Bmw n54

When you think of robust straight-six engines that have the potential to make a lot of power, what do you think of?

Back inBMW launched itself into this category with the release of the N54 engine. Since this motor shipped with forged internals, a few mods can reveal insane power. With an upgraded twin-scroll turbocharger and a few bolt on modifications, an N54 can put over HP to the wheels.

Check out Chad Rose's driveway-built xi that should be running in the 10's this season for a good example of this.

This guide is drawn from both personal experience and two years of extensive research. All the info here can be applied to the following Nequipped vehicles:. The BMW N54 uses an electric water pump instead of the typical chain or belt-driven mechanical water pump. The electric water pump has a lot of benefits over the mechanical variant. It warms the car up faster in the cold winter months. It keeps running after the engine is off to cool down the turbos after a spirited drive.

Also, because the engine isn't running the water pump, it ever so slightly takes stress and load off the engine making it more fuel efficient and powerful. Diagram Parts List. Expect to replace the water pump every 60, miles, and the thermostat every other time you replace the water pump. Luckily, these aren't too expensive. On multi-port injected cars, gasoline is constantly shooting on the intake valves.

Gasoline is an excellent solvent, so it keeps the intake valves clean. BMW recommends walnut shell blasting the intake valves every 40, miles. The high-pressure fuel pump is another common failure item with the N The high-pressure fuel pump pressurizes fuel toPSI so that it can be injected into a fully-compressed ignition cycle and atomized properly.

A recall was issued by BMW, and they extended their warranty on the fuel pump for ten years ormiles. For owners that have overmiles, the HPFP is not that difficult to replace, and the pump isn't overly expensive. Injectors are one of the more common failure items. They've had over ten revisions, but are still known to fail. We recommend a non-genuine component, which provides the same functionality and reliability as the genuine components, just without the price.

The oil filter housing gasket is a known gasket that can leak on the N54 powered cars. The gasket itself is cheap and isn't too tough of a job if you're familiar with working on cars. If you have a leak from here, this is one gasket I'd recommend replacing immediately. When the N54 shreds a belt, you're going to have a bad time. There have been stories of belts getting sucked all the way into oil pickup, causing the timing chain to break, resulting in catastrophic engine failure.

There are two ways that this can happen. On mid and newer models, BMW included a notch in the subframe to account for this issue. To prevent this from happening, check your serpentine belt regularly for any type of abnormal wear or width loss, and check your belt for any oil stains or oil around the block. Also, it's advised to change your belt every 15, miles as preventive maintenance.

The belt is easy to replace if you have the right tools. If you have an early build model, you can upgrade your motor mount to the is version. Also, when you pull your coils, you will see oil pooling in the spark plug holes. The easiest way to tell if the valve cover is cracked is to check around cylinder 2 and 3 for oil seepage, or you might even be able to spot a crack visually.The motor is based on aluminum block of cylinders which is equal to M54B30 with cast iron sleeves.

It also has newly developed cylinder block with direct injection Double-VANOS variable valve timing on the intake and exhaust camshafts system.

Diameter of inlet valves is Boost is implemented with the help of two Mitsubishi TDTK3 turbo chargers which operate in parallel. Every turbocharger is in charge of its 3 cylinders from the block. The N54 engine has a boost pressure of 0. At the same time this motor could also be found under the bonnet of Alpina autos.

They were modified and improved in order to perform HP. Alternative to N54 engine appeared in This is the time when bavarian engineers introduced their new turbocharged 6-cylinder N55 engine N55B At the same time N54 is still being produced by the company even nowadays. N54B30O0 — is a base modification with the following specs: Power — HP at 5, rpm, Nm of torque at 1, rpm. It was used for BMW models with 35i index. It differs from stock version by fan, radiator and ECU.

The main difference of this version is in improved cooling system radiator and fan as well as ECU. Sometimes problems of white smoke may also occur.

This is when you need to check the coolant level which is the main cause of such problem in the majority of cases.

