There's a difference between being cash limited and cheap. That being said 800hp tyrbo car is cheaper to build than an 800 N/A. The skill set is different as there is some tubeing and mounting fabrication. It's really basic hot roding. I would be my sons (Diszuter) 360 turbo motor in my chassis would run with-in .10-.20 of what my 15-1 572 -1Indy motor runs. It's been together a while with less maintenance than mine.
