When upgrading your turbos or increasing your BMW's power potential, it's important not to overlook your fuel pump. Both low and high-pressure fuel pumps can only flow so much fuel, limiting power potential regardless of turbo size or other power adders, especially when running an ethanol blend. Upgrade your BMW fuel pump with Precision Raceworks' Low-Pressure Bucketed Fuel Pump Kits. Precision's low-pressure fuel pumps are designed to flow significantly more fuel than your BMW's stock system, ideal for customers who are upgrading their vehicles or plan to run blended fuel or E85 alone! This is a true plug-and-play solution that anyone can install in their home garage and start taking advantage of the benefits right away. Precision Raceworks' Stage 2 bucketed fuel pump kit includes a genuine Walbro 450 (F90000274) fuel pump, capable of supporting up to 575whp on 93 octane pump gas or 500whp on 100% E85! In order to prevent having to send in your fuel pump, each of Precision Raceworks' kits includes thorough instructions and all of the items required to assemble your kit at home. This prevents delays in shipping, potential damage to your stock fuel pump housing, and reduces assembly costs to keep prices low. It also improves installation as there is no guesswork on engagement and sealing of o-ring or complications and risks of tightening clamps that can poke holes in critical plastic components nearby. While all bucketless fuel pumps flow .2gpm more than a bucket design that retains the venturi, it comes at a cost. Bucketless pumps should not be driven on tanks lower than 1/4 full and should not be used for road course racing. This is not a disadvantage of only bucketless designs, but also a disadvantage for any bucket design which deletes the venturi. If you do not plan on road course or drag racing (not street racing) and are responsible at maintaining 1/4 tank of fuel during spirited driving, bucketless pumps can be a cheaper alternative for you.

The roller rocker arms transfer the rotational force of the camshaft to open the intake and exhaust valves. One end is raised and lowered by the rotating lobe of the camshaft, while the other end acts on the associated valve stem. If a roller rocker arm has failed you may experience a constant ticking noise during engine operation, or alternatively if the rocker arm has broken, you will receive multiple misfires and a rough running engine.

If you're noticing misfires, poor fuel economy, reduced engine performance, or ignition-related diagnostic trouble codes (DTCs), a failing ignition coil is likely the cause. Late-model BMWs, such as the E60 M5, E63 M6, and E64 M6, use a coil-on-plug ignition system, where each cylinder has its own coil and spark plug for efficient ignition. When a coil fails, the affected cylinder won't receive a spark and will misfire. Even if the misfire doesn’t trigger a DTC, you’ll still feel the difference in engine performance—rough idling, hesitation during acceleration, or a strong fuel smell. To avoid these issues, we recommend replacing your ignition coils every 40,000-60,000 miles.

The S85 engine uses a specialized ignition system called Ionic Current Control, which differs from traditional knock sensors. BMW engineers developed this system to more accurately detect pre-ignition and misfires in the high-revving, ten-cylinder S85. Instead of relying on conventional knock sensors, the system uses each spark plug to measure current after the power stroke, transmitting that data to the Ionic Current Control Unit (ICC). This allows for precise monitoring of combustion events. To support this, the S85’s ignition coils are specially designed with a modified “pencil” shape and lack a Zener diode in the secondary winding, allowing for accurate current measurements without triggering fault codes in the engine control unit (DME). These ignition coils are manufactured to the exact specifications of the OE Ionic Current Control-compatible ignition coil, and will not trigger ignition-related fault codes in the DME.

Bavarian Autosport ignition coils are engineered for reliability, delivering a consistent, long-lasting spark. These high-quality OE replacement coils are specifically designed for your S85-powered E60 M5, E63 M6, or E64 M6. Constructed with durable, heat-resistant plastic and featuring premium rubber spark plug boots, each boot is pre-lubricated with dielectric grease to ensure smooth installation and prevent corrosion.

Whether you're fixing misfires, replacing a faulty coil, or performing preventative maintenance on your S85 ignition system, trust Bavarian Autosport ignition coils for a dependable, lasting repair.

FEATURES:

Durable, heat-resistant plastic: Built to withstand extreme temperatures and harsh driving conditions for long-lasting durability. Pre-lubricated, high-quality rubber boots: Prevent moisture and corrosion while ensuring smooth, easy installation. OE-quality construction: Meets or exceeds original equipment standards for perfect fit, reliable performance, and effortless installation.

Designed and manufactured by Clevite to BE Bearing specifications.

These bearings replace the factory BMW rod bearings. The original BMW bearings have too little clearance, which leads to premature bearing wear and can cause early engine failure.  Furthermore, the factory BMW bearings are made from tin-aluminum which are 5-times harder than a softer lead-copper bearing design. A softer bearing is better for your engine and more tolerant of foreign particles suspended in your oil.

These BE Bearings feature a state-of-the-art Clevite Tri-Metal design with the Clevite Tri-Armor(tm) coating.

