I do keep an auto trader search open for 35is from 2015
for this reason….
I think the N20 variants from 2015 had similar internal revisions like timing chain guides etc.
The N54 internals were only changed early on prior to E89 production…the number of the bolts holding the flywheel was changed…
There were a myriad of changes to injectors, HPFPs, coils but that’s it…all N54s in all models were essentially identical..
The N20 did have revisions as stated to cam chain, tensioner, oil pump drive and later Euro 6 injectors ..those weren’t used on E89s…as I found out after several weeks of head scratching…
