The High Speed Engineering Toyota 2JZ-GTE Billet Oil Pump Upgrade Kit is an advanced solution designed to eliminate the known weaknesses of the factory 2JZ-GTE oil pump. Engineered for high‑RPM stability, improved durability, and maximum reliability, this kit replaces the fragile OEM sintered gears with precision‑machined EN26 billet steel components. Combined with a splined crankshaft drive system, it delivers exceptional strength suitable for high‑boost, high‑power, and motorsport applications.

Designed specifically to address the common oil pump failures seen in tuned 2JZ-GTE engines, this kit dramatically improves the strength of both the drive system and internal gearset—making it one of the most critical upgrades for any serious 2JZ-GTE build.

Compatibility:

• Suits Toyota 2JZ-GTE
• Direct fitment for both VVT-i and Non‑VVT-i variants
• Compatible with OEM or aftermarket front timing covers
• Replaces standard 2JZ oil pump internal gears with high‑strength EN26 billet gears

Key Features:

• EN26 Billet Steel Gear Set: Significantly stronger than OEM sintered gears, providing superior resistance to shock loading and high‑RPM harmonics.
• Splined Drive Adaptor: Converts the factory flats to a positive‑locking splined engagement, eliminating the risk of drive failure at high engine speed.
• CNC Machined Components: Each gear and adaptor is precision-machined for perfect fitment and reliable operation.
• High‑RPM Stability: Designed to maintain consistent oil pressure and prevent pump gear fracture at elevated rev limits.
• Motorsport‑Ready: Suitable for drag racing, circuit use, drift, and high‑performance street vehicles.
• Direct Replacement: Installs inside the OEM pump housing, improving strength without requiring external modifications.

Why Upgrade the 2JZ Oil Pump?

• The OEM 2JZ oil pump gears are sintered and prone to shattering during over‑rev, limiter abuse, or high‑horsepower operation.
• The factory flat‑drive crank engagement is a known stress point, often rounding off or breaking under extreme loads.
• Billet gears and splined drive components eliminate these risks and provide long‑term reliability.

The High Speed Engineering Billet Oil Pump Upgrade Kit is an essential reliability upgrade for any high‑performance Toyota 2JZ build. With greatly improved gear strength, a positive‑locking drive system, and precision engineering throughout, this kit ensures dependable oiling performance even in the most demanding motorsport conditions.

Notes

• It is the engine builders responsibility to ensure that all components are clean, undamaged and free running BEFORE and AFTER installation.
• Gears must be assembled initially with clean engine oil or assembly grease. Do NOT run dry!
• With the inner and outer gear sitting in front of you and the nose/seal diameter facing toward you, the outer gear should be laid over the inner gear with the “wave” profile in a clockwise orientation. The 2 wave “points” should be facing in the same direction (see assembly instructions).
• These gears are direct replacements for standard gears. 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.
