M52tu vs m54

There was no "technical update" TU version of the M54 produced, therefore the engine specifications remained the same throughout its 7-year production. Crankcase and cylinder head are made of aluminum.

Compared to its predecessor M52, the displacement of the M54B22 and M54B30 has been increased by a slightly longer stroke of 0. The partially significant increases in output 28 kW in the case of the 3-liter engine were, however, achieved for the most part by reducing the flow resistance on the inlet and outlet side of the engine. According to BMW, the resonance intake system already introduced in the M52TU in was designed to enable a high degree of cylinder filling over a wider engine speed range through a speed-dependent two-stage variation of the effective intake pipe length, thus ensuring improved elasticity.

The variable control of the exhaust valves should also optimize the torque in the lower speed range. The extra capacity is achieved using an increased stroke of There was also a slightly more powerful version of the M54B30 that could be ordered as part of the M Performance package in Canada or the Performance package in the USA. He weighs kg. The main reason for this was the operating design effort and the already almost maxed-out cylinder spacing. This was a further increase in capacity and thus increase performance in the way.

As part of the extensive revision, the design features of the S50 were adopted gray cast iron block, single throttle, double VANOS, exhaust manifold, etc. There was still a slight increase in displacement against the S50B32 from 3.

The cylinder head and the one-piece cylinder block are made of aluminum, with the block used cast iron liners.

So the engine weighs kg. When the piston is forged skirt pistons with connecting rods for high-strength steel connecting rods.

The 5 Most Common BMW M54 Engine Problems

Six high-performance pencil ignition coils with integrated ignition drivers are used for the ignition. The S54 is the high performance equivalent to the M The S54 is technically an evolution of the iron-block S50B It shares few major components with the S50 and differences include:. However, the engine is further modified in order to reduce weight — it features a lightweight exhaust manifold made standard on late models of the normal M3 and thinner exhaust piping.

Additionally, the intake and exhaust manifolds are slightly straightened to improve engine responsiveness. Toggle Navigation. E39 i Performance. Power bhp Top Speed mph mph 9. E83 X3 2.

I would go with the newer E39 which has the M Weight: kg i is somewhat 10kg lighter than i. Maybe the power curve is less aggressive on M52, that is why M54 feels more sporty? Also M52B28TU was restricted in power in the last post I was wrong about the different temperature expansion coefficient of die cast cylinder vs alu. Still marked euro 3 it has the same CO2 emissions. I would like to go with M54, but I feel, I'm missing still some data.

Dear owners, could you, please, advice? Many thanks. I would say the lifespan is about the same. I've driven a m52 engine withkilometers on it. I would go with the M52TUB28 over the M54B25 simply because of the torque specs and the fact that the M52's been around for long time with many miles put on it to test the durability.

m52tu vs m54

Now if you had the choice of M54B30 over that, I would go with that. They're both very reliable engines as long as they're maintained regularly. The only difference is the more torque, weight and materials used. I went from an e46 i to an e39 i.

I found the m52tu a little less exciting, but quieter and better for everyday use.

The torque curve is friendlier and I was shifting its 5-speed less than I was shifting the 6-speed on the i. No issues other than vanos oscillation and smooth In some ways the feel and economy of the newer n52 is more similar to the m52 than the peaky, louder m Note that I also had the zhp version. If I were you, I would try to scoop up a with the M54B30 engine.BMW is held in high regard to their straight six engines, with the M54 being an iconic engine.

They are known to be overall great performers, reliable, and tons of fun. Yet, during my time in the dealership, people were always skeptic about the lifespan of the engines, usually citing horror stories in the shop. A little education on these 5 common M54 engine problems, and finding a technician you can trust, will take them a long way. Change oil every 15, miles and engine is clean. My oil consumption has been very little until recent and it could be the clogged cats.

Creating more back pressure. It drives great again. I love this car. While stories like this may be few and far between, reachingmiles should be attainable for most of these engines if you know what their common issues are.

Taking proper care and being aware of possible issues will ensure a long and well traveled life to you and your BMW. The cooling system, specifically the thermostat and water pump, are notorious issues in most BMWs.

