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

can you PM me how long you have had the injectors and power you were running with them and the duty cycle at that power. as i have an r32 and im intersted in these injectors

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 .

    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂  
    • Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
    • It's TWO steering wheels actually. 😛 one for each hand They are wheels, and they steer!
