What four port engine is the new manifold? What is the engine of choice these
days for a n/a aircraft? Skip

The engine of choice would be a later than 1992 with high compression rotors.
Unfortunately they are kind of rare.
There are lots of six ports out there however.
Anything later than an 89 makes a good AC engine.
Earlier ones also work well as there are a lot's of 12A's in gyro's.
