Building a Powerful Toyota 2JZ Engine from Scratch

The 2JZ is widely regarded as one of the most iconic JDM engines, alongside Mitsubishi's 4G63T and Nissan's RB26DETT. Despite being discontinued due to the focus on fuel efficiency and emissions, dedicated enthusiasts like Mike are determined to rebuild this legendary engine.

Mike's admiration for the 2JZ stems from its robust cast iron block, which enables the Toyota Supra engine to generate an impressive horsepower exceeding 1,000.

Prior to diving into the engine build, Mike carefully considered the components he would utilize for the cylinder head. He emphasized the simplicity of the valve train and the team's decision to enhance power output while minimizing boost. To achieve this, they opted for ported cylinder heads and selected Supertech intake and exhaust valves, which contribute to the efficient functioning of the four-stroke cycle engine.
