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

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.
