B18a or B18b ???
I was wondering what is the difference between these two motors that makes the horsepower difference of 130 to 140.
And is it possible to convert a B18a into a B18b ?
-Thanks David-

(on board diagnostics) which is the type of ecu the car has/had in it
obd is less emmissions restrictive than obd 1 both ecu's can be chipped to raise the rev limiter and better the fuel curves but more applications are availble for obd 1

The B18B head also breaths slightly better ( i think from 93-94 the hp estimates went from like 137 to 142). If you plan on getting it ported then it doesn't matter though. Other than that I think they covered it all.
