I don't know a whole lot about the R18 engine, other than they have a ~0.95 R/S ratio, by standard measurement, but the crank is offset from the bore centerline, helping the combustion stroke's efficiency.
They have an integrated header, plastic intake manifold... that's pretty much what I know about them so far. Until the local dealers get me more information, I'm afraid I can't contribute much more than that.

I am working on my engine and got some values from the fuel pump pressure, lub oil pressure, vacuum gauge reading and the OBD readings for this R18A engine.
