Hey guys I did search and some say that the 1m uses reinforced turbos and others say its just a regular n54 engine with stock turbos..
Do any of you have any more info? Thanks

[Elie335]

would like to know as well

[N54bimmer]

1m made 331whp and 362wtq from edmunds inside line dyno...thats like an n54 on procede/jb4/cobb map 1...so I would like to know if the engine is the exact same to mine!

[Shellacked135i]

What would this information accomplish?

[N54bimmer]

It would show us that even bmw thinks the n54 can run 13 psi safely?? lol is that even a serious question?

maybe a turbo swap from the 1M when turbos go out?

Doesn't the 335is prove they think it can handle more? And I think the 1M is just the same thing - N54 engine with better tuning. So to answer your original question - no, it's not the same as your stock engine, it is tuned differently.

My first question was is this a serious question, funny how that works
1000's of users of tuned vehicles have shown us the N54 is quite capable of a measily 13 PSI. The only thing the bmw performance package does to counteract the increased boost is a dumb Rad/Fan upgrade and intakes.

Its quite obvious we are ok.

The engine development.

The engine development time was very short – the engineers took about a year to build or less, from October 2009. In December 2009, the decision was made to build the 1M. Dr. Segler has defended the project and is responsible for all major decisions: one year to develop and test the car. Million vehicles undergo thorough testing on the Nürburgring. All necessary tests have been completed in the spring and summer before the bad weather. He said that engineers and designers worked very, very hard to complete the project.

The 1M is powered by the 6-cylinder twin-turbo 3.0-liter N4. For 1M, turbocharger, exhaust system and ECU have been revised so that the engine is rated at 335 horsepower and a torque of 332 lb.-ft., while 369 lb-ft available temporarily with the overboost.The red zone is situated at 7000 rpm.

From this article it looks as if the turbo's are different.

I tried looking at tischer for a part number but you cant specify M models.

[N54bimmer]

Bmw performance pack gives you 20 hp LOL the 1m is running 13 psi its a very different story...

[Shellacked135i]

So again, what will this new found knowledge attain?

Bragging rights? We haz the 1M Motorz

Realoem.com has the turbo and manifold for the N54's listed as:

N54 135i: 11657593015 & 11657593017
N54 1M: 11657593015 & 11657593017

N54 335i: 11657593015 $ 11657593016

So, the part number is the same as for the 135's with the twin setup. They also want $2k per turbo!!!! Ouch.

Good info!

[Beemw335]

Thanks a lot for the info, looks like its the same turbos...its weird that the 335i and 135i have a different turbo??

We have known that for a while. I'm sure it just has to do with fitment as the turbo and the exhaust manifold come as one part.

No same Turbos different manifold. Ask a BMW Tech who has installed these on both cars they will confirm this.

But what is the point really? Still not getting it.

The guy is just looking to see if there are OEM power making solutions that could be sourced cheaply eventually as they start getting upgraded or junked. Not really that hard to get.

[vase330]

Oh ok. I think just getting a DME from the 1M and putting it into a 135 or 335 N54 would do the trick assuming its not tied somehow to the VIN or having the extra hardware it controls. Eventually someone will do it. But still the piggies and flashes are already doing better so its kind of expensive and pointless if its performance you are after. JMHO.

[Jake.M18]

All the turbos are the same int the 1m the 135 and the 335 its all just diffrent in the tuning as we have established. Youd even be surprised that in the X5 5.0 and the X5M they also run the same turbo setup just a diffrent type of tuning in the ECU. You can notice this because if you take your X5 5.0 in for a ECU tune or the X5M in or a ECU tune you will acquire the exact some Dyno numbers off both cars.


Lemme edit before i get flamed maybe the 135 and 335 have diffrent turbos.

[oddjob2021]

actually the x5 turbos are very different than the x5m turbos. the m turbos (s63 motor) are twin scroll and not to mention, they spin opposite! the n63's turbos (x5) spin normally, normal for the turbo world, as do the td03-10t's on the n54.

and there is a slight difference in the n54 turbos, between the 3 and 1, not in power, but in geometry, space constraints.

[vase330]

As for the 135/335 difference, it depends on what your definition of different is. The snails are exactly same ones, but the manifold is a bit different bewteen the 135 and 335. The 135 runs one pipe and the 335 two so ofcousre there is a difference, but OP wasn't asking about manifolds he was asking about snails (Turbos).
