The Hell you encounter once you have made extensive modifications to your car, and begin to run into complications further down the line. This can be in the form of things like installing heads and cam only to have a valve spring break or installing long tube headers only to have an alternator wire burn a hole in them or melt thru them. Things like this are what Mod Hell is. Issues that wouldn't have happened had you not started to touch shit.

Jack: In the shop.
Joe: Again?
Jack: Yeah, I installed a K&N filter and the oil damaged my MAF sensor so I'm waiting on the new one to come in.
Joe: Mod hell, huh?
Jack: Mod hell.
