RX7 injectors for RB26


Recommended Posts

My GTR injectors have a leak in them... even after the seals have been replaced.....and i am considering replacing them with Rx7 injectors... or SARD 700cc.. as they are currently well priced on Nengun.

I have a mines ecu..standard AFM otherwise stock engine.

Can i just replace them? or should i look at fuel pump/fuel regulators/air flow metres etc? Is the NIimo fuel pump good enough etc?

Any thoughts plz?

might be able to get them for ~$100 each - try a mazda wrecker. they shoudl be good for ~340rwkw (100%). from what i have heard they are good units - cheap upgrade. not sure if you can just drop them in - it is likely you will need a tune.

ok cool... just 1 more q.... can i just replace gtr injectors with Rx7 series 4... without having to change and fuel pump etc..... and also if i upgrade to large injectors 600+ do i need to upgrade my other fuel system?

was checking Nengun's website for some injectors and the SARD 700cc are only $600 odd dollars. If i go ahead and buy these... i should upgrade my fuel pump and possibly regulator to Nismo items.... Any suggestions as to what i should do about this? I have a mines ecu... with standard AFM...

Hi,

You will need series 5 550cc red top ones that are top feed(can be used side feed style on RB engines ) and high impedence whereas Series 4 Turbo injectors are low impedence.

i can get you 6 of these for 500$ let me know what you think.

Cheers

    • It's good, but not as good as some people make it out to be on social media. Yes, you can feel the torque come in earlier, yes, it does make the car feel more lively below 4000rpm, and yes, it does feel more responsive, but it's not this 'unicorn' mod.  Everyday driving? Below 100km/h on Australian roads, it's worth it. At 110km in 6th gear mine will sit on about 2860rpm. Doing a Motorkhana or a small circuit? Yes, it's worth it. Doing Texas style speed runs? Prob not. Do you use the gears more? Yes and No. Doing 60/70km on most roads, I'm using the gears just like any other Getrag. 80km and above, you use 5th and 6th more often. Absolutely no issues driving with the 33 A-LSD. Didn't change the front diff, only changed the C&P wheel. Some people say to upgrade to a Quaife etc, but i've had no issue with torque steer or having it wander all over the road. The one thing that no-one really addresses is the issue of the Speedo being out. It's either use a speedo corrector, find a 33 gearbox speed sensor, or use an aftermarket display with GPS speedo.
    • Anyone know or have the timing specs for these cams?   i have messaged JUN for two months with zero response    they are 288in/288ex 11.6 lift
    • That would be a rarity. You can emulate the function of the stalk just by bridging the appropriate pins in the connector. If you can make it function correctly by doing so, then the wiring etc is OK and it is the stalk.
    • I've had these LEDs and a LED EP34 flasher relay in the car since 2020. No fuses were popped either. I'll multimeter and clean off the tarnish tomorrow. From how the lights were acting after I diddle the stick make me lean towards a stalk problem.
    • Are you sure you can use LEDs in the indicator lamps? On a car that old? It doesn't work on many old cars because the indicator relay can't cope with the wrong impedance out at the lamp positions and the LEDs will happily light up even with minimal current flowing through the indicator relay. And when I say "indicator relay" I mean the flasher, not a relay relay. Beyond that, I would say that you have caused yourself a wiring fault and that you would be well advised to work through the wiring diagram and the actual loom with a multimeter.
