SPA exercises complete control over the entire manufacturing process from a well-staffed design team to their own casting foundry. There, using only the strongest, most durable alloys, SPA Turbo manifolds and hot housings offer a superior alloy to GG-40 incorporating a unique blend of molybdenum and aluminum to improve the fit, finish and heat resistance of each casting. Each application is custom designed using state of the art fluid dynamics software to utilize the strength and reliability of cast iron while providing the flow characteristics of a tube manifold. This process is exclusive to SPA and is used in more than 200 turbo manifold castings for cars and light trucks.
Along with their manifolds, SPA is known for building other turbo-related components with the same attention to detail and design-to-foundry execution. Specialized ancillary parts such as SPA’s 90 degree Universal Downpipe, T3 Turbo Housing, Wastegate Valves , Fuel Pressure Regulators, Blowoff Valves and Turbo Gasket Eliminator are the leading components SPA and DEI provide to complete the installation of SPA manifolds.
