Toyota GT86/Subaru BRZ FA20 Rod Knock Rebuild

Hearing the dreaded rod knock? It’s one of the worst sounds for any FA20 engine owner, signaling internal damage that requires immediate attention. Unfortunately, rod knock is a common issue on the FA20 platform, often caused by oil starvation or prolonged high-RPM driving. Left untreated, this issue can lead to complete engine failure.

At ARG Performance, our Rod Knock Rebuild service goes beyond simply fixing the problem. We completely overhaul your engine, rebuilding it with upgraded components designed to enhance durability, reliability, and performance. Whether you’re planning to daily drive your car or push it on track, our rebuild ensures your engine is ready for anything.

What’s Included in the Rod Knock Rebuild?

  • ACL Race Bearings: High-performance bearings with increased load capacity, specifically designed for engines that see high RPMs and aggressive driving.
  • New Crankshaft and Rods: The damaged crankshaft is replaced with a brand-new OEM or upgraded aftermarket crankshaft. Connecting rods are inspected for heat damage and replaced as needed to ensure reliability.
  • Low-Temperature Thermostat: Reduces the engine’s operating temperature to help prevent future overheating and damage, improving long-term engine health.
  • ARG Performance Baffle Plate: A custom-designed baffle plate that controls oil flow within the engine, preventing oil starvation during hard cornering and high-speed driving.
  • Killer B Motorsport Oil Pickup Pipe: An upgraded, stronger oil pickup pipe that ensures efficient oil delivery even under extreme driving conditions.
  • Complete Gasket and Seal Kit: All engine gaskets and seals are replaced with high-quality components, ensuring a leak-free, perfect seal.
  • Premium Fluids, Oil, and Filter: We use top-quality fluids and filters to protect your freshly rebuilt engine and ensure it runs optimally from the start.
  • Ultrasonic Carbon Clean: Removes harmful carbon deposits from the intake and exhaust valves, restoring engine efficiency and improving performance.

Our Rebuild Process

1. Engine Removal and Diagnosis

The engine is carefully removed from the vehicle and stripped down to a bare block. We assess the extent of damage, focusing on the crankshaft, rods, and bearings.

2. Precision Machining

The engine block and crankshaft are measured, machined, and refinished to exact tolerances. Damaged components are replaced with high-quality alternatives.

3. Upgraded Components Installation

We install ACL race bearings, a new crankshaft, upgraded rods, and other premium components, ensuring your engine is built to handle spirited driving and track conditions.

4. Engine Assembly

The engine is reassembled with new seals, gaskets, and hardware. We meticulously torque every component to factory or performance specifications.

5. Testing and Quality Assurance

Every rebuilt engine is rigorously tested to ensure it meets our strict quality standards. From oil pressure checks to leak-down tests, we leave nothing to chance.

Other Services to Consider While the Engine is Out

With the engine removed, it’s the perfect time to carry out additional upgrades and maintenance. Taking care of these services now can save time and labor costs later. Options include:

  • Clutch and Flywheel Replacement: Upgrade to a stronger clutch and lightweight flywheel to handle increased power and improve response.
  • Oil Cooler Installation: Add a thermostatic oil cooler to regulate engine temperatures during track use and spirited driving.
  • Header and Exhaust Upgrades: Install performance headers or a full exhaust system to enhance engine flow and power output.
  • Engine Mounts: Replace worn mounts with upgraded options for better stability and reduced drivetrain movement.
  • Transmission Service: Refresh the gearbox with new fluid or consider upgrades for improved performance and durability.
  • Turbocharger Installation: If you're considering forced induction, now is the time to add a turbo kit for a massive power increase.

These additional services ensure your car is fully optimized and ready for maximum performance when the rebuilt engine is reinstalled.
