How are "normal" airplane engines tuned to run at a lower rpm? What
changes would have to be made to an automotive engine to shift the

the airplane enemy is weight.

Any engine may fit, the lighter is the better.

An automotive engine, with PSRU is always heavier than an airplane one.
An automotive engine burn the same amount of gas than an airplane one

Is automotive engines cheaper than a 2000h core of airplane engine? (with
the PSRU).
