What I also thought would be hella cool to do one day. Running a GM TBI setup with mega squirt. This could be dome much cheaper than the stuff I linked above. However megasquirt is far from just plug and play. I want to do this setup one day with the classic TurboToms kit. Ditch the carb and go GM TBI. Complete tunabilty on a sweet classic setup!
Believe us!!!!!!!! When we go off telling someone to search. Its not only for our benifet or because it has been covered a hundred times before. But it while searching you get an understanding of all the options that are around and what each one offers you. So please, go do some seaarching in the megasquirt, turbo and section L-series. Also fuel delivery will be a big one as will chevy V8's as they have the TBI.
Good Luck!
