THANKS for posting this article.... fantastic. I drove a first generation N54 in a 2007 335i for 10 years and loved it for 200K miles...

I'm considering a 2017 M240i and this article was a great read!!

Also might be advantage to not have the separate HPFP line ( how many did I replace? ) and also removal of PIEZO FI...

More reliable? Less chance of fuel pump failure and injector failure? Both plagued me over my 10 year run.

Any info about pistons, crank, block, rods?

I was interested in 228i stage 1 for track days but there are so many blown engines even in stock form so I'm bit sceptical about that N20. I hope B48 is a bit stronger.

My N20 smokes on start up like it's from the 70's and has since day one. Can't be good.

I've searched this forum (2ADDICTS) for reports of "blown N20" egines and can't find any. If N20's blow up as often as you imply, than one would certainly expect that some portion of 228i owners on this forum would have reported that here, n'est pas?

I'm sorry, I was probably overreacting because I'm really interested in this engine but those threads scared me a lot. Especially because I'm considering used car and I would like to drive it ocasionally on track with stage 1.

I've searched about N20 globally because this one from 228i has probably exactly the same internals as one in first F30 series.

My comments were in response to your comment which implied that the N20 engine could blow "even in stock form". I have found nothing anywhere that would validate that claim. The N20 seems rock solid in stock form.
If you're saying that tuning the N20 well past it's engineering and design parameters, say, over 330 ft/torque - well, that would be a different kettle of fish.

Garage List
He might have been referring to the issue that many N20 owners had with their turbocharger failing around 30,000 miles. Ours did. The compressor side shaft seal failed, causing oil to pool in the compressor housing. This gets invested by the engine on startup, producing copious amounts of smoke, and isn't great for your intake valves either (carbon build-up).
