All US-spec E36 M3s have 240 HP. Canada was
given a small number of 1994 model 3.0L E36
M3s with euro-spec engines that made 280 HP
but there are less than 40 of them in total.
HP numbers did not change when the switch to
the 3.2L mill occured, only torque increased
on the US-spec model. The euro-spec model was
boosted to 321 HP from the 3.2L upgrade.
The 2001 E46 has 343 HP in Europe and makes
333 HP in US-spec form from the most recent
information I've seen.
