N/A to Turbo Conversion
 

Greetings fellow Supra Owners:
I have 2 Supras. One is an immaculate 86.5 N/A w/ no engine. (My mistake) The other is an 88 Turbo, both are 5-Speeds. What steps do I take to plant a GTE in the N/A body. I have engines and W-54 Tranny's but I am wondering about electrical systems. One engine (GTE) came from a 1990 Supra/5-Speed. Do I have to swap out the under-dash harness to make this come to life. The ECU's are different.
