S54 engine

It featured individual throttle bodies, variable valve timing, horsepower, and an 8, rpm redline. But like most race bread engines designed for street use, they had their own problems…especially as the mileage accrued. With our Project M-Track3rwe unfortunately succumbed to the latter. Our M3 was beyond the year range of which most rod bearing failures occurred. We took our M3 out to Streets of Willow at Willow Springs and on the last session of tire testing, fell fate to that notorious knock.

We enlisted the help of Formula Drift champion Michael Essa and his shop Essa Autosport to overhaul our sad straight-six. He has successfully ran his S54 engine for the last two years of competition without needing a rebuild…all while making around 1, horsepower to the rear wheels.

These engines need to be treated like a sports car engine and not like a Honda Civic. The Build. These bearings also feature chamfered oil holes. We step torqued the mains up to a final value of 60 ft-lbs.

Left Luckily our stock crank wasn't damaged and a simple micro polish returned it to new. Right Essa step torques the ARP main studs to a final value of 60 ft-lbs. The unique construction comes standard with their proprietary connect rod bolt design. The material is sourced from a special blend of chromium, nickel, vanadium, and molybdenum-forged alloy. Connected to the Carrillo rods are a set of JE Pistons stock compression ratio pistons.

Since we are running our E46 on only 9 psi of boost, we wanted to minimize the torque loss from a lower compression ratio piston. The FSR forged side relief asymmetrical forging keeps the skirt panel width where it needs to be wider on the thrust side of the bore to minimize weight and friction. Even though these pistons are stock in compression, the alloy pistons can handle over 1, horsepower if we ever wanted to push it that far. Essa installs the JE rings onto the JE stock compression ratio asymmetrical pistons.

He conjoins the Carrillo rods and installs the pin and clips. Finally, a ring compressor allows the assembly to slide down into the bore. Featuring a. This organic base head gasket utilizes a metal cooper ring for each cylinder. Affixing the stock cylinder head and valvetrain to the block is a set of ARP head studs, step torqued to a final value of ft-lbs.

The stock cylinder head and valvetain work great from the factory. Though one bit that we wanted to upgraded was our valves. We hooked up with Ferrea for a set of its stock diameter intake and exhaust valves.While the S54 is the big brother to the M54, it was actually built and improved off of the S50 engine, its predecessor from the E36 M3.

Compared to the S50, the S54 was increased to 3. The roof, trunk, and body panels were all made of either plastic or polymers reinforced by carbon fiber, in addition to a number of other carbon fiber inserts such as the door panels, console trim, etc.

These versions of the M3 also came with a carbon fiber front splitter and rear diffuser. The HP engine had improved camshafts, a bigger air intake with a carbon fiber manifold, an improved exhaust manifold, and upgraded exhaust valves.

The engine improvements resulted in an increase in horsepower and torque to HP and lbft. From a reliability perspective, the S54 engine might be the most reliable and least problematic M-series engine ever produced.

Obviously, as these engines age, there is going to be a fair share of maintenance and replacement associated — but the majority of this will simply be common wear and tear maintenance. With respect to big problems, or fatal design flaws, the S54 engine has very few.

The S54 rod bearings are the only fatal design flaw, but this only affected models, and BMW eventually recalled them.

So, most of the affected vehicles have likely already had this issue taken care of. The S54 is the last naturally aspirated, I6 M3 engine.

Unfortunately, the naturally aspirated nature makes significant horsepower gains rather expensive. However, with basic bolt-on modifications you can increase the wheel horsepower from approx. Going above that, you will need to add a supercharger and, depending on the kit, can get up towards whp.

Getting to whp on a NA motor will require upgraded internals, cams, full-bolt ons, custom tunes, etc. It will be very expensive, so the more common route is adding a supercharger kit to the S The easier route: going forced induction.

Search the site Privacy Policy.The stout inline-6 S54 managed an impressive Notably, it is the last naturally aspirated inline-6 M3 engine. To be honest, this post is tough to write. As we said, the S54 engine is tough to write about common issues. Just keep in mind — the S54 is an aging engine prone to normal wear and tear.

Nonetheless, the 3 most common BMW S54 engine problems include:. Expect these issues to pop up, especially with the age of the S Be on the lookout for common symptoms.

