hey,
im doing the same sorta swap right now and, i have the same problem,
all the mounts work from the stock engine, except the rear tranny mount is differnet shape, and the b18b tranny mount is too long, so u can get a sir tranny mount for $80 canadian from honda,
the driver side upper mount does not work at all!!!!!!!! gosh
i heard that an sir mount would work here too, but it costs a hell of alot more then what the other guy said, honda said it costs 300...........
hit me back if you find out more about this ok
peace
