|BMW N54 engine|
Very very different engines – N52 is actually the more advanced design, lighter with magnesium and aluminum constuction, N54 is also a 2 piece design, but an all aluminum engine, so block, heads, intake, pretty much everything is different except some of the accessories that bolt onto it, like the electric water pump, …
The 2JZ-GTE rolled out of the factory with incredible strength – beefy forged crank and rods, oil cooled pistons, and an iron closed-deck block. While the N54 is no slouch, the 2JZ is definitely the stronger and more durable engine between the two.
The top speed of the 328i is an electronically limited 130 mph. The 335i is significantly faster to 60 mph, as it performs the highway-speed sprint in 5.1 seconds with the auto transmission or 5.4 seconds with the optional manual. The 335i shares the 328i’s 130-mph top speed.
Stock N54 Rods, Bearings, Pistons (600-700whp)
Most blown N54 motors begin with the pistons, rods, or rod bearings. The rods are forged, however pistons are not. N54 rods are strong, but they’re not indestructable. … Then again, some rod bearings seem to hold lots of power for 200k+ miles.
The 135i is faster, but not by much. There is about a 200-300 lb. difference between the two. I think the 135i is significantly cheaper as well.
Turbochargers on the BMW N54, for the most part, last around 100,000 miles before they have to be rebuilt or replaced. It isn’t uncommon to hear of cars that have the original turbos still functioning as designed upward of 200,000 miles.
2007 BMW 335i (E Chassis, N54 Engine)
2007 marked the introduction of the 335i model which was the first BMW to feature the N54 engine. As the earliest model year the 2007 335i generally suffered the most issues of all 335i’s early on. The HPFP and fuel injectors were the two big problem areas.
The process is zero-hassle from the moment we… Buy the completely remanufactured BMW N54 engine for $3,495 that includes a two-year, unlimited miles, parts, and labor warranty. Ghassan Automotive wants to provide a stress-free and convenient experience.
Generally, the 3 best bolt-on engine mods for the N52 are headers, the 330i 3-stage manifold, and a tune. These mods alone will likely put the N52 in the ballpark of 270-280 horsepower.
One major difference with the N52 is that it comes with High Pressure Injection, which is basically direct injection. But the N53 does not have Valvetronic because there is not enough space in the cylinder head to implement both direct injection and Valvetronic.
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.

3.0-liter I-6 engine
The 1M is powered by the N4 twin-turbocharged 3.0-liter I-6 engine. For the 1M, the turbocharger, exhaust system, and ECU have been revised to produce 335 horsepower and 332 pound-feet of torque, though up to 369 pound-feet are available temporarily in overboost mode.

The BMW N52 is a naturally aspirated straight-six petrol engine which was produced from 2004-2015. 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.

As long as your tune is on point and you are not doing anything stupid, 99% of the time, you are using the N54 as a low-compression NA engine, which should last 300, 400 or even 500K. From everything I have read, there are no internal weak spots with these engines, just weak peripherals.
Regular fluid changes. Downpipes Intake and intercooler will all make the turbos work a lot easier and more efficiently. A proper tune and besides that, you should be prepared to change spark plugs and coils if misfires occur. N54 is pretty reliable besides a few misfires on old hardware.
The N55 can handle around 550whp and 550wtq on the stock engine block and internals.
Basically a stock N54 runs its turbos at ~8 psi & dynos @ 270 WHP/280 WTQ. On a FBO (Tune, Intake, FMIC, DPs, upgraded CP + DVs or BOVs to withstand increased boost) N54, the turbos are good for 18 psi & 370 WHP/410 WTQ. With meth, you’ll be over 400 WHP easily.
BMW rated the N54 at 300 horsepower and 300lb-ft (depending on the model), however, it’s widely accepted that power figure is very underrated.
