no component sharing between “M” car engines and “noraml” car enines. the N62 does not share any components with the N73 either. the N52 and N54 do not share. basically turbos and N/As dont share.
the N62 has had a couple displacements based on the bore. these came along with the N62tu update. now there is only the N62TU wich is the 4.8. the 4.4 (N62)is being produced anymore.

You give a lot of very interesting information (and pictures) but you tease with little subtopics! "It’s a very ingenious design for many reasons." But--- what are the reasons? Also, how does the N62 accomplish it's different displacements? Is it bore, and uses this to accomodate turbocharged versions? Also, Does the N62 share block or components with the M3's S65 "They do not use Valvetronic. It is redundant due to the naturally more efficient charged air intake". I can see there being less of a need to use this to optimize the intake resonance, but there is still a need to optimize the amount of air coming in. Wouldn't there be huge variances in intake pressure given the turbo? Also... what about the watercooling of the turbos? Is it a separate air-water intercooler or is the compressor jacketed somehow? Sorry... a lot of questions :) Thanks for your time and effort in these articles! Al, thanks very much for the article, it’s interesting indeed.

“It’s a very ingenious design for many reasons.”

But— what are the reasons?

“They do not use Valvetronic. It is redundant due to the naturally more efficient charged air intake”.

The N52 3.0L or the N54 3.0L turbo? I only ask as I was reading a debate on this over at bimmerfest. Personally, I like the idea of the naturally aspirated N52, despite it's lack of punch compared to the N54. Al – Which engine would you say is better to own? The N52 3.0L or the N54 3.0L turbo?
