I finally replaced them all and it is running really well now, but 168,000 on it.
The 36 month/36,000 mile warranty is honored at over 10,000 service centers across the country. so basically im stuck between getting a 2009 bmw 335i with n54 motor or a 2010+ bmw 335i with n55 motor.
BMW proved it could build successful turbocharged petrol engines with the 1973 2002 Turbo, though after that there were very few uses of forced induction for its road cars.
BMW were successful in their aim – the N54 drives more like an enhanced normally aspirated engine than an out-and-out force-induced motor.The N54 saw a small revision in 2008, upping power from 306hp to 326hp and torque from 295lb ft to 332lb ft. Its ultimate guise was found only in the 2010 E82 1M Coupé – labeled the TO version. 07335. However this is more for the tuner inclined group of people amongst--what exactly is the "roadblock" of the N55 that, currently, as it stands, not nearly as much support is given to the N55 compared to the N54. There are plenty of competitor products to look out for, too, including AWD Motorsports and RB.Beyond hybrids, you’re looking at the world of big turbos.
They provide 2JZ-like levels of performance, respond very well to modifications, and have strong aftermarket support.Two of the most popular turbocharged BMW engines are the N54 and N55. The restrictive point of both the N54 and N55 engines are the downpipes. I was initially set on the N54, but after doing more research I don't know if I want to take a chance with its reliability if the N55 is also capable of supporting my power goals (around 400 rwhp with turbo upgrade).
As well as this, the M54 used a more traditional fuel injection method, whereas the N54 features state of the art direct injection.Designed to drive like a normally-aspirated engine, the N54 has a relatively high compression ratio for a turbocharged engine at 10.2:1. They’re very similar and closely related, but there are some significant differences. its bad that its cast compared to forged n55 internals, i know its better design but... in the end forged takes more abuse !!! The N55 produces 302hp and 330lb ft of torque in standard form or 315hp and 330lb ft in its High Performance (HP) variant.The N54 and N55 share their internal dimensions with the engine they’re based on: the M54. This means that the exhaust-side of the turbo is divided into two parts, each fed by three exhaust primaries each. Still, love the N54 motor, kind of like a modern 2JZ motor. Archived.

The water pump is also electric on the N54 whereas on the M54 it’s cast into the front of the block. Being so similar, the process is the same in essence: by getting gases out of the engine faster and increasing the boost big improvements in output are achieved.
good but i am sure ive seen cars post 2014 engines holding 16+ psi till 6.5k rpm Whether your N54 is stock or running a large single turbo set up, this guide will ensure your engine is running at its best. Time for new.both engines produce a claimed 300 hp therefore stock power is equal.BMW factory HP ratings are figments of the marketing departments imagination.2017 BSM M2|6MT|Exec|black kidneys and gills|full alcantara wheel|CF spoiler|Dinan Stage 4|Dinan COI|Dinan free flow exhaust with resonator delete|Fabspeed sport cat DP|BMS clutch stop|465 bhp|4.75/5 stars 08-03-2016, 06:40 AM. Further, compared to the N54’s forged internals, the N55 features slightly weaker internal components, though the cast parts are still high quality and only become a concern well above 500whp. Whatever the case, I have owned 2 N54 vehicles and the fueling problems along with the turbo failure and unreliability after tuning made me walk away. You're modifying your car, so the N54 is the way to go. Common issues for the N55 include valve cover leaking, electronic water pump failure, high-pressure fuel-pump failure on older models, and VANOS solenoid failure.Both engines suffer from waste-gate rattles, however, it doesn’t typically affect the longevity of the turbos.To put it simply, the N55 is more reliable than the N54, but that’s not a hard thing to achieve considering the N54 was pretty unreliable.I know there are going to people in the comments claiming their N54 or N55 is the most reliable thing in the world and has never broken down on them, but the reality is that both have pretty poor reliability, with the N55 being marginally better.When it comes to internal components, the N54 is arguably better.
