What are you basing this statement on? So far, looking at both the dyno numbers, as well as a couple of BMW parts sources, they're saying that despite the different number, it's the same turbo used across the line.

Karma?

How about waiting and seeing what turbo is actually in it when tuners get it?

355hp....Not for long.

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.

I think BMW is contradicting itself again. A current 1M owner is finding out the 1M turbos are not the same as the N54. N54 turbos have the wastegate warranty extension but BMW claims the turbos and part numbers are exclusive to the 1M and are not covered under warranty so that owner just had to dish out money for new turbos.

I'm assuming RealOEM just doesn't show this.

Why does it matter? No matter what the outcome is you will say the N54 is better

N54 UBER ALLES!!!

No no, you're misinterpreting what I said, but that's because I wasn't clear enough.

I'm still saying it's not confirmed, either way. So to say it's the same turbo is an assumption, not that it's definitely a different turbo.

Ouch man. I asked a simple question. No need to get all bent out of shape sounding. I take it that the answer to my question is a no.

[twin fed]

I deal with ordering OEM parts all day long for cars. Numbers get superseded all the time and the part doesn't change but the numbers will. Just because the numbers are different doesn't mean that the parts are. It could be manufactured in a different plant is the most common reason or the manufacturer changed. I'm all for it being a different/better turbo, it just might not be the case in reality.

Where was the info regarding a new closed deck crankcase block posted?

The ETK shows a illustration similar to the N55 while the S55 has a different block. The specific part "block with pistons" isn't available as a separate part in the BMW ETK system, so there is no way of knowing if the block has a different part number or not yet.

My guess is that they have either used the S55 block and gone closed deck, or it's just a regular open deck N55 block. It would make little sense to design a second closed deck block besides the S55 block... But I'm pretty sure BMW would have mentioned a closed deck (or S55) block in their litterature and PR material.

[zinner]

different part numbers really don't mean a whole lot maybe it's got different oil and coolant routing. maybe the turbo is 15 cm forward on that model.

Exactly this,it was mentioned in their literature and PR material and has been posted on here hence why it's been mentioned.

Edit:

" The new BMW M2 is the latest compact sports coupé in a long line of legendary road and racing BMWs, such as the 2002 Turbo, E30 M3 and 1M Coupé. Cast in a similar mould, it brings the concept right up to date with the latest in motor sport derived technology. The result is a powerful performer that delivers genuine driver satisfaction on the road, and extreme capability on the racing.

Powered by a new, specifically developed, 3.0-litre straight-six engine with BMW TwinPower Turbo technology, the latest product from BMW M GmbH produces a formidable 370hp, enabling an electronically-limited top speed of 155mph. When equipped with the optional seven-speed M DCT gearbox, the M2 can sprint from rest to 62mph in just 4.3 seconds.


This superb level of performance is expressed visually via unique enhancements to the base 2 Series Coupé body, majoring on style but also reflecting the aerodynamic, cooling and chassis requirements of the new car. The BMW M engineers have worked tirelessly to reduce weight wherever possible, improve rigidity and hone the M2’s responses via sophisticated chassis technology and electronics to deliver a truly rewarding drive.

Engine: A true BMW M six-cylinder powerplant
The six-cylinder engine of the new BMW M2 is entirely in keeping with the finest BMW M tradition. It offers unbeatable driving fun on a racing circuit, yet remains completely civilised in everyday use. With an appetite for revs not normally associated with a turbocharged engine, it features an exceptionally linear power delivery and strong torque across a broad rev range, all delivered with a distinctive engine sound. Rapid responses and excellent efficiency are amongst the benefits of BMW’s innovative M TwinPower Turbo technology.

The new 3.0-litre engine possesses an output of 370hp at 6,500rpm and will rev to 7,000rpm, while peak torque of 465Nm is on tap between 1,400 and 5,560rpm. An overboost function raises this figure by 35Nm to 500 Nm between 1,450 and 4,750rpm. Despite this potent performance, the combined fuel consumption is 33.2mpg when fitted with a six-speed manual gearbox, and 35.8mpg with the optional M DCT. The CO2 emissions are 199g/km and 185g/km respectively.

With M DCT fitted and Launch Control activated, the new BMW M2 completes the sprint from rest to 62mph in just 4.3 seconds (4.5 sec with the six-speed manual gearbox). The top speed is electronically limited to 155mph.

This new, lightweight, thermodynamically optimised, all-aluminium unit is very rigid due to its closed-deck design. BMW’s advanced M TwinPower Turbo technology on the M2 comprises of a TwinScroll turbocharger, High Precision Injection, variable camshaft timing (Double-VANOS) and VALVETRONIC variable valve control. The M2’s turbocharger has been integrated into the exhaust manifold, reducing the warm-up phase after a cold start and thereby helping to cut internal friction and significantly reduce fuel consumption and CO2 emissions. Components including the pistons were sourced from the BMW M3/M4 engine, as are the crankshaft main bearing shells. In order to ensure oil reaches all engine components at all times under the kind of extreme conditions encountered on a race track, the engine benefits from a modified lubrication system; an additional oil cooler for the transmission oil (on M DCT cars) and a further water cooler for the engine keep temperatures stable.

With its four tailpipes, the M2 is instantly recognisable as a BMW M model and the exhaust’s minimal exhaust back-pressure ensures efficient performance. Added to which, the electrically controlled flap delivers the distinctive BMW M engine soundtrack across the entire rev range without pushing volume levels to their stipulated limits."

[ASAP]

This is a lot of talk on something that we have no confirmation on lol... a different part number means next to nothing... for example... BMW has 5 different version / part numbers of N54 spark plugs that it uses that are virtually indistinguishable...

In addition, if this is truly a different turbo, its quite wild that it made the same exact power as a standard N55 on the dyno... even when tuned... lol

I would only believe a wastegate difference as this has changed before... but a maxed turbo is a maxed turbo... if no sizing difference, then no difference at all virtually.

Did anyone check to see if the mirrors are the same part number?

It has been confirmed as a closed deck.

Nothing would be better, it's just strange that it's not mentioned in the tech docs, just in the PR depts press release...

[VinceCarbone]

You geniuses also realize there are different turbo part numbers between n54 135 and 335 turbos? Every engine bay isnt the same. Get a grip and write something worth reading.

The official press release has different wording and does not mention closed deck at all...

The new BMW M2’s newly developed, three-litre six-cylinder engine
represents a symbiosis of exceptional output and outstanding economy. The
lightweight, thermodynamically optimised, all-aluminium unit is low in weight
yet at the same time very rigid in design.

It wouldn't surprise me if it wasn't closed deck as they got details about the wheels wrong.On one page they stated they were cast in the specs to be contradicted later with the wheels being forged!

Time will tell amongst other things such as the Turbo etc
