Need new fuel injectors, should I get 85T or 81T injectors or what?

[KnightoftheRound]

Hey all, I finally have all error codes gone except CAS (Even after a new CAS unit, new harness with shielding), but I run really damned rich. It kind-of started after I installed a set of 280cc Airtex OEM replacements from Dr. Injector. The ad said they were OEM replacement, even though I was curious about the 280cc flow rate. (Aren't stock 260cc?) I had the rail off today, and pressurized it, and noticed a LOT of fuel coming out of 2 of the injectors, and 2 more showed leakage of sorts shortly after.

 

SO I need new injectors apparently, and due to my terrible luck with aftermarket replacements, I am just going to get a set of new ones from my work. But my question is, should I get 85 300ZXT injectors (What my ECU supposedly is), or L28ET injectors? The part numbers are different in the computer, but I was under the impression that it was the same injector?

 

If anyone can recall my original horror story with the Z31 ECCS swap here:

You will remember that I was finally able to get my car idling and running good with the injector resistor pack installed (whereas the guide calls for removing it), but my car would not run worth a damn with them bypassed, would hardly idle unless the CHTS was unplugged. Interestingly though, since I got those Airtex injectors I thought I would bypass the dropping resistors again and see if it would run that way now, but nope, it didn't. What I DID notice in doing this, was that it barely idled or just stalled right out with them bypassed..but if I removed just ONE injector connector, ANY one, it would idle better, but unplug a second and it dies? No idea what the hell is going on with that, but its only with the resistors bypassed.

 

But yeah, back to the original question, what injectors should I get? OR should I just go back to stock ECCS? (getting VERY close to this, the Z31 swap isn't worth the last 4 months of frustration trying to get it running right, but I don't want to admit defeat either)

They are both the same size/style so makes no difference.

Thanks for the reply, curious as to why the part numbers are different.

 

Any thoughts on the rest of my issues?

Sorry I can't hep you with the Z31 stuff - I decided that I will skip that lame step w/my '83ZXT and go straight to MegaSquirt...more programmability and better ignition/not stock (which has stranded me numerous times over the years - even after 20 minute waits w/hood up).

Thanks anyway. I am actually converting back to the stock ECCS since it ran way better that way in my case. I have spent way too much time and money on the Z31 swap for the last 4 months trying to make it run right to no success.

 

Simply isn't worth it in my case, since the car is usually my DD.

81 85 turbo same injectors but diffrant holders.
