chopper and bison are the best of the best ... chopper at limit has been doing this since the way back old school knowledge... if Boost231 recommends reed at work turbos there is another great option thx Boost231
Bison. I was all ready to drop some coin on a bigger turbo from him and after we discussed my setup and goals, he suggested just rebuilding my te44, which was about half the price. I like that kind of integrity. Fast forward a few years and the rebuild he did for me still has zero shaft play, runs great.
