stumpy Posted October 31, 2005 Share Posted October 31, 2005 I have an 84GL that I want to put a D/R 5speed and a EJ22 into. The EJ22 curently is an automatic AWD. I had problems with an engine swap from manual engine into an automatic. The IAC and injectors being different. ? Will I need to use an IAC from a manual engine to make it run properly? ? Will I need to use injectors form a manual engine as well? ? Since the wiring harness will be altered will the above question be a non issue? Thanks for all your input in advance, Stumpy Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted October 31, 2005 Share Posted October 31, 2005 The ECU you decide to use will determine what you have to do. The automatic ECU can be made to work as a MT.....so I would just do that, and keep all the sensors meant for the AT engine. You can read more about what needs to be done on my swap write up www.surrealmirage.com/subaru/swap Quote Link to comment Share on other sites More sharing options...
Snowman Posted November 1, 2005 Share Posted November 1, 2005 I'm currently running an auto ECM in my 5 speed car with no modifications whatsoever. The only problem I've experienced is that once the engine is warm, when I coast to a stop the idle will fluctuate way down then up to 1000rpm like three times before it stabilizes around 600-700. I assume this is caused by my lack of a vehicle speed sensor causing the ECM to get confused since it doesn't know if the car is moving or not.

stumpy Posted November 1, 2005 Author Share Posted November 1, 2005 Thanks for the replies all. I put www.surrealmirage.com/subaru/swap in my files for future reference as I'm sure I will need more information down the road. The auto ECU would be easiest as I think I fried the manual one fooling aroud with it before I got a clue on an earlier project. I willl research to see if there is some way to avoid the idle fluctuating problem. Although with only one leg the faster idle may be a plus. Will think on that one. I have the unit that oregonloyal is looking for and I didn't want to shoot my self in the foot by offering it to him only to find out I need it. Thanks again for all you techinical advice.
