Is the 2JZ-GTE an enduring motor?
Why is the Toyota 2JZ inline-6 engine a renowned engine in the automobile industry? A brand-new video delves deep into the engine’s internals and explains why it’s so perfect for producing significant power with stock internals.
The engine in the video is essentially the same engine that was in the last Toyota Supra, which is from Papadakis Racing. Its variable camshaft timing on the intake comes from a Toyota Aristo, also known as the Lexus GS in the United States. The remainder of the movie essentially demonstrates how the engine was disassembled, but while doing so, we can see what makes the engine unique. We may thank Japan’s bubble economy for the over-engineered, extraordinarily long-lasting engines that the auto industry produces.
The 2JZ engine is quite durable to begin with because it has a cast-iron block and a closed block. The engine is equipped with bucket-type lifters, which are highly dependable but don’t fit larger camshafts effectively. The number of moving parts is significantly less than, say, a rocker arm system. The head gasket itself appears to be in decent condition for an engine that has been in use for more than 20 years when the head is removed.
Toyota equipped the 2JZ with extremely durable head gaskets and a closed block design, which contributes to the problem. The absence of water openings all around the cylinders makes them incredibly durable. Because of this, tuners can extract a lot of power and boost from the standard internals. Three layers of steel make up the multi-layer head gasket itself. The construction helps create a very tight seal around the cylinder and prevents the gasket from blowing.
For the mechanical types, the rest of the film is pure zen, so relax and take in the teardown above.
