Does anyone ever use either of these old prelude motors to swap in a crx the b21a1 or the b20a5
 
All I know is that the B21A1 is a peice of shit and has MANY problems. As far as the B20A5...If your lookin' to go B20 with no VTEC conversion you probly want the B20Z...It produces the most HP and tourque out of th B20's.
 
these motors will not bolt in with b series mount kits and then use a cable operated shift mechanism, not solid rod type linkage- they respond hossibly to mods and are quite possibly the worst b series motor ever made- stay away from them
