325i and 330i have identical engine except for the intake manifold and different software for cam timing and valve lift.

BTW: I live in Toronto but I work in Europe where the car is.
It would be much cheaper to bring 328i from Canada but in 2008 I couldn’t get the M Sport package and the potential of N53 engine made me to get the car in Europe.

What shop did you take it to? I am interested in their "tuning" ability. I live in germany. Also how much euro did they charge. you can PM me the details!!

There is something to see – substantial power increase can be achieved by software modification.
DS Motorsport is 25 years in business. Prior to 2008 European E9x had N52 engine and most modifications they did was on that engine. Their race car is E46.

That is totally untrue the N53 has a traditional throttle body to control air flow-go read about it.

And yes the ecu controls the camshaft-obviously as it has double vanos so varies valve opening duration but not variable lift--it is impossible without variable lift to not use a throttle body--i wont argue just go learn about what you are talking about--nothing to debate--its the specs of the engine

I read enough about the engine, talked about it with BMW technicians and I have the car. The main reason for the power difference of N53B30U0 and N53B30O0 is valve lift. By increasing the lift (by software) the output of U0 can be brought to O0.

BudVlad, not trying to start trouble here, but in a post earlier this year you stated yourself that the N53 DOES NOT have Valvetronic.

http://www.e90post.com/forums/showthread.php?t=341093

Still, its awesome to hear about the N53 engine that we don't get here in the U.S., except for the new 528. Also glad to see some real technical discussion on this board after 4 years of "which scoops should I get" posts!

I never said it did have valetronic-your right it does NOT have valve lift. Nor is lift changed on the n53-This joker who is spouting stuff off cannot even site a source.

I have seen plenty of engine specs documents and the internals of the n53-It simply has DI, no more valvetronic so yes valve opening parameters are going to be different since it CANNOt VARY ITS LIFT The valves lift however much teh cam wants them too-There is not variablility to how much it lifts under different cicumstances. And everything else about the engine is largely the same--except it DOES use a thorttlle body to control airflow and it DOES use a HPFP like the turbo engines since its direct inject and needs a higher pressure pump.

People spout the most wrong info and act like its totoally accurate--I guess if this guy wants to believe that its nothing off me.

So, are the cams for the 330i different from the 325i for n53 cars? Did you change out your cams Vlad?

5erman's english is usually fine. That response was in broken English. I think BudVlad did respond but with 5erman's account.

Edit: before I start some shitstorm, I don't think anyone is hacking anyone's account. They might be real life friends or maybe E90post is on the fritz.

Looks to me like poor spelling and capitalization, not broken English

Can we all just agree that the N53 HAS DI and DOES NOT have Valvetronic?

Totally off topic, during the past 3 1/2 years I've only found a few posts worth participating in, this being one of them. I haven't posted enough to really care about all these cool emoticon thingies. Like this one, for instance



Smiley faces getting wasted? Who comes up with this stuff? Brilliant!

I'm pretty sure that the N53 has no valvetronic. It does have double vanos. Lift is only changed with a new cam. Of course I'm basically citing from wikipedia which isn't exactly the most reliable source. But I have read in a some magazine (don't remember which one) that the N53 has no valvetronic. Maybe it will be like the N54/N55. They'll try it with no valvetronic and then add it later so they can claim better fuel mileage on the new engine.

The cams are the same as 330i. Mechanically the engines are identical. The difference is software controlling vanos. The output of N53B30U0 (325) is 218 bhp output of N53B30O0 (330) is 272 bhp. The 54 bhp increase is mainly by software since the 3stage manifold doesn’t do much for horsepower. I had the car on dyno with the 3stage without the software update. There was little difference in hp but torque was up. The ECUs are identical and the 330 software loaded with no problem. However, there was a conflict with other components and car ran shitty. I had to reload the original software before the re flash.

First nobody posted under my name-that was my post.

Second I rarely use punctuation and capitalization so that is not uncommon.

But back to the point this vlad guy is so frustrating-Even having the engine he doesntn know his ass from his mouth when spoutingn wrong crap out!

Here are the FACTS--not up for debate

1. NO valvetronics exist in this engine--nothing to debate here
2.there IS double vanos which controls valve opening duration-how long the valves stay open--but does not vary the actual degree they open variably
3.throttle body controls air not the valves directly as in a car with valvetronic
4.These cars use peizo direct inject system

5. The engine has a 2 stage, not a 3 stage manfiold--
6. Yes the software is the only difference-in the 2 output version-they have absolutely no different part numbers for the mechanics

I'm to hanged over to read and re read and my legs are numb from sitting on the shitter with my iphone and scrolling at this post. I have the N52 in north America. Can I get this tune with the manifold swap and claim the same numbers or not?

The manifold has two actuators but it’s called 3 stage manifold because of 3 stages of the flow according to the RPMs.

Any tuner who can modify the software can do it. DS Motorsport modifies the N52 engines but I’m not sure what number are they getting. Each engine is individually tuned on dyno. It took 6 hours to tune my car.

I am waiting for a reply from them for N52 estimates. If promising I will take my car over and see what they can do. I will be doing the 3 stage manifold before taking it, as well as headers.

Why are you so abrasive all the time man? You can share your knowledge without insulting people - things work better that way.
