I'm working on an engine in uncharted territory, to my knowledge - no one has done it before. I need help

the engine is a 210 hp horizontal opposing turbo fuel injected air cooled engine.

to those of you who notice something - yes it is an airplane engine and it is going into an airplane.

BUT, i am adding "hot rod" parts to it.

intake manifold - making my own from carbon fiber

exhaust system - making my own from mandrel bent 321 SS tubing with twin turbos

fuel injection - tearing out the mechanical and making my own electronic injection

spark - removing the magnetos and installing my own hall effect pickups and electronic ignition

should i go on - I'm gonna need assistance and ifin you all here want to help - please speak up. nothin bolt on here, figure out and make it, and i better make it good - i'll be flying at 25000 feet in it
