Toyota GT86/Subaru BRZ FA20 Rod-Only Forged Build

Looking to upgrade the strength of your engine? Our Rod-Only Forged Build is designed for drivers who want extra peace of mind and durability. Whether you’re pushing the limits of naturally aspirated performance or adding forced induction, this build focuses on reinforcing the weakest point of the FA20 engine — the connecting rods — while offering customizable upgrades to suit your goals.

Starting at £4,000, this build is perfect for enthusiasts who want a stronger and more reliable engine without opting for a full bottom-end rebuild.

What’s Included in the Rod-Only Forged Build?

  • ACL Race Bearings: High-performance bearings designed to handle increased loads and reduce friction, even at high RPMs.
  • Skunk2 Alpha Conrods: Forged conrods that are significantly stronger than stock, capable of withstanding the extra power and torque from turbocharging or aggressive driving.
  • Kelford Valve Springs: Uprated valve springs prevent valve float at high RPM, ensuring smoother operation and improved high-end power.
  • ARP Head Stud Kit: High-strength head studs provide superior clamping force, reducing the risk of head gasket failure under increased cylinder pressure.
  • Cosworth Head Gaskets: Performance-grade gaskets ensure a perfect seal, offering exceptional reliability even under boosted conditions.
  • Low-Temperature Thermostat: Reduces engine operating temperatures to maintain safe conditions during spirited driving or track use.
  • Killer B Pickup Tube: Upgraded for improved oil flow, essential for high-G cornering or prolonged hard driving.
  • ARG Performance Baffle Plate: Controls oil flow to prevent starvation, particularly during aggressive driving or track days.
  • Piston Rings and Light Hone: Fresh piston rings and a light cylinder hone improve compression and ensure a refreshed, tight seal.
  • Complete Gaskets and Seals: Full engine reseal with premium components to prevent leaks and ensure long-term reliability.
  • Machining and Blueprinting: Precision machining, balancing, and blueprinting to maximize performance and durability.
  • Ultrasonic Carbon Clean: Removes carbon deposits from intake and exhaust valves, restoring power and improving efficiency.
  • All Fluids, Oil, and Filter: Fresh premium oil and filters to protect the newly forged engine from day one.

The Rod-Only Forged Build is the ideal solution for FA20 owners who want to strengthen their engine for higher performance without the expense of a full bottom-end rebuild. By reinforcing the connecting rods — the engine's known weak point — and upgrading key components, you’ll gain:

  • Increased Durability: Handle higher power levels with confidence.
