I am planning my twin turbo build and I am doing alot of modifications to the car as it is now. I was wondering does the radiator have to be set at a angle like it is stock or can I place it vertical? I cut the main cross member uptop and I am going to box it in for strength but I was wondering if I can place it up and down or does it have to be tilted? Also who makes a rad that is like a inch narrower?

 

Check out AFCO radiators, you can get them the same width, they are 3" thick and you can choose a 16" or 19" height and mount it straight up and down.
