Whenever I see videos of the engine online its someone doing something stupid like making it output 800hp while doing donuts and burnouts. I love the engine everytime I hop in my mums 335i, like I can just enjoy it, even on the highway it pulls flawlessly and sounds amazing and on back roads even with the constant speeding up and slowing down you can still engage the turbos because it has next to no lag.
I mean people will always tune/mod cars but why to the extent of destroying the engine in 10k miles? I want an e92 335i, its my dream car and always has been since I first drove one but I don’t think there is going to be any left soon.
Because the potential with these engines is fantastic. I know of literally countless tuned N54’s that have done hundreds of thousands of miles & not blown up.
Maintenance is key with them & as long as they’re well taken care of you can easily add more power with a couple of bolt on modifications.
I chip tuned my N54 with the JB4 and did intake, downpipes. Had 204k miles on it when I sold it and got my M4. Only ever had one major issue when the water pump died. Sometimes I would get a few misfires and that would be my cue to change the spark plugs, which would fix the issue immediately.
