Is b18b JDM? and b18a USM? Are there any major differences other than emissions? I haven't been finding many resources on the b18 a/b. A complete swap with everything replaced and new fluids on the b18a is $2800.

. It is easier to push more horsepower out of an engine than to push more torque so I would rather go with the engine that is mildly lower in horsepower and much higher in torque. In these honda engines 10-15 lbs extra makes alot of difference.
