I've searched the messages, but not found the exact answer I'm seeking on this conversion. How much grief related to wiring and such are we talking about to convert a XT N/a to XT turbo. Assume that I have a donor EA82T car to work with.

The plan would be to put the EA82T engine into the n/a XT, NOT to turbocharge the existing EA82 engine in the n/a XT. Let's assume that the n/a XT is a 4WD 5MT, and the donor car is a XT-turbo AT 4WD.

1. Do I have to swap out all of the n/a's wiring for the Turbo's wiring?
2. Fuel pump and fuel line related issues?
3. Other hidden nightmares?
4. ECU swap?

If it's just a matter of plug and play with minimal grief, I'll probably do it. If not....then I'll just keep waiting for the perfect XT-turbo 5MT 4WD to come along....

Looking back through the messages, some have hinted that the wiring harnesses are the same, but use a different ECU.

Thanks much

all you would realy be changing is the shortblock, or the longblock. everything will bolt on, just like it was forgotten at the factory. you dont need the computer, or any wiring. just drop the motor in there with the turbo stuff on it, and go. if you dont have an knock sensor, thats about the only thing to swap in there as far a wiring goes.

Really! It is just that simple? I know it'll bolt up fine, the wiring issues were what concerned me. The n/a ECU is smart enough to adjust to the additional airflow, etc..? I am suspicious after working on the SVX for so long, where nothing is so simple :banghead:

i know there is also a wire on both na, and turbo cars, that can be grounded, or turned on. on the wiring diagram it looks like a switch, but thats the only other thing i can think of that will be different.

i think you'll also need a turbo crossmember to clear the crossover pipe.

Wow..this is all good news.

Anything else I need to know before I widen my search pattern for my perfect XT Turbo 5MT 4WD to include N/A XT 5MT 4wds?

Maybe I'm paranoid, but I still find it hard to believe that it is this easy...
but if it is.... :headbang: :headbang:

Before everyone else chimes in, I will say it.....NO, dont do it.
Look up EA82T here and then decide, you will probably change your mind.
And do more research before resurrecting a 7yr old thread please.
