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 .

    • Ok thanks..that was my second question if i can somehow bypass this even with Nistune(that is all i have right now...aparat from stock ECU. So with some aftemarket it can by "bypassed" or make it work?  I know there is Link or Haltech (mainly used). We have ECUmaster here so i will gather some info about it.
    • Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.
    • Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that
    • I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.
    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