Now this is nothing to fret about, as they should be lasting anywhere from 60kk miles. If you notice your car running hot, running out of coolant, take it in and have the pump checked. DIY: I would consider it to be an intermediate level DIY, and here is a video for the install to see if you can do it.

It is an intake adjusting unit. It looks like a small black box, but you need to know when it is going out. Why is it important to know when it is about to go out, and not just wait? So take a listen and if you hear rattling, take a moment to check it.

I replaced the engine and cooling system, and the car is running great. Having nothing left to fix I've been trying to figure out what BMW did with these aluminum blocks.

I've read that the M52TU used an aluminum block with iron sleeves. This sounds good to me. I haven't been able to confirm if this was through the end of production for all M52TU engines or if this design was carried over into the M54 engines.

Can anyone shed some light on this? Become an Inner Circle member to remove these ads. Remember the Vega? It, too, had one, and it had overheating and oil-consumption problems, as I recall. Ed in San Jose. Golden Gate Chapter. Aspensilber over Aubergine leather.

Craig in Canada. Does that mean that the all-iron block M52 doesn't have the same sensitivity? I haven't seen it discussed in this manner before. It's always generalized into "I6s are sensitive". I'm more concerned with engine longevity as far as normal wear.

The overheating sensitivity is due to a few things, such as the aluminum alloy used in these blocks and the cooling system design which routes most cooling flow into the head rather than through the engine block. The valvetrain is very solid in these engines even when neglected. I've never seen wear on a 24v camshaft, even in one extreme case where an oil passage had been blocked by sludge and the cam seized and broke in half.

That was clearly a high mileage, neglected engine, but the load bearing surfaces in the top end still looked great. Same goes for the bottom end. BMW figured those out a long time ago. They'll last forever if you change the oil and run the motor gently until the oil is warm. The one area I can see as a potential weakness is the cylinder walls. Plated aluminum doesn't last forever. I feel better about steel sleeves.

The engine I put in the car has a "98" casting date, and came out of a 99 i.Valve supplied without a spring. The spring is necessary to take out the old valve.

BMW plant is not sold separately, but only in the assembly with the oil filter housing. Remove the air filter, remove the generator insulation of a positive wire. Unscrew the oil filter housing with the power steering pump. Disconnect the connectors from the pressure sensors and oil temperature.

Remove the old valve. Remove the spring and keep it. The new valve without the spring. Install the spring in a new valve. Wash the body of the Deposit and balance valve should be purged. Repair the oil filter housing BMW full. Putting it in reverse order. Whereby the oil valve Cup bmw is stuck open, the locking part gets crooked and the oil begins to flow out of the Cup after the cessation of engine operation.

As a result, when the engine heard the distinctive clip-clopping sound and on the dashboard there is a red oiler. Such failure is very dangerous for the engine, it misses in a timely manner a sufficient quantity of oil, as it takes a lot of time until the oil pump nakachatsya in a glass and gets into the engine.

In the end, the start of the engine is converted for the owner into a repetitive nightmare. If you do not pay attention to this fact, then engine damage is imminent. The valve Cup m54 performs the important function of holding a glass filled with oil when the engine not running, thereby draining the oil cavity of the oil filter.

Such failure of the check valve x5, non-return valve X3 and other BMW models were corrected only for the acquisition and replacement of the entire oil filter housing. Our company began to produce the alternative — himself-off valve or check valve m54, m52tu, m52, m50tu. Check valve, X5, X3, etc. Valve replacement on new sufficient to ensure that the problem was resolved and forgotten.

The M54 and its stuff is lighter, so that might account for part of it. Other than than the steptronic might have higher ratio diff so that would also the car eat through the revs a bit faster. Anybody know the times from idle to limiter when revved in neutral? Years ago Toyota Corolla adverts for twin cam motors claimed less than one second if memory is correct. If it's mainly down to the restrictive intake then will an M50 mod completely change it's character?

Ok Moranor I think! I know you're right, I'm just loving the low down kick. Is this case true but not always, as the M52's that came in the e46 had double vanos. The M54 engine in our E46 i is a real gem! Very lively and sounds great! Smilies [ get more ] [ photobucket ].
