BE Bearings, in conjunction with Clevite, an OE bearing manufacturer, have redesigned and manufactured the bearings for greater clearance and have changed the original material composition from tin-aluminum to lead-copper. This upgrade incorporated the state-of-the-art Clevite Tri-Metal design and featured a Tri-Armor™ coating. This allows for the additional lubrication for wear prevention, plus, the softer bearings are better for your engine and are more tolerant of foreign particles suspended in your oil. Another benefit from this is that the oil can now be sent for testing to accurately gauge the amount of wear occurring in the engine.

As the S50/s52/m50/m52 engines start to rack up the miles it is a good idea to replace the oil pump with this Genuine BMW part. We also recommend replacing the oil pump nut as it has a tendency to back off over time especially during track use. While you are in there we also recommend replacing the oil pump pickup tube with this reinforced unit from BMW, as the tubes have a tendency to crack on track cars.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

Anyone with a modified N54 knows the risks involved. Upping the performance of any engine can come with some inherent risk; if we add more boost but not fuel, detonation will occur (or worse). Furthermore, improper installation, maintenance, or operation can turn a perfectly healthy engine into a paperweight. The worst failures, however, are the ones we don't plan for. When the engine simply can't handle the stresses its put under, or the design is such that it simply does not support extreme conditions. Enter the N54 crank hub. Under certain conditions, it likes to spin without warning, 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 that 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). Vargas spent many months testing, and retesting this design, utilizing well over 10 different samples to come to the final production version. During testing, the final hub managed to break the testing rig before slipping. These have been bench-tested, and real-world tested on the VTT N54 race car spinning 8K RPM, and making well over 900WHP. 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 Turner Motorsport are not responsible for any engine damage caused by improper installation, or misuse of the crank hub solution.

What's better than using new crank bearings in your next engine build? WPC-treated bearings! What is WPC, you ask? WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. What are you waiting for? Use WPC-treated bearings on your next engine build or crank service!

Both the N55 and S55 engines are plagued by the same issue when chasing high horsepower numbers... the dreaded crankhub failure. Fortunately MMR Performance has released an upgraded version of their already stout single-piece crankhub, but this time offering a 4-pin dowelled location that locks onto the front of the crankshaft. This configuration eliminates the multi-piece crankhub with friction discs in favor of a more robust single piece crankhub. Recommended for high-powered cars over 700 Horsepower

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 eccentric shaft is an important component of BMW's Valvetronic system, a form of variable valve lift control. If the teeth on the gear or the lobes have worn out, this can result in improper valve lift, decreased or abnormal performance, and even damage to cylinder head components.

This kit includes the basic components needed to replace S62 rod bearings, OE connecting rod bolts and WPC-treated rod bearings. WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. Kit includes: Upper and lower WPC-treated rod bearings for extra protection against wear Connecting rod bolts

Achilles Motorsports uses an extremely hi-tech Dry Film Lubricating process that will keep friction to a minimum allowing your engine to rev faster without worry while keeping oil temperature lower. Perfect for high-performance street, sprint, or endurance racing engines, this specialized coating protects vital engine bearings on dry engine starts and during extreme temperatures and high RPM operation. This specialized coating is the same process that is the choice of professional engine builders around the world, used on all NASCAR, ALMS, and Grand-Am engines. Achilles' bearings provide increased insurance against mechanical thermal breakdown compared to the OEM type bearing, showing much less wear during routine inspections. Note For high-performance and racing engines, we strongly recommend upgrading the OEM type connecting rod bolts to an ARP Connecting Rod Bolt Set to keep your bearing and caps tight even under the most extreme conditions, eliminating potential walk and bearing problems. As with all racing and performance bearings, professional installation is required. Please check all clearances as per the manufactures specifications.

ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Each stud is heat-treated, ensuring complete heat penetration, to increase the clamping load up to 200,000 psi. ARP studs are threaded after heat-treat, which gives them 1000% (that's ten times!) better fatigue strength than studs threaded prior to heat-treat. Threading the studs after heat-treating is more difficult and costly (as it's harder on tooling) but the results are well worth the effort. These simply are the best head studs we've found and we highly recommend them in both racing and forced induction applications. Due to the additional clamping force between the head and block, these are IDEAL for turbocharged engines.
