My car is in Beginning stages of Production and I'm already looking for Mods & things that I'm going to do with it, I think I've seen every you tube video of the car ever I don't speak French or Dutch yet I've seen those too, the wait is killing me!! lol Question is how much power can we have on the N55 have and still be able to drive it reliably on the daily basis. Obviously driving it like normal but some days being a hoonigan & occasional Track day. Oh and with the 6 speed manual.

365 hp.

BMW already tuned it to an acceptable reliable level. If they could have made more hp at an acceptable reliability level they would have.

Now, that's not to say that your level of reliability is the same so if your acceptable levels are lower then you can certainly start modding and adding hp.

A more reliable way to go faster is to start dropping weight.

Boosting it to 450 to 500 whp to 100,000 - 150,000 miles from it. Would it last to that Mileage. I know Dinan boost to 446 HP Wonder how reliable to would be.

If warranty and 'normal' matters to you: BMW considered it appropriate for this car, as overall-package, to tune the engine to 370hp (metric) for putting the power properly down.

If straight line speed, wild burnouts and a long-standing commercial relationship with your tire vendor matters more to you: as much added power as you like till the engine goes *kaboom* or the car unintentionally ends up somewhere off-road.

The second one .

The classic n55 is a tried and true proven workhorse. It will be reliable above stock hp levels no question as many, many cars are out there with simple dp's and tunes with no issues. it's not the engine that limits power in this car, it's the turbo. do the turbo and complimenting cooling bolt ons like the intercooler etc. and your DD can easily be 440whp and still get your groceries without breaking down.

I respectfully disagree.

A more accurate statement would be the BMW "tuned" the N55 in the M2 to a level that:

i) involved parts that were already available (from N55 and S55 engines) and kept the cost of the car to an "acceptable" level (i.e. limited R&D)

ii) provided that the advertised HP number of 365HP was comfortably between the lower priced 235i (at the time). and the higher priced F80/82/etc.

It has nothing to do with "if they could have made more hp at an acceptable reliability level they would have".

There are plenty of N55's out there making considerably more power than the 365 advertised...and they are not exploding.

Now given the "new" 240i advertises 335hp, I wouldn't be surprised if, for MY18 and up, BMW advertises a slight bump on the M2 HP saying a "reflashed CPU tune" or "MPPK" has been done and bumps it to 380HP advertised. This would put the M2 right in the middle between the M240i and the M4 from an "advertised" HP number.

That said the advertised HP numbers for BMW are notoriously understated.

To the OP, you can reliably increase the HP on the N55 using parts/methods that people have mentioned in this and many other treads on this forum...but at the end of the day, IF you blow it up you won't be covered under warranty...unless maybe you go with Dinan parts/tune...but then your gonna pay anyway, lol

Totally agree. I'll never understand why some want to take a balanced and well engineered package and overpower it. Not to mention the potential warranty and reliability issues. Bone stock for me thanks.

I agree. The wonder of the M2 is the exquisite balance of chassis and motor.

As Shiv used to say, the car will last a lot longer if you have "mechanical empathy".

It's an N55 which is common in many BMW models. If you want a much better answer, ask in a forum with a 100x larger pool of owners with experience modding the N55. Like for example, the F30 forum.

Because I think 400whp - 500whp wouldn't unbalance it much. Now I haven't driven it obviously in getting it stock and will at least break in engine before I do anything. I'd like to see if I could boost it a bit more

Exactly I'm right with you there. I love to tinker with my things.

^^^ Agree with the above. Enjoy the M2 for what it is.

Want more power...wait for the CS. It will be properly engineered into the vehicle package.

Artemis, m34m, and Bluedoor are spot on and very wise! Tempting as it may be, in today's world, aftermarket engine modifications can be very tricky!

Need proof? Even Dinan admits that BMW has aggresively tuned the M2's N55 engine! By software tweaks alone Dinan can only get an extra 15-20hp (and ONLY 7ft-lbs of torque!) without going to a bigger turbo and intercooler!



There are other tuners out there, certainly very skilled, but they do not maintain the BMW warranty! THAT should tell you something... "caveat emptor"

Not everybody will be able to get a CS and even then he would want to mod it anyway since he would not be happy with it stock. Some people just can't help it. The m2's limitation right now is just fuel and the turbo is tiny. I really think you could do mid 400's in the car and not have a single problem with the car as long as its maintained and driven properly with quality fuel.

Yes and also keep in mind that the extra 15-20hp advantage is on a best run scenario.

When the car in on a track with engine temperature rising, the 15-20hp advantage through more aggressive tuning won't be there anymore.

There is probably not a lot left on the table if you want 150+k mile reliability. Otherwise BMW would not have had to make so many changes to create S55. If their analysis showed they could meet their reliability targets @ 450hp by boosting a stock N55 higher then they would have done that.

A very good suggestion actually. Being in an F30 now, I have spent most of my time on the Forum in the F30 area. I remember one of the biggest issues with boosting the F30 N55 over stock was charge pipe failures. The stock one was "flimsy" and was bursting under the added strain/pressure. Unless BMW addressed that when building the M2 "tuned" N55 - i.e. by using an S55 charge pipe (not even sure if that's possible) or some other "beefier" charge pipe...it needs to be upgraded.

Keep in mind that the engine in the M2 is a modified N55 with better crank and pistons. Dinan has warranted it's modification in the M235 with larger turbo, etc and the same big turbo kit on the M2 engine produces the same power but with the advantages of the M2s basically beefed up design. People who build their WRS STIs run into piston and ring issues, so if similar modified M235s were having problems I think we would be seeing that by now, and I haven't heard of any. So I think with the M2 engine tweaked by Dinan with 446 hp you'd be able to drive the car for 100k miles.

Is the DCT transmission in the M2 the same as that in the M3/4? If so then we would not need to worry about that failing.

Premium always. And mid 400s I'll be happy. Btw today I saw my first BMW M2 in person and in LBB like I order it. And holy Fuckkk it was gorgeous. I'm glad I choose that color.
