Description

The BigBoost GTX800 is a comprehensive turbocharger kit engineered for N55 F-Chassis vehicles, offering significant performance enhancements. This kit features a Twin Scroll Manifold with 1.5″ runners, designed to optimize exhaust flow for all six cylinders. At its heart is a genuine Garrett GTX3582R Gen2 turbocharger, with an option for the GTX3584RS (GTX1000) for even greater performance. The kit includes a robust set of components for reliable operation and easy installation. You'll find 4-Ply Silicone hoses, V-Band clamps, Aeroquip branded coolant and oil drain hoses, a hard pipe for the cooling system, and a billet aluminum intercooler coupler. It also comes with a VTA DV system, a boost pipe, and a 2-piece 3″ turbocharger inlet. Stainless steel braided AN lines are used for oil feed, complemented by a stainless steel oil feed line and a turbo oil drain coupler, along with all stainless steel hose clamps. A Turbosmart/TiAL 38mm wastegate ensures precise boost control. BigBoost emphasizes the rigorous testing and quality of their kits. In-house testing, including measurement of individual cylinder EGTs and back pressure, has shown the kit operates within safe and ideal back pressure ratios of 1.11-1.12:1. This kit has been proven in endurance racing, running for 6-12 hours with excellent results. BigBoost also prides itself on exceptional customer support and provides tuning advice, with options for custom maps. Notably, the water pump does not require relocation, and the OEM RH engine mount bracket is retained for RWD applications, simplifying installation. All major components are proudly made in the USA or sourced from South America, avoiding Chinese parts. Users should consult the provided Fitment Guide before ordering, as specific drivetrain configurations (RWD or X-Drive) affect compatibility and pricing.
