B20B/Z questions

[sihatchback_RL]

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

Hmmm what did the US spec ones come with?

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!
