motor swap for 1990 prelude

i got a b21a1 now i need to know if another motor will bolt up to the stock mounts so i dont have to do any mods to make it work

the 90 prelude b series motor is not the same as the newer b series that were found in civics, integras, or crv's. your pretty much stuck with that version but i thought ive seen kits to swap d-series engines in.
