It's not a big deal but if you've driven both cars I don't know how you can say that. The torque on the 335i is a good deal stronger. The n20 is a gem but n55 is simply stronger.

I agree.

They both kick in and surge at LOW rpm. The N55 just has MORE lol.

The summary at the top says it'll be for the N20, but the actual article makes no mention of it. As we know the diesels are getting the PPK first.

I personally don't believe they'll have a PPK for the N20 since the boost is already so high. The N54 had a PPK, and the N55 in the E90 has a PPK, which is safe to say the F30 N55 will have a PPK.

N54 Boost = 7 psi
N55 Boost = 10 psi
N20 Boost = 16 psi

I have had tuned 2-2.3l 4's in my stable for 15 years. 16psi is not high. There is room for an light oem tune netting 20-30hp at the crank. BMW would not make an engine for production so boost stressed stock that did not have room for more.

We'll see, BMW just is always so conservative with their tuning. I'd love to get a Dinan tune, but only after warranty has run out. (PPK would hold me over though)

I don't get why 328i vs 335i is such an issue. Please stop trying to say how the 328i is faster or has a better power/weight ratio than a 335i. It has LESS power and cannot gain as much HP/TQ has an equally tuned 335i EVER. It has better handling than a 335i and better MPG. Those are the selling points!!

Torque doesn't mean it's faster or has better power to weight... Let me re phrase, 328 has better low end torque which makes it a better city car

The whole point of a Dinan tune is it keeps your warranty intact so I do not see the point of waiting.

The 320d with the N47 has over 20 psi, and there´s a PPK offered for it. A new turbo plus some other stuff is included in the kit so its not like they run it stock and just increase pressure and map it, you pay for a lot more than that.

Dinan will replace the warranty, you will loose the original BMW one.

The problem I have with the Dinan warranty is that it's no longer BMW's warranty. It's Dinan's....

Ah, interesting, thanks for enlightening us. Perhaps the same will be for the N20.

[Vitoco]

That´s what I´m hoping for

I still say they're basically the same car with minor offsets that aren't too different. I mean none of us are professional drivers nor should the cars be driven to the limits on city/highway. I watch the torque when I set off from the traffic light and I consistently hit 280+.

Handling! Hehehe. Thats where it is.

Except it doesn't and it isn't.

335i has 300 ft-lbs from 1,200 to 5,000 RPM
328i has 258 ft-lbs from 1,250 to 4,800 RPM

The N20 engine in the 328i has less torque, that comes later in the RPM band, and craps out sooner in the RPM band. Its torque curve is inferior in literally every measurable way. You are objectively full of shit.

No they match the factory warranty, not supplement it.

Unless you obtain the tune and parts and labor AT a BMW dealer.

If you do that, you're golden....

I do not see see the N20 having more ANYTHING than the N55.

BUT

50rpm cannot be felt by 99.9% of the people walking the planet. So there is no reason to describe one as lagging compared to the other in terms of response.

2nd, I am skeptical of anything published by BMW on power figures between the two engines.

Both are underrated, the N20 just a tad more.

I would check back to back dynos of both engines to see peak tq figures, where and how much.

On a load bearing dyno mine did 240ft-lbs(Dynojets have shown more) and 260ft lbs with exhaust.

I think the 335i is definitely marketed towards customers like me:
1. Enjoy the most power possible
2. Like lots of options (Don't come standard on BMWs)
3. Most importantly: The difference in 24 month lease payment in identically equipped cars (minus the lights on the 328i) is less than 100$ per month.
4. My lease payment is tax deductible since I use the car for work.

Of course there are other demographics that they target, but for me less than 100$ per month (before tax) is the clincher

well yea your talking $1200 a year. $2400 over the 2 year lease. Thats $12000 over 10 years! If you start thinking about it like that, it adds up.
