P-porting, while not difficult for a machinist, might not be the best 1st choice for the inexperienced since it's a major mod to the engine (same for trying to set up a turbo). Second, if only 100 HP is expected and the engine will never run over 4000 rpm, a P-port could actually *hurt* output. Oh, and one more thought. a 13B or Renesis really is too heavy for a 100 HP engine, unless you just don't care about managing weight. Most a/c designed for 100 HP are not designed for 300+ lbs of engine installation. Hate to sound like a downer, but....
