Based on the paperwork that was posted here these seem to flow approximately the same as the 50# injectors. Just another observation for tuning.

I got mine from a remanufacturing company. I sent them an email asking what they tested them at. I'll report back when I know something.

I am thinking for my B14 project these might be a great option ....I just want to run like 15lbs with a GT2871R , on a nice simple PP ECU .....basicly around 300-350whp is what I am shooting for .

What models can you get the clips from? I've heard it's not easy to find the clips if you buy a set without em which is why I have been hesitant to buy them in the past...

there's a way you can use your current harness to interlace w/the STI injectors. There's a post somewhere. Forgot who wrote about it.

btw, since this thread has been bumped..I've been running the STI injectors @ 4 bar w/a T25 and my current 2871R on a JWT tune for about a year and they work fine. No issues at all. The tune runs kind of rich(11.0 A/F at full throttle), but nothing a tweak in fuel pressure a few psi can't fix(got it up to 11.5-11.7).

::EDIT UPDATE::

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.

I used clips from a subaru forester and legacy. I think all subaru clips will work tho.

I bored out the holes on one set to fit the Nissan wires but one plug wasn't snug so I didn't want it to pop out on me. So I just spliced the complete pigtails into the stock harness. Seems like the safest bet.

Connectors are very simple to find, i think every junkyard has a legacy in it.

I'm looking to go with bigger injectors. If I find some 740's I'll sell my STi's.
