Many of you will already know about ‪@joeygt6794‬ 's build where he's taking an Irish delivered EP80 2E engined car and doing a full GT Turbo 4E-FTE conversion.
I'm helping him out with the wiring side of thing as the engine wiring is not a straight swap if unless you swap all of the body wiring too.
