Not really.
Hypergear do some very nice turbo's, I have bought around 10 off him this year, most with billet compressor wheels. The chra is a new replacement with whatever turbine/compressor combination you want, and he machines the housings to suit. They can be made in bush core, BB, or ceramic BB. Quite often they are more responsive and have more power capabilities than the BB Garrett equivalent, and they bolt on as per factory due to the factory housings being used where required.
He has many hundreds of satisfied customers.
