Hey guys Im looking to put a 62, 64, or 66 turbo on my truck but I want as much power as possible with little lag. I also want the most reliable setup as I daily drive my truck and tend to beat on it. MY mods so far are and H&S tuner, Turbo back exhaust and an intake. I just got the head gasket done and replaced the head studs with 425s and I have upgraded my tranny with better clutches and torque converter. Just would like to know what turbo would fit my needs best and what mods I would need to do with which ever turbo to have it as reliable as possible. Also would like to know if it would be beneficial to run the ats copilot with these turbos.
