engine running odd

[JN210]

Well, I got it running, sounds awesome...but, its running on an 89NA ecu? I would like it to run on the 87 turbo ecu. Now one big important thing is of course the injectors, NA are 180cc and turbo is 260cc. when I have the turbo ecu in, it runs aweful, barely if that. and it will run good for a second or two and then die like its not getting enough fuel.

another thing, my boost gauge only gets up to ~0-1psi at full throttle...could there be a problem? im thinking that the turbo is turned waaaay down and would like help turning it up if anyone can help me with that Id love to talk to ya about it and see if its something you can help me with. its a stock garret T3 from nissan rebuilt if that has any effect if I can be helped or not (im sure its all the same or close to)

Im thinking its the injectors for sure, I cant come up with any other diagnosis.

thanks

ur not going to build boost when your not driving with your car

Your car is running bad, and your trying things at full throttle? Especially if you think it's not getting enough fuel? Your engine won't last long at that rate.

As for "turning the turbo up"....as above the car won't build boost if there isn't a load on the engine, if your not building boost while driving then you probably have vacuum leak.

if you used the 89 style turbo injectors you need to use a 88-89 turbo ECU. Wont work with anything else. 89NA and 88-89 turbo also use a different O2 sensor. Read this page and figure it out

no, just light taps on the gas, not getting past 3K. and ive got an 02 sensor in from an 87T, and im going to be taking the upper plenum apart when ive got some days off and put in new turbo injectors designed for an 87T, though all turbo injectors were 260cc regardless what year. I think i know where the vaccum leak is coming from as well.

so run the injectors 02 and ecu of the 87. done.

Is this even a question. Sounds like you should be able to answer your own question. Or...you didn't want us to forget that you have a turbo car now.

none of that, was wanting to make sure that I wasnt the only one thinking that, wanted to confirm my thoughts with the experience of fellow fargonians.
