Wiseco has taken its proven 2JZ piston designs and combined the best features from each, along with new technology, to create the strongest extreme duty 2JZ pistons on the market. At the core of this updated design is a newly developed full-round forging, engineered in-house specifically to handle the demand of extreme cylinder pressures seen in 1,500hp+ 2JZ builds. Additionally, these pistons are built to support aluminum connecting rods right out of the box—no additional machining required—and now utilize a 2.5" long wrist pin, which has proven to offer optimal pin capture and increased durability. Designed for serious power and reliability, these pistons are built to handle the extreme demands of any high-performance 2JZ build.
