I'm brand spanking new to this site. It was JUST recommended to me and I wanted to say hello and start off with my first post dealing with turbos. I've been around for quite a long time on many other forums and I wanted to see what information I could gain/offer to this one. So...on to my question...
Can anyone recommend a good company/shop that does turbo rebuilding and porting? I live in Ithaca, NY and I'm looking for someone or someplace that can do this before I install the turbo I just bought (used

). It doesn't
have to be local (although I don't mind driving a distance). Also, what kind of gains do people usually see when porting? Decent or just so-so? If it matters, the turbo is a Garrett T28 that came stock on an S14 blacktop SR20. Any input would rock. Thanks in advance.
