I've spent the last couple of days poking around on Google/TT.netand learning all kinds of stuff about turbos but still no luck finding what exactly is upgraded from stock to produce a Sport 500. I understand that JWT uses a new CHRA and machines the housings however I'm trying to figure out what wheels exactly it is that are used. I don't think I'm going to be able to afford new Sport 500's so I'm trying to determine what wheels are required to actually create some of my own.
A local shop has told me that all that's required is an upgrade to the wheel on the "hot side" and machining of the housings however I'm skeptical that this is all that's required.
Any help is appreciated.
