Finally decided on a turbo

Re: Finally decided on a turbo
Those supposively have made something like 1200-1300 hp on 6.0 cubic inches but hard to buy it, because everyone says heads lift over 1000-1100 ish in stock blocks. Maybe it was a s483 billet? Dont know the details but those are good turbos
Re: Finally decided on a turbo
It's doable, but not what I would call reliably. One guy I know of said he was intentionally pulling power out down track to keep head gaskets in it. (Stock 6.0 block)

Re: Finally decided on a turbo
Yeah no point in taking one that far if you cant seal it. But turbo has tons of airflow for a mid to large sized wheel.

Re: Finally decided on a turbo
Keep the crossover piping around 2-2 1/4 to the merge for the turbo. It will help in spooling that turbo with sich a big a/r. I did 2 1/4 for my gt45 with a 1.15 a/r.
