HKS 93-98 Toyota Supra Turbo 1.2mm Stopper Headgasket
The HKS 1.2mm Stopper Headgasket fits 1993-1998 Toyota Supra Turbo models equipped with the 2JZ-GTE engine. This multi-layer steel gasket uses a solid stopper frame to seal combustion chambers under high boost pressures. It supports engine builds aiming for consistent performance and reliability.
Key Features
- Solid Stopper Design: Stainless steel stoppers maintain combustion chamber volume and resist head lift in boosted applications
- 1.2mm Thickness: Provides OEM-like compression while handling elevated cylinder pressures up to 2000hp builds
- MLS Construction: Three-layer stainless steel with aramid fiber core offers heat resistance over 1000 degrees C
- Precision Bore: 86mm cylinder bore and 94mm combustion chamber diameter match 2JZ-GTE block exactly
- High Pressure Sealing: Integrated bead design ensures zero blow-by even at 40+ psi boost levels
Product Notes
- Pair with ARP 219-4306 head studs for best results in high boost setups
- Verify head and block deck surfaces are flat within 0.002 inches before install
- Handle carefully to avoid creasing thin steel layers
Installation Notes
- Professional installation recommended.
- Machine surfaces flat and clean thoroughly removing all oil residue
- Compatible with OEM head bolts or aftermarket studs torque to 90 ft-lbs in sequence
