Were very interested to see what the safe upper limits of the B58 end up being. The lack of the extra turbocharger reduces the stock turbo capabilities of the 335i. Experience something very similar with a 2018 M240i. The ML variant makes 335hp while the OL features a staggering 382hp. 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. Did this fix the problem? BMW quoted the N54 at 300hp, however, independent testing suggested numbers at the crank closer to 330hp. Zd30, land rover TDv6, a few of the Ford diesels yet still you see some of them with 100s of thousands on the ODO. Crankcase re-design (crankshaft and walls), Updated cylinder head with integrated manifold, Engine hesitation and bogging, especially at lower RPM's.

DIY the basics (oil, brakes, spark plugs, etc) $500 to $1,200 a year I have also speculated that it could be a throttle-by-wire issue where the interpreted throttle value is not constant (maybe its me thats not constant!!).

Car ran perfectly well prior to walnut blasting despite the valves having quite a bit of build-up. Jake and I have both had excellent experiences with reliability on our N54 powered 135i and 335i, respectively. Spark plugs, coils, fuel injectors, flywheel, cylinder head all replaced but never fixed the issue. So much too learn, so little time. Love the car but hate the pain! It also comes down to each specific engine. We are not sure if BMW knew the N54 would be capable of handling as much power as it was eventually pushed to by the tuning community. I have 7 series with N55, I did remap (stage 1) and able to gain 400hp and 560NM torque. Trust me she still has a lot of life yet to go.

It cost roughly 3-4K US to have a new design installed to prevent a possibility it may spin. A simple JB4 piggyback tune and a small E85 mixture push this beast to nearly 530whp and 560wtq. . You can indeed tune an M340i without voiding warranty. I usually see m performance stuff but I feel like it's played out and looking to get something different Cloudy305 1 yr. ago Its a superior design for strength but theyre often more challenging to cool. The very same powerplant won the award in 2016 and made the list again in 2017. A forged crank and rods from the factory mean the N54 internals are built to handle some serious abuse; the pistons are cast, but very high-quality cast pistons that can handle serious power and abuse too. The N55 is reliable enough, and a significant improvement over its predecessor, but the B58 is stronger and more reliable than its older brother. Anyone here want to offer an opinion?
