BMW N51 VS N52 The N51 and N52 are essentially the same engines, and it’s almost impossible to tell the differences visually. The easiest way to know what engine your car is equipped with is to check the emissions label under the hood. The N51 will say “SULEV”, while the N52 will have “ULEV”.

Is the N52 a good engine?
With durability and lightness as the engine’s trump cards, the N52 was an exceptional replacement to its predecessor, the M54. Being light meant better weight distribution, and with the addition of double electronic variable valve timing, these engines could produce upwards of 260 naturally aspirated horsepower.
How much horsepower does a N52 engine have?
The N52B30 was produced from 2006 up until 2015 in as many as seven engine tunes. This 3.0L iteration was the more popular and longer-running version of the N52. Peak output varied from 215 hp to 268 hp, and peak torque was anywhere between 199 lb-ft and 232 lb-ft.
What kind of engine is a N52?
The BMW N52 is a naturally aspirated straight-six petrol engine which was produced from 2004 to 2015. The N52 replaced the BMW M54 and debuted on the E90 3 Series and E63 6 Series. The N52 was the first water-cooled engine to use magnesium/aluminium composite construction in the engine block.
How can I make my N52 faster?
Simply replacing the intake manifold with the OEM 330i intake manifold will take any N52 into the 250hp ballpark. As such, 325i models may pick up 30-35hp and 328i models may see gains up to 20-25hp. It’s also a direct bolt-on upgrade since it comes directly from an N52.
Can you put a turbo on a N52 engine?
So to place a turbocharger on a E9x N52, a custom exhaust manifold/plumbing is required. A low rear exhaust manifold is possible with a ‘small’ turbo. A top mount turbo is ‘easier’. BPC and DigiDon both did this.
Can you supercharge a N52?
ESS is proud to offer the newly developed Gen. 3 E-Charger G1 based supercharger system for the BMW N52 engine family. This supercharger system is designed to offer the customer a very quick and easy, 100% bolt-on installation. With this supercharger system we bump the power output by 80-100 horsepower!
How much oil does a BMW N52 take?
The oil capacity of the N52 engine is 7 quarts, which is what mine gets each oil change, along with a new filter. Keep in mind if you purchase oil from BMW, they now sell it in liters, not quarts. 6.5 – 6.6 liters or 7 quarts.
What is the difference between N52 and n52n?
Most significant differences are: New engine management, new HFM (digital), new throttle, plastic valve cover with integrated crank case vent valve and oil separation, stronger connection rods,exhaust valve stem increased, new electric water pump and lightweight camshafts.
Can you swap an N52 for an N51?
It would work just fine as a 1:1 swap.
How do I know if my engine is N52 or N53?
As per the N52, the N53 has double-VANOS (variable valve timing) and a magnesium alloy block. Unlike the N52, the N53 does not have Valvetronic (variable valve lift), due to space limitations in the cylinder head. The bore of 85 mm (3.35 in) and stroke of 88 mm (3.46 in) are the same as the N52.
How do I know what N52 engine I have?
The rear-wheel-drive 328i is powered by a 3.0-liter inline-six that makes 230 horsepower at 6,500 rpm and 200 pounds-feet of torque at 2,750 rpm. While the engine doesn’t have the low-end thrust of the twin-turbo 335i and its unique 3.0-liter inline-six, it is smooth and flexible.
Which BMW engine is the most reliable?
- BMW B58 Engine.
- BMW M20 Engine.
- BMW M50 Engine.
- BMW S62 Engine.
- BMW N52 Engine.
- BMW M54 Engine.
Does the 328i have N52?
The easiest way to identify which engine you’re dealing with is to take a gander at the vehicle emissions plate under the hood. You’ll notice the relevant info on the left-hand side of the plate in the third row. N52 will be marked as LEV, while the N51 carries a SULEV tag.
Does N54 manifold fit N52?
The N52 engine in the 328i is a naturally aspirated 3.0L inline-6. It uses a lightweight magnesium & aluminum block to help keep weight off the front axle.
How much horsepower does a n51 have?
So it seems that although the n54 and n52 manifolds use the same gasket part number and bolt pattern they are not perfectly interchangeable. N54 has more square ports and n52 more ovalled, plus the locations of where the runners meet the head is slightly different.
Whats the difference between N52 and N54?
engine is SULEV II compliant with 230 horsepower.
Can you put a supercharger on a 335i?
Compared with the naturally aspirated BMW N52 that it replaced as BMW’s highest performance six-cylinder engine, the N54 produces an additional 34 kW (45 bhp) and 108 N⋅m (80 lb⋅ft). The N54’s direct injection system (called “High Precision Injection” by BMW) uses piezo injectors.
What brand of oil does BMW recommend?
You would have to replace so much to put a supercharger on the 335i. You would probably spend less on the single turbo kit… Also remember that the tuning is different so that’s gonna need to be dealt with too. And in the end you’re gonna have less power than the single turbo guys.
Should I use 5W30 or 5w40?
The BMW branded lubricant formulations are based on Castrol EDGE, a leading full synthetic brand strengthened by Fluid Titanium Technology which increases film strength, reduces friction, and improves lubrication under the intense pressure of high output engines.
Can I use 5w40 instead of 5W30 for BMW?
Although both have the same viscosity grade in cold weather, 5W-40 is thicker than 5W-30 at warmer temperatures. It’s also worth pointing out that: 5W-40 is the suggested oil for most diesel applications. Rarely (if ever) do vehicle manufacturers recommend putting 5W-40 oil in a gas-powered engine.
Is BMW N52 direct injection?
BMW says you can use an: 0w40, 0w30, 5w30 or a 5w40 LL-1 oil in the USA. Btw… you can also use a LL-4 rated oil where a LL-1 oil is spec’d, but not vice versa! Maybe who ever changed you oil put too much oil in the engine.
What is the difference between N52B25 and N52B30?
One major difference with the N52 is that it comes with High Pressure Injection, which is basically direct injection.
What is a N51 engine?
The N52 came in two flavours: the N52B25 used a bore of 82mm and stroke of 78.8mm with an 11.0:1 compression ratio, while the N52B30 used an 85mm bore and 88mm stroke with a lower compression ratio of 10.7:1.
How do I know if my 328i is SULEV?
The N51 has a lower compression ratio and a different piston design. It also has an extra catalytic converter, a PremAir radiator, and a secondary air pump. The output of both engines is supposed to be the same.
