Questions about this cutaway pic...

[andrewrx7]

I downloaded this pic ages ago for my wallpaper at work.....and sitting here drinking my tea, I start to ask myself questions about it.....can anyone enlighten me with answers?!

i) from which engine/model/car does this come from?

ii) is it a std internal, or uprated?

iii) why is there 2 ports on the left half and only 1 on the right?

iiii) the top apex seal is perpendicular to the housing, the other 2 aren\'t - is this normal? I\'ve only seen an apex seal once, ages ago at a visit to Carls\' workshop, and can\'t remember if the contact face is squared off or rounded.

Thanks!

i) RX-8
ii) Standard (but it\'s a cutaway pic of the rotor)
iii) (It\'s a side on pic) Top two are inlet (6 port) and bottom one is exhaust
iiii) All contact the same, rounded