However, a few typical symptoms to look out for include:. However, spark plugs and ignition coils may cause similar symptoms, too. Unfortunately, these issues are expensive and common on the S The good news? We get to write about water pumps, again. Every darn BMW has water pump issues. The BMW S54 engine is no exception. Expect to replace the S54 water pump everymiles.

Though, failures are not uncommon as early as 60, miles. Fortunately, this is a relatively inexpensive repair, especially if you DIY. It will likely be pretty obvious when your S54 water pump fails. They may fail gradually, but more commonly it happens quickly without any serious symptoms prior to the failure. Once the water pump fails, expect some of the following symptoms:. Coolant may begin leaking from the water pump area. The car will overheat quickly without proper coolant flow.

Once too hot, the S54 will go into limp mode. In an attempt to help cool the S54, the cooling fan will typically run at full blast. However, we recommend replacing the S54 thermostat at the same time as the water pump.

Still, not too bad.Neither the motor for North America not for Europe used in this model. Now in E46 M3 install only S Cast-iron cylinder block of this engine has been improved: increased bore to 87 mm, forged crankshaft with a stroke of 91 mm and with 12 counterweights.

The pistons are cooled by oil spray nozzles. Valves as on S50B Valve clearances are following cold engine : inlet 0. Individual throttle bodies still used on intake. The firing order on BMW S All these changes helped to increase the power of the engine to horsepower at 7, rpm and a torque at 4, rpm. Because of them S54 lost 10 HP. Differences between S54 M3 and S54 Z3M consist in the changed intake manifold and air filter housing. The maximum revs decreased to 7, rpm.

Two additional catalytic converters cased difference in 10 horsepower between US and Euro versions.

This car produced in in limited edition. It increase the power of 3. Such engine called S54B32HP. Nevertheless, S54 continued to install on Z4M till But if at your M3 is high oil consumption, then a problem in valve stem seals. If the consumption is too large, then you need to buy new piston rings. Periodically there is an overheat on S Main reasons: air in the cooling system, a dirty radiator, a water pump, the thermostat and radiator cap.

Check these details. But as these cars bought for active driving, for today practically all of them are in awful state. Aftermiles of mileagekm you need to change connecting rod bearings, timing chain and timing chain tensioner on your M3. S54 has the highest ratio of horsepower per liter among all naturally aspirated of 6-cylinder BMW engines. Nevertheless, you can get even more power if you spend a little money. This will allow your S54 easily to show more than horsepower.

After installation of these cams, to 3, rpm the motor will lose power a little, but after 5, rpm it will be increase. With such mode your E46 M3 will show about horsepower at 8, rpm. To buy stroker kit for S54 is not a good idea without it you will get good power. Instead of difficult manipulations you can just buy an ESS supercharger kit or VF and get a lot of power.

These sets are quite reliable and install on S54 stock internals.

Honda R18A.The BMW M54 is a naturally aspirated straight-6 petrol engine produced from to It was released in the E53 X5 [1] and is the replacement for the M52 engine. From tothe M54 was included on the Ward's 10 Best Engines list.

Compared with the final versions of its M52 predecessor called the 'M52TU'the M54 has a non-return fuel system, a fully electronic throttle without mechanical backup[1] [2] Siemens MS 43 engine management[3] a revised intake manifold [4] and the North American engines no longer use an iron block.

The displacement of the largest variant increased from 2. As per the M52TU, the M54 uses an aluminium block and aluminium cylinder head with cast iron cylinder liners. Variable valve timing is fitted to both camshafts [5] called " double-VANOS "a dual length intake manifold called "DISA" is used and the thermostat is electronically controlled.

There was no "technical update" TU version of the M54 produced, therefore the engine specifications remained the same throughout its 7-year production run. The S54 was marketed as the high performance equivalent to the M54, however it is actually more an evolution of the BMW S50 and shares few parts with the M Compared with the S50, the S54 features: [11] [13] [14].

This engine is designated S54B32HP and the changes include a revised intake made from carbon fiberrevised camshafts, a MAP sensor instead of the MAF sensor used in the regular S54[3] a lightweight exhaust manifold with a straighter air path which later became standard on the regular S54 and a straightened intake manifold.

They do make a business of outing folk.

I can tell you I usually ignore all reciprocal link exchange requests via unsolicited emails and recommend you do to. The quantity, quality, and relevance of links count towards your rating.

