Its about $2200 for the CHRA. Ouch!

I think its time to close this post,it's not worth it, way too expencive to buy a cartridge,hopeless to try to find a compressor wheel.
Thank u all for the effort!

^^Have you tried Majestic Turbo? I use them to completely rebuild my T-78.

Quick responce but no luck ,the only thing they had to offer was a 34d or one from a T88 turbo which both wheels required the housing to be ported or something like this!

I'm pretty sure they(Majestic) used Garrett internals on mine if I remember correctly. It actually seems to spool up around 500rpm's faster than standard T78's and still has the top end.

Ill check with Blouch tomorrow and see what the cost of the compressor wheel is and if they recommend. I cant imagine someone using Garrett internals, but it be possible. Ill check with Majestic also.
