Now we know for sure the M2 is not using the standard N55 turbo.

So the M2 turbo is also different than the X4 M40i turbo?

It just might be that whole unit had to be redesigned for X model.

But it was expected that turbo was completely different compared to M235i.

They just created such a public confusion by giving N55 name to an M car.

Yes because the M2 has overboost feature of 370lb torque, so in essence the X4 M40i engine is a detuned M2 (355hp/343).

Yes, which reinforces that M2 actually has a custom turbo as opposed to another iteration of N55 turbo.

The N54 in the 1M was literally an N54, same as the prior year 1/3 335.. No hardware changes.

BMW's marketing department must have serious hand getting this engine named an N55. Different block? Different pistons? Different turbo? Never, in BMW's history, have such changes not resulted in a primary designation change. Not that I think a name matters at all, but you can see how the mouthbreathers react to the N55 label.

Best performance buy from a straight line/tuning perspective? An '08-'10 135 or '07-'10 335. Honestly, when it's all said and done, I bet there are many people who wish the M2 just got a carry-over engine from the 1M.

M2 has a different turbo, based on the HP and power band.

The M2 makes peak HP @ 6500 rpms ; vs. X4 40M @ 5800 RPMs. Same for the M235i; peak HP in the 6000 rpms.

I don't see how the M2 could have this kind of power & power band without a bigger turbo.

Granted camshafts have something to do with the power band, but in order to make HP you need to make boost on the upper RPM range.

Lightbulb M2 Turbo Part# found?

So I did some digging and it looks like the turbo part number on the X4 M40iX is different than the turbo part number on the M235iX... Comparing XI models because that's all i could find for the X4 M40i(which apparently has the same motor as the M2)

I wouldn't call this official but maybe the M2 has a different turbo than a standard N55 motor? Tuners start to get excited?

There is a thread around here somewhere showing a different part number from both the M235i and X4 turbos.

From here https://www.parts.bmwgroup.com/webetk/FzgIdCtrl

M2 turbo/exhaust manifold part number is 11658053153.

M2 cylinder head part number is common to other N55 engines hinting at above being compatible with non M2 N55 engines

In the F87 Technical Training manual that was uploaded here a couple of months ago there is no mention of a new turbo. Yet the manual goes in to minute detail on everything else that has changed from the M235i (and N55 used in the M235i). For example, what has changed in the piston rings, adjustments to the oil supply and addition of a second oil suction pump.

The only mention of turbo changes in the manual concern the overboost function and that a blow off valve without diaphragm from the N20 is used.

Given the information in the manual I'd be very surprised if they omitted to mention a completely new turbo!

The technical training manual didn't mention the supposed closed deck engine block either(though).

So can we not expect to be able to swap n55 turbo with M2 turbo?

Remember that M4 owner going on about how it uses the same turbo as the M235i and that it's potential is way less, and that's the **main** reason that the M4 is worth it? It got like 30 likes. I said it wasn't confirmed but no one listened.
