This screams for Alex based on location but not sure if he is backed up and able to get to it or not but that would be my highly suggested first choice
You know 4g, you did turbo ls, already have a start on the N platform so a nice 600+ 3 series would be fun unique and still Able to pull DD use. Cost would be similar to a turbo C5 at the end of the day for power level though
Pretend like I’m going to find the time to wire it .. instead buy other cars I don’t need and other projects I won’t finish
Speaking of which JP why don’t you have any cheap go fast 4g cars for sale anymore these days lol
It’s pretty much worth scrap value , between the labor involved in swapping a trans in that thing and finding one in good shape to be its replacement you can buy a running driving similar vehicle
Shoot so many options with the n54 and n55 engines it’s super easy to modify and also keep reliable . Unless you go insane a piggy back will handle most of your needs that the stock fuel system can handle
