if it were me. i wouldnt hesitate to call tony at mightydiesel and order a II silver bullet 66. i love my turbo and you would be better off away from the stock one

the reason i still have my stock turbo is the exhaust brake feature. i have sold several silver bullets and not one customer unhappy. :hellox:

I'm getting a 62/80 phat shaft rebuilt at the moment... might just slap it on there.. will it spool it good enough with just a smarty???

it will spool fine but its a little small for the 6.7 but it will work dont forget you will need a manifold