The sites that link to you can provide context about the subject matter of your site, and can indicate its quality and popularity. However, some Webmasters engage in link exchange schemes and build partner pages exclusively for the sake of cross-linking, disregarding the quality of the links, the sources, and the long-term impact it will have on their sites. IF YOU TAKE A SECOND AND VISUALISE in your head the link scheme in place and the relationship between pages via links in the reciprocal links hub scenario, you can see how easy it is to do so.

Google can probably compute and identify that one a lot faster than you can its so obvious. A useful links page out to unrelated sites on a low-quality domain is just spam to Google and more often or not the pages your links are on will just be ignored by Google, so there is no point getting a link from these pages. Linking is the foundation of the web.

Without links, there would be no web as we know it, no Google even, so never be scared of linking to useful sites or pages. In fact, Google WANTS or, at least, EXPECTS you to do this and will thank you for it at some level. Do you really want that. Of course, you should ALWAYS be LOOKING for high-quality links, whether you link back to those sites or not.

One-way links are better for ranking in search engines as they indicate editorially approved links from other sites to yours. I am working with a client at the moment in a global market that makes something amazing a lot of blue chip companies pay a lot of money for. The aim is to get the BRAND websites to VOTE for our site FIRST, so OUR search engine rankings improve, because Google now TRUSTS our site because of these new quality links on sites it already trusts.

I think all Brand managers would like another good-news-page in the SERPs, so creating a case study for their brand, on your website, is probably better than a link on a links page Google will probably eventually ignore. If a very trusted site links to my site and gave me a ranking boost, am I expected to believe that linking back to them will remove my ranking boost.

Linking back to a site that links to you is a very common thing on the web. Consider the small site that links to its industry body, and a year down the line the small site is a big player, with links from the industry body. Is that link useless. I would think Google is a lot smarter than that, at some level. I think Google would, at all times, take into account the trust and authority of the sites in question, and whether or not it has any reason not to trust the sites.

I never link to a site JUST BECAUSE THEY LINK TO ME, because the chances are, they are linking to ANY site out there regardless or not if it is a bad neighbourhood. Google reserves the right to penalise you badly if you link to one of these, or are linked from one of them. Of course, you could robots.

Anchor Text Anchor text is simply the text in the link. I would encourage it, rather than overtly advertise it. Remember, too, that what Google can easily identify in your link profile, it can penalise, filter or demote your for.If ommitted, both damped and non-damped trends will be tried and the best models returned.

If it is omitted, then the missing values are filled via spline interpolation before fitting. Example: "median" description optional A description of the time series up to 8192 characters long. Example: "This is a description of my new time series" error optional Any of the following values to specify types of ETS models: 1 (additive), 2 (multiplicative).

Multiplicative error models are only available when the objective field has strictly positive values (greater than 0). Example: 100 name optional The name you want to give to the new time series. Example: 2 tags optional A list of strings that help classify and index your time series.

This will be 201 upon successful creation of the time series and 200 afterwards. Make sure that you check the code that comes with the status attribute to make sure that the time series creation has been completed without errors.

This is the date and time in which the time series was created with microsecond precision. True when the time series has been built in development mode. See the Forecast Result Object definition below. In a future version, you will be able to share time series with other co-workers or, if desired, make them publicly available.

This is the date and time in which the time series was updated with microsecond precision. A map with keys (objective field identifiers) and with values (dataset identifiers). Those datasets contain a timestamp column, a copy the original data of the objective field, and one column per model with the values that that particular submodel computes for the objective time series.

ETS error type parameter: 1 (additive), 2 (multiplicative) The results of the ETS fits. A dictionary with an entry per field in your data. Each entry is a list of maps. Integerinterval: The interval between each forecast value. ETS trend type parameter: 0 (none), 1 (additive), 2 (multiplicative) The Akaike Information Criterion score.

The final fitted state for the ETS model with the following entries: b - Trend state. Floatl - Level state. Float s - Seasonal state. Only for ets models with seasonality. Only included for ets models where seasonality is not none. The initial fitted state for the ETS model with the following entries: b - Trend state. An abbreviated name which uniquely specifies the ETS model type, using the classification system from Hyndman.

For example, the value "M,Ad,N" specifies the ETS model type with multiplicative error, additive damped trend, and no seasonality.
