The cylinder head is fabricated from a lightweight, sturdy aluminum alloy with fantastic cooling performance. Camshafts are made of specifically cast metal and therefore are pushed by a timing belt. The 2JZ-GTE engine is provided with 4 valves for every cylinder: two intake valves and two exhaust valves.
