NEED A s2000 TURBO

I'm looking for a turbo for my 02 s2k, I just wanna ask what would be the best and fastest turbo for my s2k and where can I get it. Any advice/info would be great, thanks.

Edit: I'm looking for something that'd give me atleast 400hp

this is a super 16g it has an updated compresor housing compared to a t3. just check out some test on it.
