Tomei Oversized Oil Pan – Nissan SR20DET | 600cc Increased Capacity | Internal Swing Baffle

Protect your SR20DET from oil starvation during high-G cornering, drifting, and circuit racing with the Tomei Oversized Oil Pan. Featuring 600cc (0.6L) of increased oil capacity over the factory pan and internal swing baffle plates, this race-proven oil pan ensures consistent oil circulation and pressure during the sustained lateral G-forces of drift and track use — without sacrificing factory ground clearance. Developed and proven on Tomei's own N2 series Silvia race car. Made in Japan.

Key Features

• 600cc Increased Oil Capacity: 600cc (0.6L) more oil than the factory pan — ensures the oil pickup stays submerged during high-G cornering and sustained drift angles, preventing oil starvation that can cause bearing damage and catastrophic engine failure
• Internal Swing Baffle Plates: Internal swing baffles prevent oil surge during cornering, acceleration, and braking — keeps oil around the pickup tube for consistent oil pressure even at extreme angles and G-forces
• Maintains Factory Ground Clearance: Increased capacity is achieved through optimized internal design — the pan does not hang lower than factory, eliminating scraping concerns on driveways, speed bumps, and track curbing
• Oil Temperature Sensor Port (PT1/8): Integrated PT1/8 threaded port for an oil temperature sensor — add oil temp monitoring without drilling or tapping the pan
• Race-Proven Design: Developed and proven on Tomei's N2 series Silvia race car — tested at the highest levels of motorsport before reaching the aftermarket
• Direct Bolt-On Replacement: Direct replacement for the factory SR20DET oil pan — no modifications required
• Made in Japan: Engineered and manufactured in Japan by Tomei Powered — over 50 years of high-performance Japanese engine parts expertise
