i'd shop around for what tuner your going with, then ask them and your "end" goal, for your truck.

I feel like a 38r and some 160/30s (Stage 1) or 175/80s (Stage 2) would be a good combo, should make about 400 or so horsepower with the proper tuning. That is more than likely what I am going to go with when the time comes.

If your buying injectors, go bigger with hybrids and have them tuned to suit. Take a look at my Sig......I absolutely love the way my truck runs!

Remember he has PMRs, I don't know if that would make much of a difference but I thought I read that anything over stage 1 or 2 and you run the risk of doing some damage.

A 38r was developed for stock inj's, it works great with stage 1's..which IMO is most I'd use with PMR's.

With dieselsite WW2 and 250/200's and a 38R made 638hp. But....its prolly not gonna last as long as a T4 mount setup. But for the ops use, 38R is pretty good turbo. Or you can go the D66 route, and there are some housing/wheel options for that too.

D66 isn't a turbo for a SD 7.3 its for a OBS and just like a 38r it won't last long above 450ish HP but it is cheaper to rebuild.
