Unfortunately, I totalled my rex about 3weeks ago

, and have been franticly trying to find a decent chassis to swap in to ever sense to no avail. Subies are just too damned reliable, everyone one I find is destroyed or still going strong. Well, today it hit me that the solution to my problem has been sitting in my back yard for the last eight years.
I have a 79' Bradley GT2 thats been sitting around collecting dust with no motor. The subie 1.8 NA is a common and popular swap, so I figure a tuned up ej20 would be killer in a 1600 lb kit car

I have already tracked down an adaptor plate to mount to the dub trans axel, does anyone have a wiring diagram or advice on engine management? I still have the rex, so I can scavange parts from it.
Thanks in advance for any help guys
