I have a 91 CRX HF with a b18a swap right now and i was wanting to put a b20b in it, would i be wasting my time or would i gain power? my best 1/8 mile time right now is 9.50 . . . . . . . i notice that the b20b only has 127hp, and the LS has 140, would i gain anypower after i put my LS intake manifold and run an LS ecu???
does anybody have a b20 CRX swap? THAnks

 

anybody?

 

b20 with pistons of course

 

people go with the b20b for larger displacement. stock to stock you might think the b20b out it. but when you add pistions, rods, cams, etc.. the b20b would prevail

 

take your b20 block nd go an get you b18a head machined about 50 thousandth put them together with the b20 head gasket and away you go.
