N26 vs N20 engine my review.
So i have a 2013 Msport with an n20 but i got for a loaner a new base <premium pckg> 2013 with an n26.
The n26 has NO turb lag.. mine does. The n26 feels faster to me. The base model 3 is horrible. The brakes feel smaller, non nav sucks, dash without enhanced screen is cheap, pirellis tires spin much easier, flat seats, comfort access for trunk by sweeping your foot is very slow. n20: My interior is much nicer with sport seats and blue trim piece. Msport steering wheel looks and fells MUCH nicer. sport auto trans is better For the $6k price difference for my M is a no brainer. I got nav, enhanced BT and better styling, sport transmission and sport seats. So below thats a shot of the blow off on the loaner..N26 right?

Im not sure.. i heard only california and other strict emissions states got the N26 which has a more controlled electronic blow off valve.
The pic is of the new N26 valve setup. Seriously though it has NO turbo lag.

N26 is the SULEV version of N20.
I don't know if there's any performance differences. But my wife's E46 had a SULEV engine and it was better for several reasons. Many of the parts were stainless steel and it came with an extended 150k miles emissions warranty. Basically anything along the fuel system (Check Engine light OBD stuff) will be replaced for free by BMW. We had a stainless steel gas tank replaced at 110k miles. It would've cost $8000 at the dealer. |

Easiest way would be to look at the model code from your vehicle inquiry listing. Code 133O and 133Y are for the SULEV N26. Does anyone know if dyno plots for the N26 are available yet? My CA put down 133Y (South African SULEV 328i) for my build without so much as mentioning it I just hope its got the same underrated performance as the N20.

Just for clarity:
SULEV (N26) = Super Ultra Low Emission Vehicle ULEV (N20)= Ultra Low Emission Vehicle The differences are to do with legislation differences across the world, or states in your likely case. From what I recall, it is mainly to do with the aforementioned fuelling system being comprised of stainless steel. EDIT: Just dug out a reply from BMW UK on this when I asked last year: Quote:

Just to update everyone else, they started putting in the electric boost solenoid on N20's too. My July/12 build is one for example.

Drove a luxury line for 400 miles, NO turbo lag depends on how you drive it. It was still there, quite a bit of it if you are sensitive enough. The car had N26 going by bmwvin.com

FYI, loaners nationwide are N26 I believe. This is only anecdotal, but the VIN decoders I've run on loaners (simple curiosity) have stated to be N26's. I say nationwide because I live in Michigan and believe you me we are the complete, 100% opposite of a strict emissions state. We have zero testing or checks.
As for lag, they all have lag. If you are at a light in an N26 8AT in sport and manual mode (just to eliminate as much "slack" from the response as possible) and go straight to WOT, the car will slowly pick up to ~2K then really take off. There may be some minor difference in calibration that gives the facade of a less present lag effect, but if you hold all variables from a dead stop to WOT at the same light, etc., etc., they're extremely close.

I completely concur with the OP!
My wife's n26 F30 328i with automatic feels so much quicker than my 6-speed n20. To my butt dyno the n26 has less perceptible lag from a stop, and more immediate throttle tip-in. Part of it can be attributed to the 8-speed which doesn't fall off boost during upshifts. But the difference in feel is pretty significant. |

I'm wondering if anyone knows what the difference in the emissions profile is between the N20 & N26?
