First post for me guys bear with me. I've read pretty much every page on the 4cyl. to 8cyl swap to the point its all miss mashed in my noggin. I've listened to the majority and found a donor for my conversion built on 06/92 auto. gt car. not molested just pillfered for trim and cluster. My project is a 04/92 5spd. 4cyl. with this in hand is there a paticular problems i may run into. i thought i did pretty good getting the same year cars. the 8cyl. is just a total but i have complete car in hand. i would like to keep the project a 5 spd but i understand i will have to swap ecms. i don't want to use the stock t5 either. i do have laying around a rebuilt tremec wc. it is from an 1988 lx i once had. will this make a difference in computer choice? one more thing i read several times but did not quite understand a few of the guys talked about "moving pins" in the harnesses to use their 4cyl harness with the 8cyl harness which is better/easier. if its easier to use the v8 stuff how much of the harness is needed? just the engine harness under the hood to the ecm or do i need to aquire the harness inside the car behind the dash?
