the heat is a byproduct of a lot of things, displacement is one of them.
However, to a point, going down the highway at 60mph doesn't matter if you
have a 1600 or a 3000cc engine, it still takes the same power to push the
vehicle.

Efficiency matters. Compression MATCHING THE CAM matters (it's not just the
CR that makes the engine octane dependent).

In a boxer, the first thing to change is a slightly hotter cam. Next is GOOD
ported heads (big valve heads with stock ports is a waste of $), porting
will be about $700/pr, + parts. Next you can do the crank, or add a turbo
(waterboxer turbo kit coming soon). Most of the waterboxers reputation is
due to old gaskets and using regular coolant instead of the non-corrosive
stuff.
