Subaru 2.2 FI

[kguarnotta]

ok - I do keep a notepad with all the work I do on the Van, and record any parts I install along with part numbers for reference.

Funny - you said turbo only, when I called that Fuel Injector Connection - (VERY helpful on the phone) - he said he thought the FI were from a '90/'91 legacy NA motor (I assumed NA meant Naturally Aspirated, as opposed to Turbo).

They currently charge $35/injector for reconditioning. Takes about a week or so.

I've just got to find time when I can take it off the road that period of time...

it very well could be....

the only way i found those injectors was by looking up a turbo of that vintage both with subaru and world pac.

either way, at least you have a p/n now

for cleaning your injectors:

1 day turn around possible.

For some reason these are all in my back yard, but I am sure you can find a New England injector cleaning service.

If your engine is 1990 -1991 - you should use: 16611AA090 Injectors. Or 16611AA310 for 1992+. However, since it may be you have a miss match of parts on your engine, who knows what you need!

ok - the 16611AA310 is not right for my car - or rather it does not match what I currently have. (Based on google search of that, and comparing to what I have). That is what I purchased originally - and it was different than existing.

16611AA120 - looks a lot more similar to what I have already installed.

16611AA090 - doing a search for this - I see one on Amazon - and it looks different from what I have.

As far as fuel injectors go - can you use whatever will physically fit? I don't really understand the difference between them - aside from looking at them - and seeing which ones looks the same. I assume they have different spray patterns, or the inject different amounts of fuel. IS this the sort of thing that you choose one FI over another due to performance? or is only one going to be compatible with my engine.

I'm not necessarily looking for a high performance or FI that is deisgned for racing or anything - it is a brick on wheels

no, you need the 16611 AA120

the way they seal inside the rail is your issue.

look at the seals between the different injectors. hate to say it, but you have to run the style you have or switch out the fuel rails

Another option is getting a later model EJ22 intake manifold and wiring harness.

Jeff at Autoventures could make this happen. That is the route I took - 91 EJ22 here with a 97 intake (OBD2!). Heck, he can ever clean the injectors too! Highly recommend him and his work.

Obviously, you wouldn't want to do this if you were in California.

I have spare set of injector holders from a 94 2.2 you could install those ebay injectors into and get rid of the others. You'd probably need to swap in some new plugs as well but that wouldn't be a bad thing. I could drop them in the mail tomorrow if you want them.
Probably just take an afternoon to swap out.
Also, have you looked up the part number off the ecu to see what it came from? Might help when dealing with other issues.
I'm glad I was able to do this.

I'll add I have the entire intake manifold if by some chance you have an oddball on there....

Wow - lots of great ideas...
I understand - get that one type of FI - 16611 AA120. I don't have a problem with them - just was not sure what dictates the FI you use - it sounds like the Fuel rail determines which FI you use?

Switching to OBD2 is very tempting...the meager feedback from OBD1 is a pain, I really like the idea of plugging an obd2 reader in, and getting instant feedback on my phone. At least I imagine that is how it would work (it did on my more modern vehicles) To do so would require a lot of changes right I have no idea what would need to be changed - aside from the ECU, wiring harness, fuel rails...I'm guessing a lot more?

If I looked on the ECU - is there a code stamped on it to let me know which one I have, or do I just post some pics of what I have.

Additional update - at one point I was wondering about the coil - but couldn't put my finger on why I thought that might be an issue. When talking to the Fuel Injector Connection guys - they suggested checking that. I noticed the spark plug connection for one of them is a bit corroded (looks green inside). He told me the resistance should be 12 ohms, and when they go bad the resistance goes down to like 3 or 4. Before I could even test it - I figured the corrosion indicates I should probably replace it.

I've got the new one in hand, pouring rain right now. Hopefully the weather will clear tomorrow - and I'll put it in.

I am not in CA - previous owners were, and as far as I know it is CA legal now.

Just updating here...

I finally found a short spit of time where my wife is travelling so I can use her car - so I pulled the fuel injectors from my engine Took about 2 hours! Those things were really stuck in there.

When I go to install the cleaned/refurbished ones - I have read to put a bit of vaseline on them when installing - any other tips?

I also plan on contacting WestyVentures.

Mtnhome -sorry I missed your offer - it sounds like a good one. I am not sure what is involved in changing the injector holders and intake manifold...I may contact westy ventures first. I think I've got a mishmash of stuff on my engine.

Anyway - thanks for the tips...I'll let you know how the replacement goes.

Oh yeah - I also found a set on ebay - that have the same number stamped in the side. JS22-1. I ordered these as well - hopefully something will work
