Technical SEI and CINQ 899 same parts?

[vandisian]

is the sei spi engine the same as cinq, looks pretty much the same.
Is the throttle body, coil pack engine mounts interchangable.
Got one in the scrappie which im getting the seats out but got a 100k on my cinq so thought might as well grab stuff while i can.

spi is the same AFAIK

If we're talking 899s then I'm pretty sure the lumps are the same I'm not aware of any difference
