JE Pistons Ultra Series 361341 – forged piston kit Toyota 2JZ-GTE / 2JZ-GE

The JE 361341 set represents the top tier of JE’s Ultra Series—pistons engineered for extreme boost pressure and sky-high RPM in the legendary 2JZ platform. Forged from 2618-T6 aluminium using Aligned Grain Flow technology and protected by advanced thermal and low-friction coatings, they deliver bullet-proof reliability at power levels far beyond stock limits.

Key benefits

• Aligned Grain Flow forging guides material fibres to follow the piston’s load paths, maximising fatigue strength under high boost.

• Ceramic-thermal crown coating reflects heat back into the combustion chamber, lowering piston temperatures and improving scavenging.

• Graphite skirt coating reduces friction, cold-start noise and cylinder-wall wear.

• Lateral gas ports on the top ring land maintain ring seal at high RPM and boost.

• Trend Performance wrist pins Ø 22 mm, thick-wall, ready for nitrous and big-boost abuse.

• Matched ring pack included—profiles and tensions tailored for turbo, ethanol and high-output builds.

Typical applications

• Drag, top-speed and pro-drift engines exceeding 1 000 hp

• 2JZ-GTE street/strip builds using large single or twin turbos

• Turbo-converted 2JZ-GE swaps replacing fragile OEM cast pistons

Technical specifications

* With OEM 86 mm stroke and 2JZ-GTE combustion chamber.

Kit contents

• 6 × JE Ultra Series pistons 361341

• 6 × Trend Ø 22 mm wrist pins + locks

• Complete ring set 1.0 / 1.2 / 2.8 mm

• Installation guide with clearance and torque data

Installation notes

• Maintain minimum 0.10 mm piston-to-wall clearance for street use; increase per JE chart for race/boosted setups.

• Verify valve-to-piston clearances on lifts ≥ 11 mm; machine pockets if required.

• Gap rings to match target boost (≈ 0.0055″ × bore for high-performance street, 0.0065–0.0070″ for > 30 psi).

• Run high-zinc 5W-40 / 15W-50 oil and shorten change intervals on 800 hp+ engines.
