I have a quick question from those of you that have been around this forum/vehicle for a while now, how hard is it to do what he has done/is doing. There were a lot of posts commenting on how impossible of a feat this was. What is the restriction? And is the ECU the main hurdle? I have read through a lot of it but not all.... Just curious..

Edited to add the fact that he has fabricated a lot to throw at this project, so that is one limitation....