The same duration term is for water pump and turbocharger. Abovementioned figures also depend on level and type of usage. Summing up we can say that this engine is rather reliable and powerful. Owners will hardly face any problems. At the same time this motor has high level of durability and long lifespan. In addition it is the best bet for those who like different tuning experiments. This is why BMW N54 is one of the best engines ever produced by major bavarian automaker.

You will not face any difficulties while upgrading your N54 engine. At the same time its modification will not cost you a fortune. Stage 1 firmware will provide you with up to HP. If you need to increase this rate to HP, you need to modify cooling system replace in fans and installing additional radiator.

At the same time you also need to buy large intercooler as well as air filter.

This is the best bet when it comes to tuning of BMW N54 engine. It combines power, availability and lifespan. If you want to bring the level of power up to HP, you will need to install Methanol Injection Kit.

N54 FBO Stage 2 firmware will make it possible to cover quarter mile in Big single turbo kit along with cylinder block head porting will provide our engine with maximum power. You will benefit from wide range of different components. You can use Alpine B3 S Biturbo head gasket in order to reduce compression ratio. The N54 engines stock internals are able to handle with HP.

Mitsubishi 4G Honda K20A K20C.

Turbocharging is a key difference between the N54 and BMW's previous straight-six engines. The N54 has two small low-pressure turbochargers to minimise turbo lag. BMW's marketed the twin-turbo as "TwinPower Turbo", [10] although the term has since been used for engines which have a single twin-scroll turbocharger. Its N55 successor uses solenoid -type injectors, because the piezo injectors are more expensive and not reaching their full potential to obtain the "lean burn" benefit.

DIY Modification Writeups, discussion, and photos for doing it yourself.The BMW N54 engine featured in the i, i, and i is one of the most tune-able engines ever.

The N54 engine has forged internals, meaning it can handle an immense amount of power without requiring any expensive engine modifications. BMW rates the engine at hp and tq to the crankshaft directly out of the factory. It is widely known that BMW undershoots their power estimates, and this is especially true with the stock N54 putting down roughly hp and tq to the wheels! This guide will take you step-by-step on the mods necessary to build a hp i, i or i.

Horsepower is created from combustion. So to make more horsepower you need more combustion. This means that the car needs to pump more gas into the combustion chambers to create more horsepower your mpg will go down, yes. As a result, gas is left in the engine and then can pre-detonate, or cause misfires due to the high temperature levels in the engine. Before shooting for significant horsepower gains, you should change your spark plugs! But which spark plugs should you be using?

The OEM spark plugs are great, but only if you are running stock boost levels. More boost causes for more fuel, which creates more combustion, which creates higher engine temperatures! These higher engine temperatures are what cause pre-detonation and misfires. Spark plugs have heat ranges which control the temperature that they ignite at. Using a colder spark plug will reduce engine temperatures and prevent misfires and pre-detonation caused by burning more gasoline.

Ignition coils should be replaced every time you replace your spark plugs. Ignition coils power the spark plugs — bad coils can cause the same problems as bad spark plugs so it is important to replace these as well. Check out these guides if you are already FBO and looking for the next step! Dual cone intakes are an essential upgrade for your N54 if you are looking to further tune and modify your car. This was the first mod Zach and I put on our cars, and it is, in my opinion, one of the most necessary supporting mods for breaking hp.

Aside from additional horsepower, you also get an awesome and aggressive engine sound that is intoxicating.

If you are unsure of which dual cone intake is the best for you, you can read our tuning guide on intakes which lists all of the available options, their prices, and horsepower gains.

Zach and I run the BMS intakes, and are more than pleased with the results. Second on the list is a set of catless downpipes. The catalytic converters on the OEM downpipes are very restrictive, and limit the amount of airflow leaving the engine. This becomes an issue when we put a tuner on our car and increase our boost pressure psi. With catless downpipes, you will be able to run more air through the turbo system which results in higher boost pressures, and better spool times.The motor is based on aluminum block of cylinders which is equal to M54B30 with cast iron sleeves.

It also has newly developed cylinder block with direct injection Double-VANOS variable valve timing on the intake and exhaust camshafts system. Diameter of inlet valves is Boost is implemented with the help of two Mitsubishi TDTK3 turbo chargers which operate in parallel.
