I have installed (2) trucks with 6.5 turbo set-ups now and they worked great. I used them off of 94 trucks and had no problem except trying to use the oil hole taps on the side of the block.(real Pain in the a##)(6.5 engines use theirs off the front-top of the timing cover) I instead tapped into the oil-cooler lines using Hydraulic fittings and made a 56" x 1/4" line for a Oil Line to feed the turbo. I installed the "turbo-master" arms and I run about 9-11lbs of boost on heavy pulls(could go more but being a 21:1 Engine I don't feel safe)
Both trucks pull alot better but it sure heats the engine up quick when pulling hills. I still need to get a better cooling clutch & Fan for them.
I pull a 36' Camper and it pulls the camper (still a little under powered for my taste) but If I can keep it cool , it should do the job.
