anyone ever put a b18 head on a b21 block im thinkin about buying this prelude motor and making some good compression with my old head just wanna know if anyone has done it before?
 
The old B-series engines from the 88-91 Preludes have nearly nothing in common with the Civic/Integra B-series engines. You cannot swap parts between them...
 
yea.. the b-series in the 88-91 ludes are like the red headed step child of the b-series family.. they share no characteristics

well couldnt find the rules but if you are allowed to use any stock parts get you a set of pistons for a 2000 acura integra typeR or a 1999civic SI. The integra typeR pistons will net you about 11.9:1 compresion. If you mill .020 off the head and you are at 12.5:1 get you a intake cam from a B18B which is a non vtec integra form like 1999. if you do the piston change run 100octane or higher and get a set of 390cc injectors from a automatic turbo eclipse or talon. car will run a little rich but you should be ok and still fall into the stock parts rules with a unmodified ecu
