I had a KSB1-B (S300 frame, sort of) that I wanted rebuilt to a more compatiable turbo (HTB2) to match to my hp (also had about 100k on the turbo).

HTT has a service to do just that.

Prompt, professional, excellant workmanship, good value ($). I would do it again in a heart beat.

Thanks HTT, VERY Pleased Customer.
