I'm a big time do-it-yourself'er and I want to upgrade my S5 turbo. I want to port the exhaust side to try to improve the A/R a little and retain the bearing section but get a bigger inducer and a higher ratio turboine wheel on the hot side. I understand you can only go so big on the inducer to retain a handle on the boost lag but as long as its boosting good by 4000rpms I'll be happy. Is there companys that are selling this stuff online? I'm looking to spend as little as posible and trying to get some experience out of this. It could boost for a month or years for all I care I just want to do it myself. As far as I can tell the only machining that would be nessecary is the bearing housing but thats why i'm asking.

Thanks for any imput.
