550cc injectors don't fit electrical connector?

[bahlorm]

Hey guys. I bought some 550cc injectors that's supposed to fit a sr20. I finally got these stock ones out by ruining them with a hammer and put the new ones in. They fit in the fuel rail perfect but the connectors doesn't seem to fit right. Is this normal, or is there some way to get these connectors to work? I mean they look the same shape but the plastic seems to just barely be too big.

I looked at the 2 injectors and compared the connectors. The new one is slightly different. The ridges on the side are up just a little higher than stock and the bottom part that snaps it in place are different. Should I shave off the plastic on the injector to make it fit or maybe cut the harness and crimp on a connector that fits the injectors?

You need to wire the matching clip from your injector to the harness.bthey are two wires each. Easy stuff make sure your running correct impedance and don't hammer out anymore injectors lol.

[bahlorm]

Okay. I didn't know if maybe there would be issues with that or not thanks. Lol I got fed up trying to get the stock ones out of the fuel rail and broke one.... so I just said fuck it and hammered the rest out.

[brizanden]

What injectors are you using?

[bahlorm]

I'm not too sure what brand. I got the injectors to work. I shaved off the side ridges on the injectors flipped the injector connectors around and switched the wires in the connectors around and it looks like a champ

scary when you have to make it work...hope it works out :)

[brizanden]

Yeah bro should def just grabbed the correct clips you can order all kinds online for like 20 a set

Sounds like STI injectors.

[bahlorm]

They work. I just installed a z32 maf sensor and an enthalpy tuned ecu. The car idles good, smokes a little black and when I rev, it backfires and spits fuel. My injectors seem to work just fine but I believe either my tune is off or maybe I have a boost leak around the maf. Or its the wiring itself I did on the maf. Although I only left the car running for maybe 30 seconds and never took it for a drive. It may just be because it's cold?

Found out the brand of these injectors also. They are jecs.

[DennisC]

Are they yellow? JECS is the manufacture of these injectors but you may have ones from a WRX STI.

[bahlorm]

Yes they are yellow.
