The B18C4, from what I've found, is the European relative of the B18C1 motor seen in the US market 94-01 Integra GSR.

For the rest of the (admittedly spotty) details, read the damn thread. h:

There may be some minor differences in cam grind, but AFAIK it uses the same dual-runner intake maniforld and ostensibly the same head.

If someone can find an authoritative spec sheet on the B18C4, that would be fantastic. :run:

Moving on...
