USDM

b20z = 9.6:1

JDM
b20b = 9.6:1

No youre not positive..or maybe you are but mis-informed

USDM B20B = 9.2:1
USDM B20Z = 9.6:1

If you dont agree...argue with Honda and Helms
I talked to Joe about the information on his site..and after a long discussion he agreed with the Helms as well which states 9.2:1.
