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?
Hi Jason. We recommend contacting Performance Supercar directly to answer your questions.
Hey Jason. Just seeing if you ever got an answer to your previously mentioned question. Take care!
How much is a ballpark figure for this? Do I provide the chevrolet crate engine? Asking for a 2008 Lexus IS250 6AT….
Hi Jonathan. Please contact Performance Supercar for an estimate.
Will do by the end of the 2023 year. Thank you.
