S5 to S4
I currently have a 1990 GTU that is complete and running. The only problem is that it doesnt have a title. The previous owner runs a body shop so I'm assuming someone didnt have the money to fix it so they just left it and then he sold it to me. Here (Kentucky) it's basically impossible to get a new title unless I can somehow get in touch with the previous owner with the title, which is highly unlikely.
I also have a 1987 rx7 with no motor that has a title. So I want to swap the engine, 5lug etc etc, over to the 87. How big of a problem would this be seeing as I have the complete running 90 not just the engine? Are the wiring harnesses completely different or will the S4 harness work with the S5 ecu?
Sorry if this has been covered before but I tried searching and got a proxy error.
Thanks
