I want to see this!

So 328 is the turbo 4. 330 is NA i6 and 335 is turbo i6? I didn't know they made a 330 now.

Not quite.

For the E90 generation:

• 325: 2006 only, N/A 2.5L I6
  
• 330: 2006 only, N/A 3.0L I6
  
• 328: 2007+, N/A 3.0L I6 with more restrictive intake manifold
  
• 335: 2007+, Turbo 3.0L I6
  

For the F30 (current) generation:

• 320: Turbo I4
  
• 328: Turbo I4, makes more power via different compression and tune
  
• 330: Turbo I4, new engine vs 328 but same power rating (ish)
  
• 335: Turbo I6
  
• 340: Turbo I6, new engine vs 335 but same power rating (ish)
  

Saw this thing in person last night and it's clean! Excited to see it all done up. Good that the belt tensioner is being done - check the oil filter housing gasket for leaks as well. Beyond those two points, the N52 is pretty tough.
