BD Super B 57/65
BD Super B Special, 64/71

I.I. Phat Shaft, 62/65
I.I. Super Phat Shaft, 62 or 66/71

Quite a differance between each one. They hop back and forth to cover all the reg sizes of a well known single turbo.

 

Thanks for the help good info

 

My best single is the GT3788R or a GT3782R. They spool-up fast. They also work decent in twins configuration.

 

What he said, a 62/71 would be better for driving every day(quicker spool) but the 64/71 would be a little more fun if you don't mind smokey lag and give you room to grow.

 

cool advise I think im going to go with a 64/71 sps and get a cam.

 

If you where closer, I would volunter to give ya hand on the cam swap. Those darn tappets are fun to wiggle back into position and those rusty bolts on the bumper. The rest is pretty easy. Which cam you thinking about using? You running a P pump or VP?

 

Thanks, Its a vp I was going to go with a Fletcher cam. I havent done a cam swap in a cummins but I have on other diesels(cat, perkins, mits) I think I can figure it out I got some local resources.

 

I am running a Turbo Re-Source Custom Garrett GT3788R & love it, It spools very fast & I have had no problims with temps getting to hot.
