Crossover sells the CHRA for our turbo but it isn't cheap. $705. It looks like links to their site get automatically erased. I guess Sam stopped paying his sponsor dues, but his site is still up and running, just google crossover auto. It is under Mazda/ turbo and related parts.
You can keep an eye out for the part outs and try to get first dibs on one from the forum, but then you never know how long that will last. My recommendation is to just live like a monk for a few weeks or however long it takes to do it right with the new parts.
