for some reason for the past 2 or 3 days I am unable to search. It says "error, try again later". Anyway is there a difference in thse blocks, i am doing a crvtec. Thanks.

 

B20B= 8.8:1 compression.
B20Z=9.6:1 compression.

 

i am just concerned with the block, are you saying the crank and/or rods are different, yielding the different compression #'s. Or are you refering to the motor assembly. I have a b18b shortblock so i have rods and a crank that i know will fit in a b20b, but what about a b20z?

 

The cranks for all of the motors (B20B, B18B, B20Z) are 89mm. The pistons are different between the B20B and B20Z, thus the different compression ratios.
