328i Power from a 320i?

[Sherwin@xcede]

The BMW N20 2.0l 4-cylinder Twinpower turbo motor found in the F30 320i, F10 520i & the X1 & Z4, makes 125kw & 257NM on the wheels. A stock N20 found in the F30 328i, F10 528i & X1 & Z4 makes 160kw & 330NM on the wheels.

Xcede Performance is proud to announce that we can take the stock 320i/520 N20 motor to power levels above the stock 328i/528i using Burger Tuning JB4 Stage 2. In fact we take it to 170kw & 320Nm on the wheels. This translates to 195kw & 370NM at the engine. Up from the factory engine rating of 135kw & 270NM. A gain of 60kw & 100NM at the engine!

Here is a stock 520i dyno:

And here is the modded dyno run:

Contact Xcede to convert your 135kw N20 to a 195kw performance machine …

Mmmm think I must pull 125i in by xcede.

 

[DieselFan]

What about MP?

 

[M3_devil]

You pay to play.

335 was on plan aswell but was modded.

it boils down to what risks are acceptable to each individual.

Well done. Top gains there!!!

That's close to e46 M3 power at the reef... Nice.

Why wont MP be more tune friendly, i would jump at this right now

What are the differences between the 328i motor and the 320i motor? Software only?
I cant help but think the life expectancy of these highly strung 4cyl motors will be drastically reduced with the added power output, even bmw themselves are detuning their 328i models to get reliability out of them, thats what happens when you ask accountants to build a car for you...
Does your package include other parts to increase headroom or is it software only?
These 320i models have no problem running away from my 330i here at the reef, i was quite surprised, can only imagine how much quicker they will be with a few extra ponies.

I believe that the difference is more than only software between the 320i and 328i. I am interested to get a definitive answer here as I have heard differing views on the subject like perhaps different cams and compression between the 2 models. :fencelook:

Well done guys!!!

I'll be sure to watch out for that 520i :rollsmile:

Im at work now. Need to dig up the link. But the guys at bimmerpost have researched this extensively. The cross reference a host of part numbers between the two engines all are the same and the only difference they found was in a piston part # . However, who's to say they aren't exactly the same just bmw covering themselves.

Another point is the n20 in the 1 series which has 160 kw which sits between the 320i at 135kw and 328i at 180kw. Because they never got the hatch in the USA they never researched that. But would be interesting to see if in fact the engines are exactly the same just a software map.

I am really of the opinion BMW is just using different mappings, and making huge profits on the 328i . Its all marketing, and to the layman , I bet he wouldn't even know that the 320i and 328i is in fact the same engine. He just see's the power numbers and a price, and well it's working for them,

Found it on another source - Important to note they both have the same compression!

See what is missing in the above list? The difference in the 320i and the 328i is the pistons. While both have a 10:1 compression ratio the 320i has a different part numbers for the pistons then the 328i. What that exactly means in terms of the ability to boost the turbo pressure and get 328 power from your 320 is not yet known.

Stay tuned as we continue to sift through BMW's technical documents searching for an answer."

Thats really nice power from 320i :bravo:

:thumbs: big numbers

These were old findings.

I have reliable information that states the 320i and 328i from late 2013 into 2014 onwards now share the same pistons as well.

Stock boost on 320i is 0.6bar and on the 328i is 0.8bar

320i boosted to 0.8bar easily achieves a decent gain.

Boosting a 328i is not going to achieve huge gains as its already boosting high from the factory.

I have done extensive research around the 320i's hence my opinion and my findings , owned a 2012 , 2013 and 2014 (F30 320i)

 

[S1NGH 911]

Correct from late 2013 F30 320i and 328i have the same setup.....

 

[symmat001]

So then it's just pure marketing. Once the Motorplans have run out, I think 320i 's are gonna be good second hand buys

Yes indeed. I would rather have MP though.

Adding a JB unit to the car is kinda safe and the support for the product worldwide is brillant.

 

[adamr]

So just do the software change the badge and do the two pipe conversion and you honestly have a 328i with no difference to the one coming from bmw? Aesthetically and mechanically

gearbox the same? could be that BMW saves money there by fitting a weaker gearbox to the lower power n20...
