need some advice - putting an EA82 into a dunebuggy. Engine is out of an 87XT injected w/4 wire dizzy. Already got the swap to carb taked care of, I need recommendations on what distributor to use and how to wire it/set it up.

 

thanks

never mind - found a thread!!

advice, don't use an ea82!!!!!use an ej22..cheers, rbain

+1 - don't use the EA82. Use an EA81 or an EJ22. EA82's are nothing but problems.

using what I have sittin here...which is an EA82 and its fresh

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.

how do I wire the injection without an ECU?

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.

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.

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....

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.
