Default What's the difference between ej22e federal and California ?

For example, the timing belt appears to be different, but how or why? What else is significantly different about it? Is the mpg the same, or are california cars a little thirstier?

the cali cars have tougher emission standards they have to meet but i dont know what is different on them physically? I would guess cats, maybe timing or fueling. just guesses though.

No difference other than a special sticker and EGR (though many 49 state cars got EGR as well). The timing belt thing is BS. They changed the service interval for CA, but it was the same belt and everything else. Use the 49 state service interval on that part and you will be fine...
