HKS 89-99 Eagle Talon TSI 4G63BT 1.2mm Stopper Head Gasket (86mm Bore/8.6 CR)

The HKS 1.2mm Stopper Head Gasket (2301-RM006) fits 1989-1999 Eagle Talon TSI models with the 4G63BT turbo engine. This gasket uses a 86mm bore design tuned for 8.6 compression ratio to handle high cylinder pressures in boosted applications. It delivers consistent sealing for reliable power gains in DSM performance setups.

Key Features

  • Stopper Ring Design: Solid stainless steel stopper surrounds the combustion chamber to resist head lift and seal extreme boost levels up to 40psi.
  • Multi-Layer Steel Build: Three-layer construction with durable stainless steel core offers reusability and long-term reliability in racing conditions.
  • 1.2mm Thickness: Compressed height maintains exact 8.6 CR on stock pistons for balanced power and detonation resistance.
  • 86mm Bore Sizing: Matches stock and light overbore 4G63 blocks for precise cylinder head alignment.
  • Nitrile Rubber Beads: Enhanced outer sealing prevents coolant and oil leaks under high heat cycles.

Product Notes

  • Confirm engine bore measures 86mm prior to installation.
  • Pair with ARP head studs for maximum clamping force.
  • Store in dry conditions to preserve rubber sealing layers.

Installation Notes

  • Professional installation recommended.
  • Machine cylinder head and block surfaces flat to 0.002 inches.
  • Torque in three stages using M12 head bolt pattern sequence.
