I've been wanting to build a turbo setup for sometime. I've asked several times about it and guys have told me not to use my current setup at all for a turbo engine, because all the parts are too lightweight.

My target was around 1200 hp on E-85 blow thru, which I feel would be easily attainable with my current setup. So that being said how much ballpark would it cost to do this with a different engine SB? RB? any tried and proven builds? I feel like it will cost me a lot more to start over with a different build completely.. Maybe I am wrong?
