If there is one weak point to the internals of the M20 engine, it's the camshaft rocker arms. They're actually designed to be the weak link to prevent more extensive damage elsewhere in the valvetrain. The rocker arm actuates the valves as the cam lobe makes contact. But sustained running at high RPM will cause the valves to 'float' or stay open which can lead to contact between the piston and the valves. If this happens too often, it will fatigue and snap the rocker arm. Therefore, any track driven E30 should have the rockers inspected or replaced often, along with a correct valve adjustment. And any high mileage M20 engine is running the risk of failure because of fatigue and weak valve springs. It's also a good idea to use new rocker arms any time a new cam is installed as the cam and the rocker wear together.

Replacement of the rocker arms can be done with the cylinder head in the car but more often, the head is removed. This makes removing the rocker shafts easier. Either way, a new cylinder head gasket set is recommended as it includes all of the gaskets and plugs that you would need. If the head stays on the car, the radiator may need to be removed to allow more access for the shafts to come out. Replacing the engine timing belt is not done at the same time and should be treated as a separate job.

These Febi M20 rocker arms are sold per rocker (order 12 for a complete set). You may also want to replace the eccentric adjusters as it's easy to do and worn eccentrics may prevent you from properly adjusting the valves afterward.

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.

Despite the fact that BMW engineers some of the worlds most revered engines, during number crunching something always has to be a compromise. One item that is always found to be a weak point- the OEM hardware. It is definitely sub-par for real performance use under high stress such as modded engines and track use. We use these fasteners on all of VAC's in-house head builds. Whenever the head is coming off, your switching to forced induction, or if you are simply prepping to drive your car hard; we highly recommend switching to far superior race-grade hardware. These Head Stud Kits greatly improve reliability; helping to eliminate movement of the of the cylinder head and intern, gasket failure caused by inferior OEM head-bolt stretch. This is the #1 cause of premature head gasket failure, especially on boosted or high output engines. Though more expensive than OEM, converting to one of VAC's head studs kits will not only give added strength and reliability when its needed most, but provides the most accurate torque readings because studs don’t “twist” into the block; all clamping forces are on one axis, and there is less force exerted on the normally stressed threads of the block. This increases block and hardware life and typically makes the head easier to properly install to the block, a blessing if your head may have to be removed more than once. Especially in the time crunch of racing, when engines are dissembled frequently, studs make removing and installing the cylinder head on to the block a much easier task. By allowing the studs to act as a guide on to the head, your head slides on and off and also ensures proper alignment of the head and gasket for the same reason. It is similar to converting your wheel-bolts to wheel-studs.

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. Replace your eccentric shaft with this high-quality part from OEM Febi to restore performance and eliminate valve lift issues without the marked-up price of a Genuine BMW eccentric shaft.

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.
