Whatever turbo you decide on, get a Ball Bearing version. They spool faster than a standard journal, sooo you can run a larger wheel and keep your convertor tight. Nice street-ability and still mongo honkin boost and nice high trap speed with like 2800-ish convertor and maybe 61mm compressor housing with a .63 turbine side. You'll need to free up your exhaust to a 3" to maximize that sized turbo's potential, but your going to do that sooner or later. Good Luck.
