My friend's uncle came over to his house with his Lexus SC300. He had dropped in a Toyota Supra Twin Turbo I-6 engine and had put 23K into the car. He had Turbo upgrades, a giant Intercooler, intake, water injection with methane, NOS, and computers galor. He dynoed at 643 rear wheel horsepower. He ran an 11.1 @ 130 at the track. His 0-60 is 3.9. He took us for a ride in it and it was the fastest thing I've ever been in. This thing was crazy. He was weaving in and out of traffic at 80mph during rush hour and got it to 155 on the highway before slowing down. It was so much fun and freaking crazy at the same time.

 

sounds very interesting. while at my old job, i installed catback on a big lex 400, and it sounded great. he was thinking about a blower for it. his certainly wasnt that fast, but it was a great looking, very smooth car.
