Iv got a 96 7.3l, 6 pos, some tranny work, exhast and inake. A guy i know takes stock 7.3 turbos an makes em 66mm, with all new parts. ( i know hardly anything about turbos) . What other mods do i need to run a 66mm turbo? I know other turbos requre more fuel. But not sure if this is a big enough step up. I plan on upgrading my hpop at the end of august, then if i can ima have him build my turbo.

 

I wouldn't run one with stock injectors. I have heard a stock turbo made into a 66mm is lazy so I would upgrade to bigger injectors before you put one on.
