HKS 87-92 Supra MK3 2.0mm Stopper Headgasket
The HKS 2.0mm Stopper Headgasket (2301-RT032) is engineered for 1987-1992 Toyota Supra MK3 models with 7M-GTE 3.0L turbo engines. This multi-layer steel gasket features a stopper bead design that withstands extreme cylinder pressures from high-boost applications. It delivers consistent sealing to support reliable power gains in tuned Supra builds.
Key Features
- Stopper Bead Construction: Thickened stopper area resists compression set and maintains combustion chamber volume under pressures exceeding 200 psi for boosted 7M engines.
- Multi-Layer Stainless Steel: Four-layer design with elastomeric coatings ensures gas-tight seal and durability against heat cycles up to 1000°C.
- 2.0mm Thickness: Precise quench height optimizes compression ratios for 7M-GTE turbo setups aiming for 400-600+ whp.
- High-Boost Compatibility: Proven in drag racing and time attack Supras handling 30+ psi boost without blowout.
- Direct OEM Bore Fit: Matches 7M cylinder bore of 83mm with exact port alignment for leak-free installation.
Product Notes
- Pair with ARP 7M head studs for maximum clamping force in high-boost applications.
- Inspect and resurface cylinder head and block surfaces to 0.002 inch flatness before install.
- Handle with clean gloves to avoid oil contamination on sealing surfaces.
Installation Notes
- Professional installation recommended.
- Torque in four stages to ARP specs (90-100 ft-lbs final) using moly lubricant.
- Compatible with HKS metal head gasket sealant. OEM bolts insufficient for performance use.
