I recently removed my PDRHX40-16 to install a KwikSpool HX40-12. I tow quite a bit and wanted to try it. I know I give up alittle on the top end, and MAYBE higher EGT's at higher fueling,But this has been an excellent change,FOR ME. I added the Bank's Power Elbow,I'm very happy with the results. I would like to locate a 14cm2 housing for this Turbo,or how do I contact Kurt,maybe I can still buy a new one. Dave
