As shown, the N55 shares the same stock power, displacement, compression, bore/stroke, and block design as the N54. Thank you. Hi All That said, the N55 seems to be slightly better than the N54 with regards to carbon build-up. Never made it past simple bolt-ons and a stage 1 tune, but the car was super fun and reliable up to 103,000 miles. Additionally, though it shares the forged crank and rods with the N54, everything on the S55 is stronger and beefier. The cap leaking does seem to be a part of the cause.

Soooo if you have some noise under load best record it from engine bay. However, a couple quick notes that are imperative to keep in mind: B58 engine reliability BMW engineers were able to resolve the main issues with the engines that preceded the B58, including: Updating the fuel system Modernizing the cylinder head They fixed issues with the particulate filters A fresh design for the timing chain In 2010, the 335i received the updated N55 engine followed by the B58 in 2016, however, the model was rebranded to the 340i.

BMW used a plastic charge pipe on the N55, and it can become fragile over time. My question is what are the running costs for them (a ballpark mainly). Hello, I own F20 120i 2018 with B48 engine (184hp). My regret (not even a problem) was that when moving from E to F, BMW matched gearboxes and diffs more closely to stock engine torques, which in my mind was a bit of step back, because you could always count on 3 things with BMW gearboxes in the past 1. they did not provided greatest feedback 2. they always had decent of headroom potential tune 3. every-time you changed gear you felt like you reloaded WW1 full caliber rifle. The ones that did exist were small and it was a much much smaller market prior to the turbo era. Had the well known gasket issues. About heat capacity of water / glycol. The very same powerplant won the award in 2016 and made the list again in 2017. Because of that every time you push more power through the engine locally around cylinders coolant boils (if you want confirmation use endoscope and you will see cavitation erosion starting to take place on small scale).

Only tool I needed was a small flathead screwdriver. Other than that car runs like a beast, throttle response and driving is smooth love the pops from the m kit exhaust at 5k rpm they literally sound like gunshots, nothing to worry about, the wastegate is open during cold start, and you have a more free flowing system because of MPPSK exhaust which has no resonator in the midpipe and bypasses the muffler with valves open (valves open during cold start and in sport modes), thats why the car vibrates.
