Bottom End Gasket Kit - Nissan Inline-6 88-02

The Bottom End Gasket Kit for Nissan Inline-6 engines (1988–2002) is an essential rebuild component for any serious engine restoration or high-mileage overhaul project. Designed by Cometic Gaskets—the industry standard for precision sealing—this kit addresses the crankcase and lower-end sealing surfaces where combustion pressures and oil circulation demand absolute integrity. Whether you're refreshing a tired KA24E, SR20DET, or RB-series build, a quality gasket set prevents oil weeping, combustion blow-by, and coolant crossover contamination that compromise reliability and performance.

Cometic's Pro Series gaskets utilize advanced composite and elastomer materials engineered to withstand sustained boost pressure, thermal cycling, and the chemical stress of modern synthetic oils. Each gasket surface finish is CNC-machined to tolerances that ensure consistent clamp load and eliminate micro-leakage paths common in OEM gaskets. The bottom end kit includes oil pan, crankshaft seals, timing cover gaskets, and all lower-block sealing surfaces—everything needed for a complete lower-end rebuild without mixing manufacturer specifications or material compatibility issues.

This kit suits builders pushing modest boost levels, street restorers seeking long-term durability, or anyone replacing gaskets during engine-out service work. Nissan inline-six platforms—particularly turbocharged variants—benefit from Cometic's precision because bottom-end leaks directly affect catch-can systems and engine bay cleanliness. Installation pairs seamlessly with upper-end gasket kits for a complete overhaul, and compatibility spans all 1988–2002 Nissan inline-six configurations used in Z32 300ZX, S13/S14/S15 Silvia, A31/A32 Cefiro, and various truck platforms.
