And no $ for $ it's roughly the same, so you get a pure stage 2, that's fantastic but the M3 puts down 500rwhp without pushing the threshold or envelope at all.

If I do Euro Delivery @ 6-7% under ED invoice forget it the $ factor has tipped heavily towards owning the M3.

The cost difference in the US makes an M3 much more affordable. For those os us in the land of OZ the price difference between an M2 and M3 is more like 60k (or even a little more) making the modded M2 a LOT better deal.

Boy do I ever miss the prices of cars in the US.. the gooberment here rips you a new one every time you buy a "luxury" car

Ekkkkk yeah I did not consider that factor. The damn taxes in some countries are just insane! From that perspective yeah makes sense.

I guess we can all say well the M2 N55 has no hub bearing issues and the M2 takes the reliability nod

Oh that crank hub issues on the S55 is even happening on stock cars.

DPs don't add any power on S55 nor sound, S55 sounds funny even with those 3k+ exhaust lol.

I see much more potential on this M2 since it still doesn't have a M2 tweaked firmware nor flash tune yet.

This M2 will eat plenty of S55 right now, as most are on jb4 and not hitting above 480whp/495wtq until they add more octane

Hasn't the M2 been out like a couple months? How can we give it the reliability nod quite yet? Heh.

(Me too, by the way.)

Oh my...what a powerhouse

[rich8102]

Why would DCT on a 335is slip when some M5's with a DCT don't slip with 700+ hp????

[David@ActiveAutowerke]

Great work guys!

Christ, less than a set of wheels and some carbon fiber bits. This is a steal. Now I'm intrigued by this car.

Edit... This price is impossible. Dps and tune alone would be 2k.. no? Has to be at least 8k.

They share the same crank, main bearings and pistons (with the piston rings modified to be used with cast iron sleeves as opposed to wire arc sleeves from the S55). The connecting rods on the S55 are different.

It is debatable that the N55 in the M2 has a closed-deck block. From the looks of it, it's just a standard N55 open-deck and until this has been confirmed through a tear-down, it is a N55 open-deck block IMHO. The S55 is a closed deck block.

So, no. They don't share the same bottom end.

This is such a stupid statement. I mean really.

The F8x can make 500whp on the stock turbos pretty damn easily.

I bet this thing is insane!

Well done Jesse

How'd I know this would turn in to an epic e-peen contest.

"Brah, I can smoke your stock M3/M4 and I saved X, by switching to Geico!"

"Bro-dawg, I'm flashed with supporting mods and will wreck your life, come at me, and I don't care what it cost."

Meanwhile the internet is

[Adem1534]

Really sweet! Don't know why this is being compared to the M4, both different classes of car whether you like one more than the other. M4 is way more luxury and size, don't think anyone who is in love with the M4 will care.

Its actually not debatable at all considering it says this on BMW USA's site "The M2’s fully aluminum closed-deck block design and grey-cast iron liners allow cylinders to endure higher pressure under the most demanding driving conditions." You can read that here: http://www.bmwusa.com/bmw/M/M2/#PERFORMANCE

In terms of the connecting rods, theyre identical. Look up the part numbers, or better yet look at the links below.

M2 Connecting Rod: http://www.realoem.com/bmw/enUS/show...diagId=11_4455

M4 Connecting Rod: http://www.realoem.com/bmw/enUS/show...diagId=11_5598

So yeah, they do share the same bottom end aside from piston rings. They even share the same cams.

There is a lot of conflicting information. It has been gone over ad nauseum.

BMW is known for typos and incorrect information. The M2's block looks identical to the open-deck N55 from the outside. Why would BMW re-tool the N55 block to be closed-deck when the S55 closed-deck is already designed and proven and doesn't need any retooling to manufacture? Doesn't add up. I'll believe the M2's block is closed-deck when I actually see it.

Also, there is still more to a bottom end than just the big noticeable rotating assembly. To say they share the same bottom end just isn't accurate.

If the S55 and M2's N55 share the same con-rods, why not list that in the literature? Again, lots of misinformation.

Dude really? That motor has been out for 5 years that's attached to the same DCT that the m3 has that's attached to the same underpinnings that the M/4 use.

What the heck are you talking about? The "bigger" turbo? The closed deck? What? I'm not seeing something that's so new that will jump out at is and start massive failures all of a sudden.

The N55 has been proven to be a massive vagina when it comes to tuning and (especially) making power vs the N54 it replaced, but reliability is not a downfall on this platform. Especially if you keep it stock.

Because if everyone new that the two motors shared the same bottom end except the m2 has cast in iron sleeves and a closed block, people would realize the m2 actually has a stronger motor. Look at the n54 scene, all the big turbo builds are going to closed decks. It is likely that they use the same casting as they do with the S55 considering the motors share the same external architecture, alloy, bore, stroke, and just about everything else that interfaces with the block. They likely cast a bare block and either LDS coat it for the s55, or hone and cast/press in the iron sleeves for the m2. Switching from open deck to closed deck isn't nearly as much retooling as you would expect. You would be insane to think that the conrods are different considering they have the exact same part number. As for the closed deck question, its definitely closed deck. If bmw states it numerous times in numerous places, then its a closed deck. There is not a single reputable source that says its an open deck. Not to mention the N55 in the m2 is taking significantly more power than the N55 in the 435/335/etc. People complained that the 1M used the same motor as the 135i, maybe bmw heard them out and actually changed the motor. Regardless, the m2 motor's internals are already anticipated to be stronger based off the information BMW has provided.

And spin crank hubs too, don't forget that!

They make it easy at a cost, so how stupid is that statement? Not very at all.
