What about just pulling parts from a k20c1 that’s totaled from a junkyard or something? Then getting a custom tune? That way you save on the turbo and pipes and maybe oil and fuel lines?
Stick with Na these cars aren’t power houses you got need for speed get a vette or bike. Cold air, downpipe, tuner wake the car up some but don’t expect to be pulling paint from the hood lol beside 30+ mpg from a daily ??
