I've had the compressor housing off my P1SC, it's only held on by a few screws. The impeller is pityful,just sad. I want to upgrade it but ATI charges $1200 even if I just upgrade to a P1SC-1,-2, or D1SC. So if I can find a used D1 or P1SC-2, can I just swap the housings and impellers?
My second option is to take it to a local turbo shop and get a better impeller made for mine.
