Thread: Injectors

Can anyone tell me where you guys are getting your 444cc or 550cc injectors from? I've checked the classifieds on both forums. I've also checked eBay but not to clear on the brands. My goals are 250-275whp on a t28. Currently on 370s t25...tia

subies

Sti? What year/color. I understand I need the clips too.

Injectors from a USDM 2.5L '04 through '06 Subaru Impreza WRX STI. Yellow. Side-feed. Approx 520cc.
Yes, you'll want clips.

I remember that thread..I should probably edit update one of my posts..

I've been running the STI injectors for about 2 years...had 2 ECU updates from JWT in that time..the first tune was too rich and I was running out of injector duty cycle %. The second tune was too lean, although they fixed the duty cycle by lowering the injector latency...anyways, I now have a 3rd tune from them that is in between the 1st and 2nd so it should now be perfect. Just waiting to get my engine back together and in the car to try it out.



btw, 444cc comes from the GTI-R. 555cc are Nismo injectors...come from Skyline?

Hey Ben, were you the one that posted about this site before?

They make adapter clips that convert the harness clips to what ever brand injector. No need to splice your your harness, just plug and play. If you switch to another type injectors later, just get a different set of adapters.

I haven't really looked to see which style are for our Nissans but if someone called they could probably help out.

Wasn't me I don't think. Cool cool.

do the STI injectors also have the same wiring plug as nissan ? or do u need the plugs as well?

The sti`s have subie plugs....but the plugs are the same for a long time....like 91 up i think and they can come from any model

The 444cc I was referring to was off a s15 fuel rail that I saw on ebay but the seller listed them as 480cc?? I also saw the subies but no clips. What are you thoughts on modified jecs 550cc?
