    i heard that the JDM B20B came with 10.2 compression and came with 33mm valves. True? or is it just like the USDM?

    I believe that the b20z had a higher CR than the b20b, couldn't exactly remember what the differences were. Give me a second to find out.

    from many observations, many people told me that JDM b20 only came in the B20B version, but with 33mm valves, 84 bore, and a compression of 10.2. Which as the USDM B20B is totally different from the JDM one with smaller valves and 8 compression. So is the JDM B20B is the equivalent to a USDM B20Z? C'MON all you frank motor guys, HELP!
