware, but unless you're actually seeing the voltage the ECU is seeing and you're able to verify the sensors are actually working I find it hard to just trust STFT/LTFT. I will say, logging the ECU comes naturally to me because it's one of the lowest effort methods of diagnosis and I do similar things in my day job all the time. Staring at 20+ charts looking for something that isn't quite right isn't for everyone. NDS1 allows you to log almost everything so that's normally what I do and then sort out the data later.
