what would be a good turbo upgrade for my application. i want a fast spooling turbo. i have heard that there is a turbo off equipment i can use a s3xx something and i have heavy equipment at my disposal.

 

Most heavy equipment/semi turbo's are going to have too large of an exhaust housing to just bolt on your truck and spool anything even close to fast. They won't be a T3 flange either, so if you did find one that would work you would need an adapter.

If I were you, I would be calling turbo companies and asking them what they recommend for how you use the truck and what your goals are. Probably the easiest/fastest way.

 

you may have got the injectors first. but i got a turbo

 

i like the super b special. thats what i am going to run here shortly.

 

i think the s-300 has a t3, if you found a piece of heavy equipment with a 350- 500 inch motor it might be worth a try to swap turbos and see what it does
