The Lexus GS430, typically known for its refined luxury, received a thrilling transformation by Blitz for the SEMA show. This sleeper, cloaked in a subtle custom body kit, harbors a secret under the hood: a Blitz supercharger boosting the V8 engine’s output by 73hp to a total of 363hp.
Unleashing the Beast: Performance Enhancements
The heart of this GS430 Blitz build lies in its supercharger system. This prototype twin supercharger, equipped with an electronic clutch and a console-mounted selector switch, offers three settings: off, low, and high, allowing the driver to control the boost on demand. A performance monitoring system, integrated with the navigation screen, provides real-time data on the enhanced engine’s performance.
Complementing the supercharger, Blitz incorporated several performance upgrades:
- Blitz Sonic Power Air Cleaner: An adjustable velocity stack intake with a cotton fiber filter optimizes airflow for increased power.
- Blitz Iridium Spec 77 Spark Plugs: High-performance iridium spark plugs with a heat range of 7 ensure efficient combustion under increased boost.
- Blitz Nur Spec DT Exhaust System: A full stainless-steel exhaust system with a dual rolled tip enhances exhaust flow and adds a sporty note.
- Blitz Radiator Cap: A high-pressure racing radiator cap (18.4 psi) maintains optimal cooling under demanding conditions.
Tech Savvy: Electronic Upgrades
Beyond raw power, the GS430 Blitz boasts several electronic enhancements:
- Blitz RVIT DS (Prototype): An OBD2 port reader with limited CAN BUS control, utilizing the factory navigation screen to display vital ECU information.
- Blitz TV/NAVI Jumper (Prototype): Allows for DVD and auxiliary input viewing while the vehicle is in motion.
- Blitz Power Meter i-Color: This device measures horsepower up to 1200 hp, with peak hold, warning, and recording/replay functionalities.
Handling and Style: Suspension and Exterior Modifications
The performance upgrades are complemented by a lowered stance, courtesy of Blitz Super Flex Lowering Springs, providing approximately 1.0″ drop in the front and 0.75″ in the rear. The car sits on Blitz BRW Profile 09 wheels: 20 x 9 +38 with 245/35/20 Falken FK-452 tires in the front, and 20 x 10 +40 with 275/30/20 Falken FK-452 tires in the rear. The deep chrome finish adds a touch of aggression to the sophisticated exterior.
A custom exterior package completes the transformation:
- Blitz Carbon Fiber Front Grill with Emblem Base: Adds a sporty touch to the front fascia.
- Blitz Front Lip Spoiler: Improves aerodynamics and enhances the aggressive look.
- Blitz Side Skirts and Rear Valence (Prototype): Further refine the car’s aerodynamics and visual appeal.
- Blitz i-Burner Illusion LED Lights: User-controlled LED lights with multiple color outputs provide a customizable lighting experience.
