what are the main differences between the old prelude motor and the newer crv motrs? do they have a similar bolt pattern or are they completely differnet? i want to know if you can bolt either one into a 5th gen civic. does anyone know? :eek:

old prelude motor is worthless in anything but that car.. the crv will bolt in, need a mount kit.

No, nothing is interchangeable.

i wouldn't say nothing. you can swap the crank :)

but other than that, yeah the b20a/b21a prelude motors REALLY aren't a b-series even though they are
