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.

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.

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.

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 VAC Motorsports ARP Head Stud Kit was put together by VAC and ARP’s finest engineers. This is a completely custom kit designed specifically for the almighty N54. *High Boost (25+ psi application) option features: (14) 11mm ARP Head Studs (14) ARP Washers for 11mm Studs (14) ARP Nuts for 11mm Studs Install Tips: MUST drill and tap the (4) 9mm holes in the engine block to make them 11mm holes. This way all the engine block holes are 11mm, and fit ALL (14) 11mm Studs. Torque Specs: All studs torque down through 3-equal steps to 95 ft lbs ***This is NOT the Chrysler and Volvo stud kits! VAC Motorsports and ARP engineers designed and assembled this kit with high grade material, specifically so standard street-use or high-boost N54 owners have a PROPER kit that does not fail over time, such as the retro-fit Chrysler and Volvo head stud kits. ARP is the world leader in fastener technology. Makers of the finest fasteners in the market, especially for BMW engines, ARP is the brand you can count on when you want the highest reliability possible. If you are looking for high performance from your BMW engine, then ARP Head Stud Kits are a must. All kits come complete with hardened parallel-ground washers and aerospace-quality nuts.

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.

One major hurdle for a track-only car is the limitation of the hydraulic valve lifters in the M50, S50-US, M52, S52-US, M52TU, and M54 engines. These effectively limit your revs to 7200-7300 RPM as the valves 'float' at higher revs, leading to piston-valve contact. By converting to a machined solid lifter, and upgrading other areas of the engine, you can configure the valve train to withstand high RPM running. Not only can you tune for more power, you can help prevent damage during a mild mechanical over-rev.

This kit includes the mechanical spacers to convert hydraulic lifter tappets to solid lifters. The lifter bucket remains in place with the Schrick solid tappet replacing the original. These work on all M50, M52, S50, S52 and M54 engines and were proven in normally aspirated as well as supercharged engines. A custom camshaft is required.

Professional installation and setup is mandatory as these require complete assembly of the head, checking valve lash, then dis-assembly and machining of the Schrick tappet to spec. This kit includes enough spacers for 24 valves. We also carry individual parts, if you are looking for single pieces. This price is for a full set of 24.

For the US E36 M3. Schrick 264/256 degree camshafts boost mid-high end power for that extra motivation at higher rpm. Low-end torque is not seriously affected due to the M50/M52s VAN0S System. And, higher profile cams work extremely well with an upgraded intake and exhaust. When upgrading the cams there are other areas you must take into consideration. Higher-flow fuel injectors, larger mass-air sensor, and custom programming are strongly recommended. Turner Motorsport sells complete intake & cam packages that boost power to over 290hp. See the Engine section under Camshafts for more info.
