BMW Engine Parts for BMW Z Series E85/6 (2003-2008)

Upgrade your engine build with Turner's WPC-treated Race Series Bearings, engineered for serious performance enthusiasts. Starting with ACL’s high-performance bearing shells, these Race Series bearings are built to withstand extreme RPMs and stress. Utilizing a "Duraglide" tri-metal construction and a high-strength overlay plate, these bearings offer superior oiling and heat resistance for high-RPM operation.

Our WPC-treated bearings take ACL’s already impressive design and enhance it even further. The WPC treatment process strengthens and smooths the bearing surface by firing high-speed, ultra-fine particles at the bearing shells, reducing friction and improving durability. This advanced surface treatment ensures smoother operation and improved heat dissipation, which are critical for any high-performance engine.

Key Features:

Duraglide Tri-Metal Construction: ACL's Race Series bearings feature a high-strength overlay for enhanced performance. Optimized Oiling: Designed to promote better oil flow during high-RPM conditions. Precise Fitment: Manufactured with OEM-level precision using micron tolerance machining. WPC-Treated for Strength: Surface treatment adds strength and reduces friction for improved engine performance. No Flash Plating: Allows for better heat transfer and bearing retention. Thermal Discharge Process: Smoother, stronger components through WPC’s unique thermal discharge technology. Enhanced Heat and Friction Resistance: Built to combat the biggest enemies of high-performance engines. Don’t settle for standard bearings—choose Turner Motorsport WPC-treated Race Series Bearings for the ultimate engine performance upgrade. Perfect for your next engine rebuild or rod bearing service!

Take the guesswork out of S54 ownership. This all-inclusive kit targets the two most notorious failure points on the BMW S54 engine: broken exhaust hub tabs and degraded internal seals.

Turner Motorsport S54 VANOS Exhaust Hub Upgrade

The factory S54 exhaust hub is a ticking time bomb. Excessive play between the drive tabs and the oil pump disk creates a rhythmic rattling that eventually shears the tabs off, risking catastrophic engine failure.

While other kits require deep-engine surgery, our Turner Motorsport Hub Upgrade offers a "work smarter" approach.

Precision Engineering: Developed using 3D scanning and CAD modeling for a perfect, interference-free fit.

Superior Materials: Machined from high-strength 4340 steel and hardened to OEM specifications.

No Re-Timing Required: This bolt-on fix eliminates the failure point without the need to disassemble the VANOS unit or disturb engine timing, saving hours of labor.

ECS Tuning VANOS Seal Kit

The original BMW seals are made of Buna-N rubber, which quickly hardens and loses its sealing properties when exposed to synthetic oil and high heat. Our ECS engineering team has corrected this flaw.

Viton™ Upgrade: We utilize high-performance Viton O-rings for the internal seals, seal plate, and solenoid.

Chemical Resistance: These seals are designed to remain pliable and effective for the life of the engine, restoring lost low-end torque and smoothness.

ECS Tuning Rattle Repair Kit

Eliminate the dreaded "marbles in a can" sound. This kit addresses the axial play in the VANOS helical gears.

Hardened Steel: Our rings and washers are precision-ground to resist the wear and deformation that lead to engine rattle.

Silent Operation: Restores the refined sound and feel of your S54 across the entire RPM range.

Schrick has been dedicated to engine performance through the development of only the highest quality camshafts for more than 40 years. They've created a bond with BMW enthusiasts nearly the entire time, offering options for both the street and track using top materials for strength and accuracy. Schrick has grown into a technology center offering one of the most advanced locations for engine testing and manufacturing.

These cams are a direct replacement for the stock cams and give a solid 15+ horsepower boost at the top end and great midrange torque increases too! More gains can be expected with intake and header upgrades and custom software tuning. A slightly lumpy idle is expected at cold start, but will be smooth once at operating temperature.

These Schrick cams were initially developed for the M3 CSL, but they also work well on the US and other non-CSL S54 engines. With more duration, they are a great match to high-flow headers and CSL intake plenum upgrades.

KIT INCLUDES

Schrick 280-Degree Exhaust Camshaft Schrick 288-Degree Intake Camshaft 24 Turner Motorsport DLC-Coated Performance Rocker Arms NOTE: Camshaft replacement requires multiple special tools. We offer the Genuine BMW Camshaft Press (T#171829) and a Schwaben Camshaft Alignment Tool Set (T#395239) to aid in installation.
