turbo LT1?

Has anyone here put a turbo into their LT1? And if so what did it cost? Does anyone know a good turbo set up? I have a rebuilt block and the top end is new. Heads, cam, rocker arms, pushrods etc.  I'm looking for what the total cost was and what anyone thinks the best brand would be. I'm on a budget so take please that into concideration when replying. Any help would be great. Thanks.

i am stuck between the STS turbo and doing the AFR LT4 swap. www.ststurbo.com check it out ans see what you think.

Thanks for the info. The website has a lot of useful information.
