Here is a pictorial demonstration of the 1UZFE engine being apart. Most of the components are stock except one of the cylinders got bored and some experiment with the head chamber.
This awesome machine displacing close to 4.0 liter with double over head cams all aluminum block and heads with electronic multi point fuel injection system.
Due to the need to impress the world with the first luxury car from Toyota. Lexus engineers were out to produce the best of the best from Japan. The block was all aluminum with 6 bolt main bearing caps along with forged steel crank and balanced to zero forged pistons. Secondly, the block is webbed and cross-bolted for extra rigidity.
I believe this engine have the same or perhaps higher quality/engineering than the world famous 2JZGTE, which is powered the Supra MKIV Twin Turbo.
This engine was and is considered one of the best engine ever produced from Japan and perhaps the world. We are looking at a piece or history and a piece of art. This engine would make about 25% more horse power than the 2JZGTE.the forums to get a quick answer or share your experience!
