This is a basic place to gain knowledge of the Toyota Lexus UZ engines including the 1UZ-FE, 2UZ-FE and 3UZ-FE. I don't think I even have read this page until now. It's a great little collection of facts to quickly give you the rundown on each of the engines and what vehicles they were available in at the given time they were on the market.
Nice quick information on the 1,2,3UZ-FE engines:
