What turbo should I go with any good ideas ?

what kind of budget are you lookin at

Turbo ?
 

Well not big enough for twins that's for sure

66mm range possibly? Or would that be too much? I've heard of trucks in the 700 range running that size still

a 66 has potential for 750 or so. I've heard the 68 spools like a 64, and pushes like a 71.

I'm getting mine from Chris at ED. We've been talking a couple weeks now about the best turbo for my application. He'll set you straight.

What do you want to do?

Well I'll have to drive it about 30 miles a day other then that have fun with it

Power range? Straight stick, auto? Do you want horsepower or torque?

Good to auto billet tc and input shat I'm after hp

If you are after power only, no towing, then you could go bigger, like a 475 or 78 as a single if you want it somewhat streetable, or hang one of those under a 62 for a set of compounds for a little better street manners.

It all depends on your overall goal. How much power are you looking to make? What exactly do you use the truck for?
