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!

Unlock the full potential of your S54’s valvetrain with our High Performance Cam Followers/Rocker Arms, built for precision, durability, and reliability in high-revving performance engines.

Crafted from forged chromoly steel and finished with a diamond-like carbon coating, these cam followers are engineered to deliver exceptional strength, reduced friction, and outstanding wear resistance, ideal for demanding street or track use. Each unit is precision-ground for consistent clearances and smooth, stable valvetrain motion at all RPMs. Despite heavy-duty construction, our design retains the same weight as the factory rocker arm, preserving OE valvetrain geometry and balance while offering superior longevity and performance.

Rocker arms wear in conjunction with the camshafts, meaning the two must be replaced simultaneously. Aftermarket and performance camshaft options (Schrick, CAT-Cams, etc.) are typically ground from softer blanks and, as a result, cannot be used with factory rocker arms. We tested our performance cam followers with aftermarket camshafts to validate compatibility, ensuring smooth, reliable, and safe operation under demanding conditions.

Features:

Forged chromoly construction for maximum strength and durability Diamond-like carbon-coated surface reduces friction, extends service life, and permits compatibility with aftermarket and performance camshaft options Precision-ground tolerances ensure consistent and quiet operation OEM weight match maintains valvetrain balance and reliability Superior wear resistance for performance and endurance applications NOTE: Rocker arms are wear items and must be replaced alongside a new set of camshafts, regardless of profile or manufacturer. Installing a new set of rocker arms onto a used set of camshafts is NOT recommended.

Kit Contents:

24 DLC-Coated Rocker Arms (required to complete both camshafts) Product Development: Our Turner Performance Rocker Arms are the result of advanced engineering, testing, and quality assurance by Turner’s Research & Development team. Every stage of development employs FARO laser scanning, SolidWorks 3D CAD modeling, and in-house rapid prototyping for precise fitment and design validation. Performance and durability are proven through Mustang AWD 500 SE dyno testing and Superflow SF-750 Flowbench analysis, ensuring each component meets Turner’s uncompromising standards for performance and quality.

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!

What's better than using standard connecting rod bearings in your next engine build? Using our Turner Motorsport WPC-treated bearings! Our process begins with King Engine Bearings bearing shells. Designed with performance and load capacity in mind, King's SV Series bearings feature a Lead-free, tri-metal Silver-based overlay with a Babbitt plating made to provide seizure resistance. Ideal for extreme-load engines, it serves as an OE replacement and can be employed as a sputter replacement. Despite offering great wear and friction resistance, the engineers at Turner Motorsport saw an opportunity to further improve King's bearing design with WPC surface treatment. WPC reduces friction and adds strength, vastly enhancing the durability of critical internal engine components. Ultra-fine particles are fired at the surface at very high speeds—similar to shot-peening, but on a much smaller scale. The treated parts come out smoother and stronger due to thermal discharge. The two greatest enemies of any high-performance engine are heat and friction, and WPC technology effectively reduces both.

One of our most popular items! We have been selling our S14 stroker kit since 1993. Since then we have sold HUNDREDS of this exact kit, and have received incredible feedback from our customers. RELIABLE Horsepower is our goal. Our E30 M3 2.5L Stroker kit uses factory BMW Evolution III parts to convert the stock 2.3 liter engine into the Evolution III 2.5 liter engine. Increasing the displacement and raising the compression yields much more torque: +50 ft/lbs @ 4000 rpm. With a stock head our 2.5 kit will make over 225 hp.

Our kit includes everything you need to convert your 2.3L into a 2.5L. We highly recommend upgrading the intake and exhaust system to allow larger 2.5L engine to breath. Call for more details and for "custom" packages. We can set you up with any other engine components you may want to replace (tensioner rails, chain guides, oil pump, etc) at the same time. For your benefit, we carry all these items (and at a great price).

The Turner 2.5 liter S14 Stroker Kit includes:

  • Genuine BMW 2.5L crankshaft w/ bearings, nut and spacer
  • 2.5L head gasket
  • Bottom end gasket set
  • Turner/Conforti Custom 2.5 Liter Computer Chip **Only available from us! This is what sets our kit apart from the "other guys kit"
  • Wiseco 2.5 forged piston set w/ rings (11.25:1 compression)
  • Genuine BMW rod bolts and head bolts (we suggest Genuine fasteners for reliability)
