I'm helping build up a friends 96 3500 cummins and now that we got her a new SB DD clutch we're ready to add a turbo and some injectors. She wants to do 120 injectors and add 191 DVs. As of now she has a 0 plate, CAI, 5" exhaust, AFE intake horn, ARP studs, and a DD clutch. I'm thinking a 64/71 turbo would be a nice touch to her set up but she's looking at the phatshaft 66 and eventually uping it up to twins so she can continue hauling a couple 13k lb. trailers here and there. What do you all think?

 

to bg the think 62 0r 64

 

Definately wouldnt want to tow with a 64 or a 66. probably would want to go with something like a 62/68/13 or something along those lines if she's still going to want to two that much weight without it being laggy and the egt's through the roof.
