Rb20det/r32 Injector Plugs

My plugs from my harness that connect to my stnadard injectors will not fit the keyway on any of the "direct fit" upgrade injectors!

Is it mandatory to replace the electrical connectors/plugs on the RB20DET when you upgrade the injectors?

Will the plugs from a RB25/26 fit the upraded injectors?

All the injectors I have seen and also the ones I have will not direct fit onto the standard plugs??

This includes Nismo/Sard and Bosch. The standard keyway/ locator is offset and all the larger injectors are center keyways/ locators and are on both top and bottom, standard only on the top.

Any advice appreciated.??

Take a injector down to repco, they should have new plugs to fit them then solder the new plugs on.

i changed all the plugs on mine when i did the upgrade and i think the new plugs were about $35 for all 6

Dont forget the High / Low Impedance issue as well.

You need resistor packs for the Low Imp units.

I fitted RX7 550cc inj. my RB20 and just cut out the key in the sockets so a straight fit on with std plugs.

After being to just jap today I have found that the GTR is the only harness with the same plugs as the large capacity/ low impedance injectors so if you plan on throwing in GTR injectors you will have the same plug issue. Almost impossible to get a hold of GTR plugs as they do not want to seperate from the harness. (fair enough!)

Repco sounds like the go, thanks for the tips.

Be warned if anyone else is planning to put GTR injectors or aftermarket upgrade injectors in you will have to change the plugs. I found that RB25 plugs are different again to both the RB20 and GTR. CA18 seems to carry the necessary plugs for the conversion. Only going on what I saw at just jap today.

I am aware of the resistor pack needed, to change from 14ohms to 2.5ohms.

If you wanted you could file the offset locater pin off the injector so the plugs will fit, or slice a slot in the top of the plug to accept the pin on injector, but i think thats starting to get a bit rough lol, better off with new plugs.

I ended up getting new plugs from Repco. Part no. BK402 and these are a perfect fit. Cost about $16 for a pack of 2. Just crimped them on, now it's sweet.

Just have to wire in the resistor pack and I 'm good to go.

Bringing this thread back. I've just pulled my stock injectors out of my RB20 and i have a set of pink Nismo 555cc injectors to put in (p/n 16600-RR420) but the plug on the injectors are different. Being a Sunday, no where is open to buy new plugs, so i wanted to know if anybody here actually has just filed the locator pin on the injectors or modifyed the plug to fit?

Isn't that what people normally do when fitting GTR injectors to RB20's (slice the locating tab off)?

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