  • Lead-copper design for greater durability and easy tracking with oil analysis like Blackstone (recommended).
  • Designed with extra clearance to "fix" the BMW rod bearing design flaw.
  • Designed for use with factory 10W60 weight oils.
  • Tri-Armor coated for low conditions during cold start
  • Ideal for start-stop vehicles
  • Applicable for BMW engines S85B50
  • Standard Clearance
  • Sold as complete set (10-cylinders)

Fits the following BMWs:
2005-2010 E60 BMW M5
2005-2010 E63/64 BMW M6

Under certain conditions, the N55 crank hub likes to spin, without warning and even when the engine is in perfect health. The engineers at Vargas saw and dealt with this problem time and again, and they saw fit to do something about it. This hub uses a proprietary "Spline Lock" technology that uses high tolerance machined splines which press into the crank, and positively lock the hub to the crank. The splines are machined in such a way that rotational forces drive the hub, and splines deeper into the crank meaning when the hub encounters a situation that would normally slip a stock hub the splined hub is driven into the crank to keep it in place (much like a splined extractor). Features: Installs the same as a stock hub Does NOT require the crank to be drilled for pins Manufactured from Harndered 17-4SS We suggest the Crank Hub System ONLY be installed by a qualified shop or technician. Timing tools are 100% REQUIRED if installed improperly engine damage may occur. DISCLAIMER: VTT and ECS are not responsible for any engine damage caused by improper installation, or misuse of the crank hub solution.

The N54 suffers from a weak point in its crankshaft. It has been reported that when increasing the power to the engine, the crank hub can move or spin slightly under an extreme load. This is most apparent under high-rev downshifts or in the case of increased boost pressure which creates more stress on the engines rotating assembly. In order to keep this from happening, the crank bolt must be secured to the hub to keep it from backing off, but this can be a tricky solution since a simple dab of Loctite will not suffice. 

Here is an easy, and cost-effective way to secure the situation; The VTT N54 crank bolt capture. This lightweight and durable ring slips over the head of the crank bolt fully encapsulating it, and locks it to the crank hub and eliminating its ability to spin. The VTT-CBC is 100% Billet Aircraft Grade Aluminum, Anodized black to protect it from the elements, and give it a stealth look. What's more is that it weighs only 1.3 Oz's meaning you aren't adding excess mass to the crankshaft which will avoid any imbalance or vibration issues.

While this is not a full fix for all crank hub spinning issues, the engineers at Vargas have found most issues have stemmed from the bolt itself backing out, and this is a great way to keep that from happening. Extremely lightweight at only 1.3 Oz's it adds virtually no weight to the crank which is important for balance and vibration.

Kit Includes:

  • 1x Aluminum Crank Bolt Capture
  • 8x Fasteners Gr. 12.9

This part fits the following BMWs:
2006-2013 N54

It is a well-known issue on the BMW N54/55 platforms that your serpentine belt can fail for various reasons. When this happens, there is a high chance of the belt getting sucked behind the front damper pulley and then being pushed past the crank seal into your oil pan. From there it can get sucked into the oil pick up causing total engine failure. Even if you do not lose the engine, it is a COSTLY repair to remove the sub-frame and drop the oil pan to remove the belt. The best way to combat this is to watch for oil leaks and keep up on your maintenance. BUT, even with those preventative measures, pre-mature belt failure can occur. This crank seal guard installs over your front crank seal and will keep the belt from being sucked in if a belt failure does occur. This is a cheap way to ensure you do not end up having to replace your motor from oil starvation due to an ingested belt. Vargas' seal is different from those already on market in two major ways. Firstly, it is not offensively priced. Secondly, it is 100% billet with no welds on the tabs to break, no cheap bent thin steel pieces. 100% Billet 6061-T6 aluminum, anodized black for long-term corrosion resistance. Crank Seal Guard includes: One VTT Billet N54/55 Crank Seal Guard Two extended 12.9 Grade bolts, and two stainless washers We highly recommend you install WITH a crank bolt capture at the same time, as you have to remove the damper anyway. Then you will get the benefit of helping eliminate the dreaded spun crank hub and the crank seal issue

The crankcase oil vent system on the N52/N54 is one of its weakest and cheaply designed systems. We see crankcase vent issues on even stock engines but with more boost the problems are exponential. This Vargas upgraded PCV valve, and an oil catch can, are what the N54 engine needs and may alleviate most of your oil and boost leak issues. The PCV valve is supposed to let oil either return to the oil pan or pass through the intake manifold and get burned up in the combustion chamber. However, BMW used a weak plastic vent valve that doesn't seal well when under boost. Instead of  closing and venting the oil out of the intake, it's forced through this valve and into the intake and coating your valves with oil residue and carbon. Most boost equals more oil forcing its way by. This upgraded N54 PCV valve uses higher grade materials, including aluminum, to provide a better seal and prevent oil from entering the intake. It's an easy install and a must-have item when considering any turbo work.
