The IS300 was brought into the mainstream in 1998 and the phenomenon known has “Altezza lights” were born. Sprung from the Japanese nameplate of Altezza, the IS300 brought the non turbo 2JZ into the luxury line of Lexus. Many people opt for the standard 2JZGTE engine swap, while others retain the W55 transmission and simply turbocharge the 2JZGE.

While the Altezza light craze has died down thankfully, these cars and motors are still in abundance. Perfect for the luxury sports coupe enthusiast, the IS300 ECU Pinout is what you need for piggyback computer like an Super AFC install or gauges.
