Not to start a 2jz vs 1UZ flame war here but:
-The 1UZ was the Lexus flagship engine for their whole line up back in the early nineties. The engine had more money dumped into its R&D than any other toyota engine ever produced... and according to owner reports the engines have lasted as long as 350+k miles... some even more than that.
Where most engines require a scheduled tune up due to burned up gaskets or the like, the 1UZ still could go another 50k miles. The reason the engines are so cheap and you can get htem all over ebay and the junkyard market, is not because sooo many people are doing the pricey turbo swaps, its because the engines outlast the tranny and the body in most cases. THe 1uz is simply the most die hard engine to ever come out of japan, and one of the reasons I bought the car. This may be partly due in part to the LOW compression of the 1UZ, or so I've heard. the 2jz is a higher compression engine, and its power output was near that to the 1UZ in some production years of the SC's and allegedly its true output was masked by lexus as not to hurt the sales numbers of the SC400... it(the 2jz) is a "higher performance" engine but does not touch the reliability of the 1UZ. Now a turbo jz vs a turbo UZ, is a different story....
Also that car in the picture belong(ed) to CamberSC I believe... and the car was sold a little while ago...

"The 4.0 L (3,968 cc/242.1 cu in) all-alloy 1UZ-FE debuted in 1989 in the first generation Lexus LS 400/Toyota Celsior and the engine was progressively released across a number of other models in the Toyota/Lexus range. The engine is oversquare by design, with a bore size of 87.5 mm (3.44 in) and stroke of 82.5 mm (3.25 in).[1] It has proved to be a strong, reliable and smooth powerplant with features such as 6-bolt main bearings and belt-driven quad-camshafts. The connecting rods and crankshaft are constructed of steel. The pistons are hypereutectic.
It's resemblance to a race engine platform (6 bolt cross mains and over square configuration) was confirmed in 2007 by David Currier, vice president of TRD USA, stating that the 1UZ platform was based on CART/IRL engine design. It was planned to be used on GT500 vehicles, however its subsequent use in the Daytona Prototype use was not planned.
The 1UZ-FE was voted to the Ward's 10 Best Engines list for 1998 through 2000."
also:
"The SC 400 débuted on June 1, 1991 in the United States as a 1992 model. The SC 400's 4.0 L V8 1UZ-FE, the same engine as used in the LS 400, was reported to have cost over $400,000,000 in research and development.[3] The SC 400 was honored as the Motor Trend Import Car of the Year for 1992. It also made Car and Driver magazine's Ten Best list for 1992 through 1998."
and:
"The original 1991-97 engines were rated at 225 hp (168 kW)/210 lb·ft (285 N·m) for the 2JZ-GE-powered SC 300. However it is speculated that Lexus underrated the power of the SC 300 as to not cut into the sales of the SC 400. Dyno testing results have shown the SC 300 to produce around 240 hp"
