I picked up the latest issue of the DuPont Registry and was flipping through when I came across a 600hp Lexus. It's a 1999 Lexus GX300 600horsepower (as they claim). It looks just like a regular GS300 with Fancy wheels. The ad reads "Very rare high performance Lexus. T66 Turbo and intercooler, reinforced transmission, larger piston injectors, pulleys, etc. Custom 19" wheels, 4,800miles.. Over $35,000 invested in modifications. Must Sell $53,000."..... Anyways, do you guys this could be a legitimate 600 horsepower? If so, just imagine that engine in the IS300. Keep in mind that's double the horsepower my stock GS400 puts out..
