So basically what are the differences?

How can I make my 328i have the power of the Euro 330i, not US edition.

Obviously the 3 stage intake, but are there any other differences?

Is the ECU different on the Euro model?

I haven't found an answer to this...

Also does any one know where I can buy the 3 stage manifold new or used? Preferably used... I've looked but I haven't found squat.

I thought the Euro cars had direct injection...

Dont think thats an easy swap

Have you looked at FI?

They have direct injection? Wow...

Yeah I'll be doing FI later, but there aren't any solid kits out there yet. ARMA is sketchy.

there is no way. i cant even get my 330 to be the same as the euro version. there are differences about it that are specific to that engine and cant be replicated here in the US. if i can remember its the cats that are different and somthing internally is much different. do more research its here on the forum ive read about it many times but im not going to go looking for it

Direct Injection. The fuel is sprayed inside the cylinders instead of into the airstream before the intake valve. This allows for better fuel spread, cooler cylinder temps, more precise fuel/air ratio, etc. All of that allows for higher compression and therefore more power. It's basically a different engine and only the block is the same.

Wow I had no idea about the Euro models having DI. Thanks! Why the hell do you guys think that the US models do not have DI?

[mike-y]

probably cost reasons.. and marketing. The ~270hp 330 has both DI and valvetronic, so that brings the price up. It would probably be a bit too close to the 335 in specs, and cut sales away from the 335. Since the US doesn't get as many models as europe, and they are optioned differently (can't really get a stripper here), a new DI 330 would overlap too much with the 335 in price as well.

Prolly has to do with the fact that USA has a shitty gas.
Premier gas in Europe is 98 octane.

Damn I would love 268 hp stock with no HPFP and no turbos, plus I'm sure that with some mods you could squeeze 300 bhp out of it.

My eyes are watering at the thought. Damn.

I really want a Euro 330i.

According to BMW the reason for not installing N53 (DI) engine to North American models is due to the high sulphur content of the fuel in NA.

Ahh. That is a valid reason.

[mike-y]

though the 335i also has DI, which we do get in the US.

I guess it's all marketing then...

It's just lame that the 328i is stock with only 230, and not 255.

[TommyK]

^ you have to pay to play 330 owner still spent more on their cars and BMW has a thing were they wont step on other models toes. i wont be surprised if the nxt gen NA engine will have the same HP as the 330.

The 328 will likely receive their new engine within a few months:

Not sure. Not enough info to tell, could just be tuned better.

If you want DI in the US you'rw are going to get HPFP issues.

The HPFP is required to run the DI.

Until we get better fuel, and no Methanol added, the BMW DI solution looks to be a problem.

[Martin46]

you are true... here in EU is problem to find gasoline with less than 95 octane, 98 octane you can find at 90% of towns and also there is Shell racing with 100 octane. That's why there is no problem with running DI

The US octane ratings are different to here in Europe

1. 91 Oct US is = to 95 Oct in Europe

It's ethanol, not methanol.

Does anyone know what kind of, if any, performance gains would be realized from fitting the 330i's intake to the 328i engine?
