n54 vs n55 internals

However, knowing the BMW tuning industry as we do, it’ll only be a matter of time before there are similar tuning packages available for the N54’s replacement.All rights reserved © 2014-2020 Drive-MY EN/UK. Basic maintenance/repairs for STOCK N54s: 1. Let’s examine what is new with the BMW B58 engine and what the differences are between the N55 and B58 engines. 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. We’ve been seeing hybrid turbo upgrades for the N54 for a while and these can give you an improvement in power. It pushed out 335hp and 332lb ft with an overboost function for even more performance for short stints. The reason for using a single turbo is purely for efficiency – 15% better fuel economy and lower emissions, which are helped by the introduction of Valvetronic variable valve lift technology (not fitted to the N54).
Where the former used two small turbos, the updated engine used one larger one, which features a twin-scroll compressor housing. Follow him on Instagram for more 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. 4. This conversation came up at a party I was at. This means that they have an identical bore and stroke (84x89.6mm), and the compression ratio is the same too at 10.2:1, which goes a long way towards explaining why it drives so much like a normally-aspirated engine. Even alone these can help the turbos spool up quicker and a gain in power will be seen.It’s when coupled with a remap or piggyback ECU (JB Tuning and Vishnu are very popular choices for these, with packages from around £185-£520 depending on what features you need) to increase the boost with fuelling and timing to match, the results are pretty incredible.

Upgrades from Forge and Turbosmart resolve this issue for around £220. Though the magnesium-aluminium material is great for weight saving it was deemed to be too weak so BMW opted for the more traditional approach of using all-aluminium with cast iron cylinder liners.
This is in place of the air-to-air intercooler found on the N54/N55. With a big single turbo, you can push both engines to around 600 to 700whp on a stock bottom end. 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 The water pump is also electric on the N54 whereas on the M54 it’s cast into the front of the block.

Because this only requires one turbo, which is more efficient and cheaper, it’s a good option – the pay off being turbo lag, though this is still relatively minor.

I finally replaced them all and it is running really well now, but 168,000 on it.
