3.0L or M3 engine?

PML will most likely not do the swap for you. You can do the manual-auto shop at any shop that you trust. However, it would be a bitch to get it to be approved by the LTA

what i'm saying is that since rpm for bmws are usually at 6500-7000 there shouldnt be any case of high hp low torque figures, thus bhp should be numerically about the same as torque in lbft, so layman wise can be interchangable since hp and torque is essentially the same thing with rpm factored in. but you're right, tolerances should be strictly compared in torque. anyways in dynos torque is directly measured and bhp is back-calculated by the computer.

Oh, ok thanks for the clarification. errmm... what was the original question again... hahahah!

RB, what's the torque rating for the 343hp E46 M3? Surely not 340ish ft-lb?

shaun drinking too much engine oil again. M3 revs much higher than 6500rpm loh........

Think if I am not wrong, its 269lb/ft of torque...

yeah so I think if is best to go by actual torque rating and guess it from power.

the closer together tq peak and hp peak are (high up the RPM range) the larger the power figure is going to be over tq.
the closer together tq peak and hp peak are (low down the RPM range) the larger the tq figure is going to be over power..


the m3 kind of fits into the former category.. the peaks are not that close, but close enough such that tq in ftlb isn't close to hp
