GeneralDisorder Posted August 13, 2009 Share Posted August 13, 2009 +1 - don't use the EA82. Use an EA81 or an EJ22. EA82's are nothing but problems. GD Link to comment Share on other sites More sharing options...

GeneralDisorder Posted August 14, 2009 Share Posted August 14, 2009 You need an EA82 carb distributor and coil. They are hall-effect units with integrated ignitors. You will lose performance going away from the MPFI - I would reccomend just wiring up the injection - it's a really simple system. GD Link to comment Share on other sites More sharing options...
RMVR53 Posted August 14, 2009 Author Share Posted August 14, 2009 how do I wire the injection without an ECU? Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 15, 2009 Share Posted August 15, 2009 (edited) You get an ecu or you use something like MegaSquirt which is a configureable, open-source fuel and ignition management system. Then later when you want more than 95 HP you can just plug in another engine, change a couple parameters and away you go! The stock ECU's are simple and availible around this board and the XT specific board. I believe an EA82 turbo ECU will work as well as the MPFI was really just a high comp. turbo fuel/ignition system without the turbo.

GD a turbo ECU won't run very well with out a turbo (I ran my turbo ECU to make sure it worked before selling it. idled okay and ran but not very well.)

Gloyale Posted August 16, 2009 Share Posted August 16, 2009 a turbo ECU won't run very well with out a turbo (I ran my turbo ECU to make sure it worked before selling it. idled okay and ran but not very well.) My 89 GL was originally Turbo. I am running without a turbo on the engine (yes I put 9.5:1 pistons in it) but still have the original turbo ECU and it runs great. A turbo ECU certainly would run his project. Link to comment Share on other sites More sharing options...
RMVR53 Posted August 16, 2009 Author Share Posted August 16, 2009 GLoyale, If I am to use an ECU then I will need your wisdom on the re-wire from a 87.5 XT to "other" ECU... I seem to remember you doing something down similar lines of swapping an XT ECU fpr something else and it required wire swaps? Was that for fire/ignition or FI function? The ECU from the donor XT is dead and/or the harness and I could not find another 87.5 ECU to swap in so I decided to use the engine elsewhere....

GeneralDisorder Posted August 16, 2009 Share Posted August 16, 2009 The only difference is two wires on the distributor. Or you can simply pick up any 88+ EA82 FI distributor to go along with your 88+ ECU and you will be fine. GD Link to comment Share on other sites More sharing options...
