The cylinder head is crafted from a light-weight, robust aluminum alloy with fantastic cooling performance. Camshafts are created of specifically cast steel and so are pushed by a timing belt. The 2JZ-GTE motor is provided with four valves for every cylinder: two consumption valves and two exhaust valves. Amazing service. https://andresqhwit.blogsumer.com/27769650/not-known-details-about-jdm-toyota-2jz-gte-vvti-for-sale-built-2jz-gte
