This updated version of the BTR Stage 1 Turbo camshaft was designed to be a versatile camshaft that performs well in a wide range of applications. Developed in house, the engineers at BTR went back to the drawing board in search of more power and torque, even with the use of less intake duration. These new BTR lobe designs were Spintron tested to help achieve the highest overall power curve while also maintaining strict valvetrain stability and durability standards.
 
Good for 5.3L and 6.0L engines with cathedral port heads and factory or aftermarket long runner intakes, it also gives great results in LS3 headed applications as well. At the end of the day, if you're hanging a 64-78mm turbo on your LS-based build ,and plan on putting some street miles on it, the Turbo Stage 1 is hard to beat. This is also a good choice for moderate 4.8L combinations, as it will act more like a typical "Stage 2" camshaft in those smaller engines.
