hey, im starting a frankenstein build, and i chose to use the crv block. the only thing is i cant find out the specs on the b20b4 and the b20z2. i even called a Honda dealer and they couldnt tell me. does anyone know what the bore x stroke and compression are on these motors, and which would be the best block to use? and is one better for a turbo setup than the other?

thanks
