Lexus IS 300 with TT V8 conversion hits the dyno

Just a humble first-generation Lexus IS 300 laying down some figures on the dyno… We should mention the regular 3.0-litre 157kW six-cylinder has been replaced with a twin-turbo 5.3-litre Vortec 5300 LS Chevrolet V8, equating to a monstrous 861hp (642kW) at the wheels. Check it out. We love the neat little wastegate pipes just above the front wheels.
