I was wondering how I would add a GM GEN III wiring harness to a V6 that was once carb'd? and possibly turbo charged

For those who need more detail, I am looking at a Before Black Hot air Buick turbocharged 3.8...and I want to be able to tune it, so I would change it to EFI and run a GM PCM. I am undecided about changing the trans to a modern unit. just want to control the engine so I can run e85 and my thinking is I could accomplish things that could not be done with that motor b/c of the advances with EFI.

I am thinking out of the box and still have not committed to buying this car as my 'project'. I need to see if I am going to satisfy my needs for; turbo, project car, tuneable ( I own HPT), 'cool' factor, tinkerness (EFI conversion falls in this area), environmentally cool (E85)

discuss? Ideas? Issues? I am tired of the snow so lets talk funky project

 

A buddy of mines ex stepbrother has a turbo GN and he had some kind of tuning software for it but i do not remember what year it was or the name of the software

Have you looked around any buick/gn forums??? Here is a link to an article that Hotrod did about efi systems.. Hope this helps
