Looks like ill just build a tite engine. Do the porting and adjust the pump. Considering i do mainly off riad in the jeep and wheel deep snow i want to go and get back reliably and safe each time.

Any one running a tripple-k k27? I have one from one of my old 745i engines. Its a 3.4l and was pretty torky and responsive unit. With the om617 being 3.0l would it be ok to figure it would be a ideal unit to replace the old turbo?
