What is the bore and stroke...
#2
been there done that
b20a? thats the engine from the old preludes. do you mean the b20b from the crv? anyways, they all have the same bore of 81mm except the b20b which has a bore of 84mm. the b16a has a stroke of 77mm. the b20b/b18a/b has a stroke of 89mm. and the b18c1/5 has a stroke of 87.20.
someone correct me if im wrong. h:

Sorry. I did mean the B20B from the CRV.
So what then, if I took a B18B, and used rods from a B16A? I would basically destroke the engine, no?

Yes the rods should fit the crank. As long as the bearing size is the same. However your problem will be that the pistons will never reach the top of the cyls. The B16 uses a shorter deck height than the B18. You would have to use custom pistons that make up the diff in deck height to reach the top of the cyls and compress the gasses. That will make a heavier rotating mass and negate the benifits of the shorter stroke.

Ultimately, rods must be matched to the crank in order to be the proper length. In order to destroke or stroke an engine, you need a custom crank paired with custom length rods.
To destroke a b18b, you could use b16B rods and crank, but not b16a. The b16b uses an Integra block.
