If I had to do this all over again from scratch I would try to find a car with a G50 conversion and swap out to a 930 engine or go directly to a 930. The number of issues you have to deal with are substantial including the internal engine oil pump, turbo oil supply/scavenge, timing, fueling, intake plumbing etc.. The 915 puts significant limitations on torque. Optimally you want the mechanical 930 scavenge pump with the corresponding 930 or sportomatic oil tank plus vent/overflow tank. All of these things will nickle and dime you to death when seeking aftermarket solutions.
OTOH, it has been an incredible journey of self-education.
