JE-Pistons Kit Toyota 2JZGTE 86.5mm 8.5:1(ASY) Perf.Sk

JE Pistons 296932 – forged piston kit Toyota 2JZ-GTE / 2JZ-GE

The JE 296932 kit is designed for turbocharged 2JZ engines that demand reliable power at very high boost. Each piston is forged from 2618-T6 aluminium, machined with JE’s asymmetrical FSR skirt design and protected by low-friction coatings, giving you strength, low weight and excellent ring seal up to—and beyond—four-digit horsepower levels.

Key features

• 2618-T6 forging – high tensile strength to survive extreme cylinder pressures and detonation.
• Asymmetrical FSR skirts – narrower thrust side reduces weight and friction, wider major skirt improves stability.
• Graphite skirt coating – lowers friction and prevents cold-start scuffing.
• 17 cc inverted dish gives a street-friendly 8.5 : 1 compression with OEM 86 mm stroke and stock chamber volume; safe for large single or twin turbos.
• Lateral gas ports (factory option) maintain ring seal at high rpm and boost.
• Thick-wall 22 mm wrist pins included, ready for nitrous or 40 + psi boost.
• Comes with matched JE Pro Seal ring pack and pin locks for a complete drop-in solution.

Typical uses

• Drag, drift and top-speed builds targeting 1 000 + hp
• Street/strip 2JZ-GTE upgrades with big-frame turbos
• Turbo-converted 2JZ-GE projects needing forged reliability

Technical specifications

Kit contents

• Verify valve-to-piston clearance if using cams over 11 mm lift.
• Gap rings to target boost: ≈ 0.14 mm per 25 psi for top ring.
• Use high-zinc 5W-40 or 15W-50 oil and shorten change intervals on engines above 800 hp.

Equip your 2JZ with JE 296932 pistons and build an engine that stays together when the boost gauge leaves the dial.
