Honestly I can't remember how I stubled across it I think it was after I blew my T3/T4 turbo and was looking for rebuild parts for it and then realized I could make a Mitsubishi turbo bigger and better for a good price why not try it. I've got a couple 14bs and 16gs kicking around I could try with. I also got a FP turbo rebuild kit to redo the turbo before I put more power to it.

Also most of the bad review I saw were for the complete turbo from kinugawa being not as good because of Chinese knock off and the bearings wearing out. We are using the genuine Mitsubishi and good FP stuff for the center housing just using their compressor housing and wheel.
