Confirmation: N55 in 335i/135i Spring 2010
Please merge (http://www.e90post.com/forums/showthread.php?t=339542) Sorry.
According to Bimmerfile, it has been confirmed that the 135i and 335i will be receiving the N55 engine. The 335i and 135i will get the N55 for the 2011 year/this Spring with an 8 speed transmission/start stop option. The 335is will remain with the N54 (assuming along with the Z4 sDrive35is and 740i/li) and have an option for DCT. No word on what the rumored 135is/M1 will use. I know several discussion threads exist on this topic at the rumor level, but this looks to be confirmed. This also tells me that the single turbo engine won't be easily tuned to make more power as the is models still retain the N54. "What this also means is that all of you that were looking to tune your next BMW via the aftermarket for those weekend drag races- your window of time is closing as rumors have this N55 possessing some serious anti-hacking devices in addition to the complex Valvetronic system."

I'm so glad I got my 09 335i sedan. Newer body style, better engine IMO, and tune-ability. I highly think that since the n54 is staying in the more "performance" minded bimmers then that only signifies that the n55 is going to be lackluster compared to the n54

So in short our options for 2011 as far as the 3 series are:
335i - N55 - 6MT or 8AT 335is - Tuned N54 - 7DCT Tough choice since my lease is up in March 2011 and I will be looking at a 2011 3 series |

Excerpt from the link: What this also means is that all of you that were looking to tune your next BMW via the aftermarket for those weekend drag races- your window of time is closing as rumors have this N55 possessing some serious anti-hacking devices in addition to the complex Valvetronic system.

From my readings, no. First, the turbine is twin-scroll which can be a challenge to replicate, and second, the turbine housing also has some other engine parts included (like a diverter valve). BMW seems to not want this engine tuned...

I'm sure bmw put a lot more precautions in place to prevent the ecu from being hacked without detection after what they've seen happen with the N54. Lets not forget about the valvetronic system as well.

Τhis is good for us the N54 owners. Everyone will be looking for a used N54-equipped car and the selling price will be higher...

There are already e90 335i's online under $20k, with 50-60k miles. Used prices will not increase. When BMW's run out of warranty, their prices plummet. |

Plus with people modding in their warranty, it's a smart business decision to protect themselves. Things that blow up may not be related to a mod, but why deal with it when they can limit the capability from the get go.

The fact that the iS models and the upcoming M3 will be twin-turbo tells something...
