VAC's S65 bearings are embraced by BMW engine builders world wide. Popular for both forced induction and N/A builds, their coated bearings are "friction resistant" making thermal breakdowns that can occur due to lack of lubrication a much less common occurrence. Helping to prevent premature engine failures on street cars, and spun bearings under stress at the track when things are most critical.

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.

Upgraded valves designed for high horsepower applications! Our valves are not finished from generic blanks rather they are specifically designed for each and every application. We work relentlessly, testing and researching every aspect trying to improve the air flow of our designs. With every valve design, we strive to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. It’s unlikely you will find any of our competitor’s valves with stricter dimensional tolerances than our Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere! Optimum high flow rates are achieved by ensuring that our valves are manufactured with the best angles for each application. We consider back cut, under cut and valve head angles for each application to produce the optimum high flow rates for each application. In 2006 we introduced our stem Superfinishing as a standard addition to all of our valves at no additional cost. When our Superfinish is combined with our Black Nitrided valve, it reduces the surface roughness to 1/3 of our chrome coated valve. The end result… unsurpassed performance and durability. Our intake valves are made exclusively from an enhanced versions of EV8 (21-4N) steel. Black Nitride Coating: This is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life. Please see below for more benefits of our Black Nitride valves. Black Nitride Coating Head Diam: 33mm Material: Stainless Steel 21-4N Groove Type: Triple Groove Length: 123.7mm Stem Diam: 6.95mm

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.

This pump features two important upgrades: This pump is engineered with VAC's famous Oil Pump Upgrade kit integrated in its design; this means a stronger gear drive mechanism for much lower likelihood of pump failures on the track. VAC has not only improved the physical reliability of the pump itself but also fit a custom gear with a larger sweep area to the pump mechanism, increasing volume by a welcome 22% An excellent upgrade for Road Race, Autocross, Time Attack, Drift, Hill Climb, Rally, Drag Race, Roll Race & forced induction applications. Lubrication issues are a common killer of BMW engines. The dual-pickup pump is much better than a standard single pickup, but this pump is a dramatic improvement over both.

VAC's S54 Vanos Hub is designed as a direct replacement for the fragile BMW OE Vanos Hub which typically fails due to a broken drive pin. The VAC Hub has an Upgraded Drive Pin design, which is larger in diameter, as well as more material on the outside wall of the pin. In addition, the hub is made from 4340HT Billet Bar and heat treated to the same BMW OE Rockwell Hardness spec. The upgraded design is not only significantly stronger, but the larger diameter Drive Pins also minimize the huge clearance (approximately 1mm) that was in the original design by BMW and reduces the clearance to 0.2mm. This is critical in helping greatly reduce or eliminate the VANOS noise.

Also, this upgraded design eliminates the need for modifying the Pump Ring or having to buy a replacement, which further saves you money!!!
