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

New rocker arms (cam followers) are required during any new camshaft installation on the S54 engine. Otherwise the original rocker arm will wear the new camshaft lobe unevenly. These are the Original BMW S54 rocker arms and used on the original E46 M3 CSL cams as well. While these are fine for CSL cam upgrades or the Schrick 280/272 cams, the Schrick DLC rocker arms are better all around, especially when used with the more aggressive 288/280 or higher cams.

Priced per rocker.

One crucial upgrade that can significantly improve your driving experience is Turner Motorsport's WPC Rod Bearing Replacement Kit, coupled with ARP Rod Bolts for increased durability.

Enhanced Durability: The WPC Performance Rod Bearing Replacement Kit is designed with superior materials and manufacturing processes. WPC treatment reinforces the surface of the bearings, making them highly resistant to wear, which is essential for high-revving engines like the S54. This durability ensures your engine will stand the test of time, even under strenuous driving conditions. Improved Performance: By reducing friction and wear, WPC-treated rod bearings allow for smoother and more efficient engine operation. This increases power and responsiveness, providing a more exhilarating driving experience. Whether tearing up the track or enjoying a spirited weekend drive, you'll notice a difference in your vehicle's performance. Precision Engineering: Crafted from premium quality materials, these bolts and bearings offer exceptional tensile strength and structural integrity. This guarantees that your connecting rods will stay securely in place, even during high-stress situations. Your engine's components will work in perfect harmony, minimizing the risk of catastrophic engine failure. Preventative Maintenance: The S54 is notorious for rod bearing failure, often necessitating complete short block replacement. Choosing to proactively replace your rod bearings with our WPC offering ensures smooth operation and eliminates potential engine failure. Included in the kit:
