The High Speed Engineering Toyota 2JZ-GTE Billet Oil Pump Backing Plate is a precision-engineered upgrade designed to dramatically improve the reliability and stability of the factory 2JZ-GTE oil pump assembly. Manufactured from high‑strength billet aluminium, this backing plate eliminates the flex and distortion common with the OEM stamped-steel plate—an essential improvement for high‑RPM and high‑boost 2JZ-GTE engines.

Designed specifically for performance applications, this billet backing plate ensures the oil pump gears remain properly supported under extreme loads, helping to maintain consistent oil pressure and reduce the risk of premature oil pump failure.

Compatibility:

• Suits Toyota 2JZ-GTE
• Compatible with VVT-i and Non-VVT-i models
• Direct replacement for the OEM backing plate inside the factory oil pump
• Designed for engines retaining the standard oil pump housing, whether OEM or upgraded with billet gear sets

Key Features:

• Billet Aluminium Construction: CNC-machined from high‑grade alloy for superior rigidity and dimensional accuracy.
• Improved Gear Support: Prevents pump housing deflection that can occur at high RPM, helping maintain stable gear engagement and oil pressure.
• Enhanced Durability: Significantly stronger than the OEM stamped steel backing plate, removing a known weak point in modified 2JZ engines.
• Motorsport Grade: Suitable for drag, drift, time attack, and high-boost street builds.
• Direct Fit: Installs into the OEM pump housing with no modifications required.

Why Upgrade to a Billet Backing Plate?

• The OEM pressed steel plate can flex under load, causing rotor misalignment and oil pressure fluctuation.
• High‑RPM events (rev limiter use, missed shifts, drifting, etc.) can amplify this distortion.
• A billet plate maintains perfect gear support, dramatically improving pump stability and lifespan.
• Essential when paired with billet oil pump gears or splined‑drive upgrades.

The High Speed Engineering Toyota 2JZ Billet Backing Plate is a vital reliability upgrade for any high-performance 2JZ engine. Whether for competition use or a high-power street build, this backing plate ensures stable oil pressure and dependable operation under the harshest conditions.

Notes

• It is the engine builders responsibility to ensure that all components are clean, undamaged and free running BEFORE and AFTER installation.
• Gears and backing plates must be assembled initially with clean engine oil or assembly grease. Do NOT run dry!
• These backing plates are direct replacements for standard backing plates. If something doesn’t fit easily, then something isn’t right. You should not have to modify the housing and once installed, the gears should spin freely, with no restriction other than the oil seal.
