Well, I hope you're right. If the M2 is given a more capable turbo then it would no doubt be my next purchase.

There would be no point to create another closed deck I6. The "Forged steel crank" was also in an n54, it may not have been the same exact crank. This new "N55" shares a lot more parts and design methods with the s55 than with the old N55. They did this with the N63 and S63, they share the same block, crank, pistons, and rods down to the part number. BMW isn't gonna spend the extra $$$ to make another closed deck block that uses the same internals as the m4, its cheaper to just rename the S55 block as an n55. There would be no point to create another closed deck block for a car that has a limited production run when they already have the b58 on the way.

Your interpretation of "major internal components" differs to what it really is. I think you're misinterpreting quite a few things.

1. no it's NOT the same block, google pics of the engine bay, it looks completely different. It's already mentioned the closed case deck is different.

2. Again, only Forges crankshaft, crankshaft bearings, pistons and sparkplugs. You do know what those are right?

Crankshaft can be the same size, just forged or cast. Bearings, pistons and sparkplugs are just a small components. Any current N55 engines can put the "S55 sparkplugs" in. I'd assuming crankshaft bearings and pistons would be the same size, most likely just forged to improve stability and performance of the component.

So once again, no it's a completely different engine.

Ps. Now turbo is a major component, components to run a twin turbo vs a single twin scroll turbo ALONE, would require many different major engine components.

Haven't even got to the different radiators, different cooling system, different FMIC, different intake etc. etc.

The m2 engine is a completely separate engine from the old n55. I dont understand the point of an engine code if two engines under the same engine code dont share any internals including the block, which has usually delegated BMW's engine codes in the past.

I'm sorry but it doesn't take a genius to just LOOK at the engine itself. Once again it's a COMPLETELY DIFFERENT BLOCK!

You probably already know, but the crankshaft is already forged in the M135i/M235i version of the N55. Not sure what else is similar.

Yes, that is correct.

In terms of what else is similar? The M2 engine is 95% the same as the M235i.

From what I've read, the pistons is actually the same as the standard N55 except for the top ring, and S55 spark plugs, which anyone can just switch. Basically, from the look of things, it's just stability and reliability reinforcement for a higher standard N55 tune.

As a few 2ers have switched to the S55 spark plugs after stage 1 tune, which is producing more power than the M2.

At the end of the day, M2 is all about handling.

Edit, looks like I was incorrect...

Haha this is quite comical, you said the engines must be different cause they look different? Find me one picture of the closed deck block in the "N55" in the m2 to compare to the s55 block, since as far as im concerned the only block details are that its a 2 peice, I6, aluminum alloy, closed deck block, with twin wire arc spray, the same bore, same stroke and compression as the n54, s55, and the traditional n55. So why the hell would bmw need to make ANOTHER closed deck block out of the same material, the same dimensions, and using the same internals. No company would do that, its unnecessary spending. They reusing the block and rotating assembly between the m5 and 550, both cars with a much higher budget than an m2.

As for the "Major different engine components" for a single turbo vs twin turbo setup. There are no modifications that need to be done to actual engine components (Head, cams, valvetrain, rods, pistons, crankshaft) just because one has one turbo and the other has another. When it comes to differentiating engines especially in terms of engine code designation, the engines internals are what define it not what cooling system is bolted up, or what turbo/turbos are bolted up, but the actual internals. So go ahead and make yourself a chart with a column for the tradtional n55 (not the one in the m2) and the s55 and write down what engine internal components are shared under the respective column. The m2 doesnt even have cast in iron sleeves like the n55 in the 35i's

You are correct sounds much better than the M4.

First thing I did when I heard that vid was email Akrapovic. The U.K. Agent told me they will have an exhaust available from April/May. So should be the same everywhere.

The best or nothing.

Did they mention to you what kind of exhaust?

Forum fellow Alden_88M contacted the Swedish Akrapovič agent last Summer. Here's his comment of Oct 15, 2015:

«Hello and thank you for your interest in Akrapovic !
As the Swedish agent for Akrapovic automotive systems, we received your request for this system. When the development time of each system is very long, there is a limited capacity how many new versions to be developed every year. From a BMW perspective we work at present with X5M system and then takes priority on the new M2, as in the current situation there are no plans to release something to the M235i in 2015. If this were to change, we will feed back to you with information.»

Does he have any update ?
