These are the gasoline engines that are/were available in the E9x and F30:
N20: 2.0L twin-scroll single turbocharged inline four cylinder, 240 HP (2013 F30 328i)
N52: 3.0L normally aspirated inline six cylinder, 230 HP (E9x 328i)
N54: 3.0L twin-turbocharged inline six cylinder, 300 HP (E9x 335i) or 320 HP (2011-2013 335is)
N55: 3.0L twin-scroll single turbocharged inline six cylinder, 300 HP (2011-2012 E9x 335i, 2013 F30 335i)

This is the diesel engine that was available in the E90:

You can also get 320hp in the N54 with the ZMZ Performance Package upgrade. (You can't get the Overboost though).

I have a 2011 328i and she has the N52: 3.0L normally aspirated inline six cylinder, 230 HP (E9x 328i).

It will have either the N52 or the N51. If the car was originally sold in MA (or other New England state), there is a good chance it has the N51. The N51 engine is the SULEV version of the N52.

:drive:

You're RIGHT. Just checked some cars from cars.com and all have N51 engine :(

Is this a good thing or no? Not sure how this will impact my modification list

I think the jury is still out on whether the N51 or the N52 is the better engine. The BMW claimed horsepower, torque, and performance are the same.

The N51 has some specialized low-emissions components. These could potentially be expensive in the future. But the emissions warranty on the N51 is either 120,000 or 150,000 miles, depending on the component. The N51 emissions warranty also is more comprehensive than the N52 emissions warranty. Overall, there does not seem to be a compelling reason to prefer one engine over the other.

On the E46 (previous generation 3-Series), the SULEV version (M56 engine) had a completely sealed fuel system, with no serviceable parts. Therefore, when the fuel pump failed, the entire fuel tank and system had to be replaced, at a cost of about $8000. :yikes: Obviously, this is something buyers wish to avoid.

On the E90, all components (fuel pump, etc.) are individually replaceable. So theoretically, there is no post-warranty "ticking timebomb".

:drive:

The N51 is sold in any state that follows the CARB emissions rules 100% (which right now is New England states and CA).

Odd, isn't it. E9x N51's have a specially coated, pollution reducing radiator.

Don't ask me why anyone would want that other than eco crazies....a fortune to replace.

Europeans. Weird.

No. Californians: Weird. And you're one, where there are eco credits available to manufacturers for selling SULEVs. Explains a lot.:bigpimp:

You're completely forgetting (typical east coast perspective) the REST of the west coast: OR & WA.

Interesting that Wikipedia only mentions the N51 with the E46. No mention of this engine with the E9x. Someone that has more knowledge of this engine than me needs to edit Wikipedia!

I wouldn't ever complain about being left out of a discussion that revolves around California.

Yawn. It's supposed to be around 70 tomorrow. I think I'll wash my car in shorts, t-shirt and flip-flops and then drive around all afternoon with my top down. :p
