Rb20det/r32 Injector Plugs

[grippy]

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.

your best bet would be 32 gtr injectors with a resistor pack

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)?

I just filed the tab off, no need to have it as the plugs are clipped in from the top anyway.
