I have 97 2500 5spd dual 5in stacks, no silencer ring, tst #100 plate, 3k gsk, boost and egt gauges south bend clutch. today my brother was driving my truck and the turbo blew up. i need to know what my options are as far as getting a new turbo or rebuilding my old one. id eventually like to get injectors, nothing to crazy. I want to find the smartest option as far as a new or rebuilt turbo goes. any input would be outstanding thanks!
