[oil pan 4]

I don't use a waste gate.

The only other one that might be worth looking at would be a big holset HX40 with the largest exhaust housing you can find.
The T76 comes with a smaller exhaust housing, it will spool up faster and the T76 has a larger compressor than the HX40.

If I was going to run a simple single turbo setup I would go with the T76.
The T76 and HX40 uses what they call a T4 flange. Most exhaust manifolds on these older trucks use a T3 or T4 turbine inlet flange.
Connecting the turbocharger to the manifold is the most technically difficult part of the process, reclocking the housing and bearing cavity, connecting oil lines, turbine exhaust and intake piping is the easy part.

I built my twin turbo setup from the ground up my self, I didn't just go out an buy a kit.
I read compressor maps narrowed the turbo down to a few candidates and went with the HE351VE which is a variable geometry turbo. You don't want one of those, they are a PITA.
