Ok I have a set of 6 RX7 550cc Injectors.

These are a great upgrade fr the RB20DET and they are high Impedance so no resistors or GTR resistor pack needed.

I pulled these out of my R32 today as I decided they were way over kill and GTR injectors seemed a better option for my power levels.

They need new seals however I do have the plugs with them.

Part number of the injectors are 195500-2020.

Asking $400 but I am negotiable on reasonable offers.

Payment via direct deposit preferred.

Pics will be added soon.

:D

I made 300rwhp and the injectors were running about 60% duty cycle @ 11:1 afr from memory.

550cc Injectors are good for about 550 bhp on a 6 cylinder.

have u had them cleaned n flow tested? do these straight fit into the rb20?

I had them cleaned and flowed before I installed them in my Rb20 3 years ago. Though they haven't been cleaned since I removed them. They were working fine when I had them in in just they were a little to big for my application.

They are a straight swap just require you to replace the injector plugs on the loom which I am throwing in for nothing.

Dont forget you can mod the inj. socket and use the orig plugs with out having to fit new ones.

Easier to just cut away a bit of plastic in the 550cc socket -

Dont forget to clean them before fitting as well to save heartache as they can gum up if sitting around not used for a month or so.

This is a super deal - I paid $120 each cleaned and tested a fair while ago.

Have you ever had them flow tested? How long ago?

Yeah about 3 years ago. Just before I put them in my car.

They all flowed equally within 1% of each other. From memory they flowed just over 550cc each.

These work well with a power fc and I no doubt would be a good setup on the RB30 Cubes :D .

      Lets play a game - What is causing my oil consumption?

      Hopefully it ends up being something manageable, like a hone, rather than a full bore—it would be a huge relief if it’s not as bad as it looks. Hang in there; these setbacks are annoying, but it sounds like you’re handling it as smartly as possible.

      Are RBs worth building reliability wise

      By Hendasto · Posted

      At the end of the day, it’s all about understanding the odds and being comfortable with the potential cost, whether it’s horsepower on a build or chips on a roulette table. And I have to say, the Laine example made me laugh—some people really do embrace that carefree, “roll and see” attitude!

      Thanks MBS206, i got that PDF but got abit overhelm with all the connections and tracing of wires. I wasn't expecting to plug the dash harness anywhere. i was just going to use my electronics jumper wires to plug into the right pins like ECU power, ecu ground, ignition trigger etc... I do have a few ratchet straps locking it down tight. Fire extinguisher ready and only a small amount of fuel at a time, enough to submerge the pump.

      https://yariksteel.ru/manual/R33/Skyline_R33_elektroprovodka.pdf   Page 18 should be what you want for the Dash Cluster wiring. Though, you don't need the dash plugged in to get the motor running. What you want is power as how GTSBoy said. You need to power the ECU. Find in the above link the ECU pin outs (Verify them before just connecting them up from things written on the internet). Find anything needing power, give it power, find anything needing ground, give it ground. Then give the starter motor power through a big cable, and bridge the solenoid on the starter straight to power too.  ECU will be on, and when you give the starter power, it'll spin the starter motor, and it should start. I also hope you have a proper stand, and not just the engine sitting on some wood. You will want it bolted down properly.
