STi fuel injector compatibility with SR20???? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

TruPlaya2369 · 07-22-2010, 09:46 PM

Hey, I've searched for internet for days trying to find an answer, but I've had no luck. Please help.
Do the factory 535cc sti fuel injectors fit a S13 SR20DET? If mods are neccessary, such as wiring, please be as specific as possible. I have seen ads like this before, but not sure if they are true. Thanks.
My cars=
05 STi
94 Hardbody SR20

Add on this forum:
i have 4 sti injectors in good condition that flow 540cc and are direct drop in for the sr engines.

They install just like stock injectors.

You have to take the gray cap off of the top so the nissan cap will fit when installing them into the fuel rail.

Also you need the sti side feed connectors.

yea they are the exact fit for SR20 fuel rail.

you will just need to acquire the STI pig tails. Which seems the injectors they usually buy need new ones anyway.

Good to know info...

Yeah this is good to know. STi injectors are plentiful on the net and much cheaper than SR20 injectors. @ 535cc and side or top feed options, STi injectors seem to be a good upgrade to me. Thanks for the help.

manY other Subaru injector harness clips will fit. I run sti injectors and I got my clips off a junkyard legacy iirc.

yea i think 2-3 sets work

STI and legacy for sure. But not 100% on the 3rd, i just faintly remember someone saying there was a 3rd set of clips that worked.

*ANY* Subaru side feed injector clips work. I've used some off of a Legacy and some from an early early Impreza maybe(not sure what it was, but it had sidefeeds and clips that fit).

They drop right in as was explained.

There are also harnesses to convert your stock clips to Subaru sidefeeds on eBay if you don't want to solder now.

*brndck* · 07-24-2010, 10:45 PM

/\/\/\ ya those eBay harness clips are cool, but they're $8 EACH.
So..... $32+shipping?
Or ten minutes with the soldering iron. (IMO if you can't solder you don't belong modifying a car).

Z33dori · 11-11-2012, 09:09 AM

NickIsAZero · 11-15-2012, 05:44 PM

Can't you just cut the clips off the injector and just plug-up your factory Nissan clip?
