i can also port and polish turbos. all it includes is making the waste gate port a little bit bigger and taking a polishing wheel and bringing down most of the cast and flashing marks. making it smoother. on an sti it helps with boost creep and tapering at high rpm's. at underground he may do the occasional hand port but for anything else like heads or some other things he sends them to a shop. so if anyone is interested i can at least point you in the right direction or perhaps show you how to do it or what ever.
