i just bought a 94 civic with a d15b7. i have been looking for an engine to swap it out with. from what i have heard that a b18c1 and a b18c5 are easier to dot hen an h or f series engine. if i go with the b18c1 do i need to change the tranny out too. or will it bolt up? also same for the b18c5. do i need to change tranny's?
