The formula for calculating displacement is: (( bore x bore x stroke x pi ) /
4000 ) x No. of cylinders
Plug numbers in the above and you'll find an I5 motor with a 95.5mm stroke
and 82.5mm bore displaces 2552.53 cc; one with an 83mm bore displaces 2583.56
cc ... only BMW would have the chutzpah to label this as a 2.7L motor.

It will ... eventually. ;^)

Indeed ... they made mine. :^)
