Brand New Gray FAST LSXRT 102mm Polymer Intake Manifold #146602 & Cable Operated 92mm FAST Throttle Body #54095 (with TPS), designed for Cathedral Port Heads in a GM LS 4.8L, 5.3L or 6.0L V8 Truck (or car without hood clearance concerns). FAST Kit Part #146602TB.
Manufacturer's Description (Intake):
Designed specifically for GM 4.8/5.3/6.0L cathedral port truck engines and cathedral port LS1, -2, -6 race applications where hood clearance is not a concern, the FAST™ LSXRT™ 102mm Intake Manifold follows the path chartered by the original FAST™ LSX™ Gen III Intake by featuring a modular design that allows for easy porting and disassembly and a runner design that yields as much as 25 peak horsepower gain over the stock intake. And similar to the LSXR™ 102mm Intake Manifold for cars, the LSXRT features the ability to remove individual runners for modification.
Manufacturer's Description (Throttle Body):
When it comes to improving your engine’s performance, increased airflow is a key ingredient. The FAST™ Big Mouth Throttle Bodies™ for the FAST™ LSX™ 92mm Intake Manifolds increase airflow through a series of innovative design changes and a slightly enlarged throttle opening. FAST™ also invested significant testing & engineering resources into optimizing cross-sectional flow and eliminating airflow turbulence, especially at part throttle operation.
In addition, these throttle bodies offer increased throttle blade thickness to eliminate deflection commonly found with other throttle bodies, especially those in boosted applications. A smoother operating offset blade pivot improves throttle response, and a beefed up linkage and dual throttle spring mechanism ensure total throttle control. The FAST™ Big Mouth 92mm Throttle Body™ will deliver bolt-on GM Gen III (LS1, -2 & -6) horsepower.
