I got an 03 1500 5.3. I plan on droping in an sts turbo kit. From what I have read the 60's dont take much abuse and the 80 is the way to go. Whats involved with this swap? I want to know what kinda fab needs to be done to make it fit n work properly. Also whats involved computer wise? Who makes a quality aftermarket 80?

 

do a search on it.
