This 2007 Lexus IS250 was built by Performance Supercar in Austin, Texas. The company replaced the factory 2.5 L 4GR-FSE V6 and transmission with a 6.0 L LSx V8 and T56 six-speed manual using their swap kit. The motor features a custom 2.75-inch exhaust and a P59 ECU tuned on HPTuners. Performance Supercars was able to retain the factory Lexus PCM, gauges, electric power steering, AC, and ABS. Future plans call for a nitrous system to boost the engine’s output to 600+ horsepower.

I’m in the process of buying a 2007 is250 with a bad motor and I’m definitely inspired by your build. Recently I’ve relocated to Houston, and my question is this: AM I able to swap in a LS3 with your kit? Or am I limited to a LS1? I’m sure that I’ll need to find a tyranny as well, but the T56 6 speed manual is a good start, if not that which do you recommend?
