Upgrade and protect your high-horsepower Nissan SR20DET engine with the legendary APEXi 814-N103 Metal Head Gasket, available now from Straight Six Imports, your trusted Canadian performance partner.

Engineered with APEXi’s extensive racing heritage, this essential upgrade replaces the weak factory gasket to prevent combustion gas leaks and catastrophic engine failure in turbocharged and high-boost applications. The SR20DET engine, commonly found in the Nissan 240SX (S13, S14) and Silvia (S15), is prone to gasket failure under extreme pressures—a risk eliminated by upgrading to a multi-layered metal gasket.

Key Features & Benefits:

• Ultimate Seal: Features a superior full grommet design and precision-cut metal layers to ensure a complete and secure seal for maximum durability.

• High-Boost Reliability: Built to withstand the extreme temperatures and pressures of high-output, turbocharged SR20DET motors.

• Optimal Specifications: This specific gasket features an 87mm Bore and a thicker 1.5mm Compression Thickness (T=1.5), which can help slightly lower compression for even higher boost applications (check your specific build requirements).

• Genuine JDM Quality: Trust in authentic APEXi performance parts to complete your engine build with uncompromised Japanese quality.

Protect your investment and unlock the full potential of your Nissan 240SX SR20DET or Silvia with the confidence that only an APEXi metal head gasket can provide. Shop the 814-N103 today and get fast shipping across Canada.
