GReddy 80mm Oval Exhaust Gasket for 1989-2002 Nissan 240SX Silvia SR20DET Subaru Impreza WRX
The GReddy 80mm Oval Exhaust Gasket provides a multi-layer steel seal for high-performance exhaust manifolds and downpipes on Nissan SR20DET 240SX and Silvia models from 1989 to 2002, plus Subaru Impreza WRX 2002-2007. This gasket withstands extreme heat over 1600°F and high pressure from turbocharged engines to stop exhaust leaks and preserve boost levels. It serves as a direct replacement for worn stock gaskets in tuned exhaust setups.
Key Features
- Multi-Layer Steel Build: Stainless steel layers flex to seal uneven flanges and resist blowouts during high exhaust flow
- 80mm Oval Design: Matches port size on GReddy turbo manifolds for SR20DET and EJ20/EJ25 turbo applications
- High-Temperature Resistance: Handles over 1600°F for consistent performance in turbo systems
- 4-Bolt Pattern: 70mm x 52mm spacing fits JDM performance flanges directly
- Thin Profile: 1.6mm thickness reduces exhaust restriction with secure compression
Product Notes
- Inspect manifold and downpipe flanges for flatness before installation
- Torque bolts to 20-25 ft-lbs in cross pattern for even clamping pressure
- Store in dry area to prevent corrosion on steel layers
Installation Notes
- Professional installation recommended.
- Clean mating surfaces with wire brush and degreaser for optimal seal
- Compatible with OEM or GReddy hardware replace studs if stretched

Gasket Kits
Engine gasket kits are essential for any major engine service, rebuild, or head replacement, providing matched sets of gaskets in a single purchase that ensures all sealing surfaces are renewed simultaneously. A proper gasket kit from a quality manufacturer includes the head gasket, intake manifold gasket, exhaust manifold gasket, valve cover gasket, front cover seal, and all accessory gaskets required for a complete engine teardown and reassembly. Using a quality gasket kit rather than individual gaskets sourced from different suppliers ensures consistent material quality across all sealing surfaces and simplifies the parts sourcing process for engine rebuilds. Whether servicing a blown head gasket, completing a bottom-end rebuild, or refreshing a high-mileage engine, a full gasket kit is the most efficient and reliable way to approach the job. Popular Upgrades Fel-Pro full gasket sets are the most popular choice for domestic engine rebuilds, covering GM LS and LT engines, Ford Mod...
