JE-Pistons Kit Toy 2JZ-GE/GTE (9.0:1) 86.00mm Ultra Series
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
