based on the info i've researched on honda-tech; ctr pistons will give a b16a a cr of 11.1, is this correct? why the cr of 11.1 and not the b16b's 10.8cr. where does the .3cr increase come from if both motors have the same stroke and bore. waiting to be educated in for my ignorance. thanks!

 

b16b's have a different deck height, the same as a b18c. 7 more mm.

 

yah b16b motors are destroked b18c motors.

 

and the pin location is different on the pistons....
