We had an opportunity to build an awesome IS300 for a client that went from stock auto to 400HP 2JZGTE VVTI and 5 Speed Manual in a matter of a couple weeks.  A custom single turbo kit powered by a Precision turbo feeds a custom front mount intercooler.   The car also has suspension upgrades, a jdm black interior, and upgraded brakes.  The car runs amazing with cold ac and the noise and power of a Supra!
