Hey everyone,
this is my first post on here so I apologize if I am posting in the wrong section or beating a dead horse.
I am currently in the process of rebuilding the N54 out of my 2008 335i. The engine spun a rod bearing, and the cylinder bores were too worn to be reused with standard-sized pistons. The rod journal on the crank for the spun cylinder was also pretty marred up. Because of this, I decided to purchase a good used block with cylinder bores in spec, and a nearly perfect 6 bolt crankshaft so that I can use the 335is clutch and flywheel. My plan is to reuse 5 of the stock piston-rod assemblies and purchase an OEM connecting rod used on eBay. I intend on using standard King main and rod bearings, however I have not decided between ARP and OEM main studs, head studs, and rod bolts. Aside from the plans I have mentioned, I have no idea what I should change while I have the engine apart. The water pump looks to have been upgraded to an all aluminum unit, however I do not know the condition of the HPFP or injectors. Aside from basic maintenance items, do you guys have any recommendations for upgrades while I'm in there? Also, I would appreciate any tips and tricks for building an N54, as this is my first time dealing with an overhead cam engine (I'm used to pushrod V8s).
Thanks!
Jack
