dude no ones really answered ur b20a5 question, anyway, the engine is SHIT! my friend and me were driving he was at 6300RPM and the crank broke in half!, its a piece of shit, also they do NOT have the same mount positions as a CRV b20, and there is NO mounts made to put them into any other car, b/c no one is stupid enough to use it. U cannot! use a b16a head on it!, they wont fit together. Just get the b20a5 outa ur head, they are a stupid engine and is an embarrasment to the honda name. thats y the block is free, b/c they arent worth shit anymore cause everyone knows how much they suck
