Multi-Layer Steel gaskets are comprised of multiple embossed layers of both proprietary high-temperature coated and uncoated stainless steel, requiring less clamp load, creating less bore distortion, and conforms load distribution across the sealing area. The embossed outer layers of our head gaskets meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The MLS Gasket (Multi-Layer Steel) features an active combustion seal on multiple layers. The stainless steel outer layers utilize FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing.

The JE Pistons BMW S50B32 Euro Kit is designed for performance enhancements of the BMW S50B32 engine, which was used in the Euro-spec E36 M3. Here are the details for the specific kit you're asking about: Bore Size: 87.0mm This refers to the diameter of each piston, slightly larger than the stock bore (which is typically 86.4mm). The increase in bore size slightly raises displacement and allows for better airflow and combustion, improving power potential. Dome Volume: -10.10cc The negative dome volume indicates that the piston has a dish shape, rather than a positive dome. This affects the engine's compression ratio and helps with fine-tuning cylinder pressures. A dished piston like this allows for higher performance at high RPM, while maintaining stability. Compression Ratio: 11.50:1 This high compression ratio is ideal for naturally aspirated performance applications, offering more power output by increasing the efficiency of the combustion process. A higher compression ratio helps the engine generate more horsepower and torque from the same displacement. Material: Forged aluminum JE Pistons are known for their high-quality forged aluminum construction. This offers better strength and durability under high stress and heat, making them suitable for high-performance and racing applications. Application: BMW S50B32 (Euro-Spec E36 M3) This kit is specific to the Euro version of the S50 engine, which differs slightly from the US-spec version in terms of displacement, power output, and other engine characteristics.

Carrillo rods are your number one option for performance connecting rods! If you are looking to upgrade your M52TU / M50 engine to handle greater power, we highly recommend these Pro-H connecting rods. Upgrading connecting rods in your engine can bring several benefits, particularly if you're looking to enhance performance, reliability, and overall durability. Here are some reasons why you might consider investing in upgraded connecting rods: Increased Strength: Upgraded connecting rods are often made from stronger materials, such as forged steel or titanium, compared to stock rods. This increased strength helps withstand higher levels of stress and load, making them suitable for high-performance applications. Improved Durability: Enhanced materials and manufacturing processes contribute to improved durability, reducing the risk of connecting rod failure, especially in high-stress situations. This is crucial for engines that undergo frequent high-speed or high-stress conditions, such as in racing or heavy-duty applications. Higher RPM Capability: Upgraded connecting rods are designed to handle higher engine RPM (revolutions per minute) without succumbing to fatigue or deformation. This is beneficial for those seeking increased horsepower and torque at higher engine speeds. Reduced Weight: Some upgraded connecting rods are engineered to be lighter while maintaining strength, contributing to a lower overall rotating mass in the engine. This can result in quicker revving, improved throttle response, and better overall performance. Enhanced Precision: Upgraded rods often undergo more precise machining processes, ensuring tight tolerances and improved balance. This precision can lead to better engine stability and reduced vibration, ultimately extending the life of engine components. Compatibility with High-Performance Builds: If you're planning on modifying your engine for increased horsepower through methods like turbocharging or supercharging, upgraded connecting rods become essential. They provide the necessary strength and reliability to handle the increased stresses associated with forced induction. Prevention of Catastrophic Failures: Upgrading connecting rods can act as a preventive measure against catastrophic engine failures. The improved strength and durability reduce the risk of a connecting rod breaking, which could lead to severe engine damage. Specifications: CC(in): 5.512 CC(mm): 140 Style: PRO-H Bolt Size: 3/8 Bolt Type: WMC Pin Width(in): 0.862 Pin Width(mm): 21.89 Big Width(in): 0.862 Bid Width(mm): 21.89 Big Bore(in): 1.8898 Big Bore(mm): 48.001 Pin Size: 22mm QTY: Set of 6 Founded by Fred Carrillo in 1963, Carrillo Connecting Rods was established with an unwavering commitment to uncompromising standards in manufacturing. Fred recognized that the relentless pursuit of speed demanded an equally fervent dedication to the quality of components. This foundational philosophy remains as strong today as it was at the inception of Carrillo in 1963. At CP-Carrillo, quality and pride are inseparable. The process of crafting a CP-Carrillo rod transcends mere forging, production targets, and shipping deadlines. The evolution of connecting rod design has become a collaborative effort involving skilled specialists. Each connecting rod is a precision symphony, with material specialists, forging experts, production craftsmen, design engineers, and engine specialists contributing their expertise and artistry. Customer feedback plays a pivotal role in our continuous product improvement. The close interaction between customers, engineering, and manufacturing fosters the most effective rod designs, enhancing accuracy and service—a value that becomes apparent during your engine build. CP-Carrillo's dimensional integrity stands unparalleled, setting a standard of excellence in the industry.
