The new Brian Tooley Racing Twin Turbo Stage 4 V2 cam was designed for use in serious effort stock stroke applications. Developed in house, BTR's engineers 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 valve train stability and durability standards.
Paired with larger 70+ mm turbos, this camshaft will help you move some serious air. For people with a street/strip 408" bottom end spinning large enough turbos, this new cam can also be a very good fit.
Our kit options take the guesswork out and include:
Camshaft only: BTR Twin Turbo Stage 4 camshaft by itself
Steel Retainer Spring Kit with Pushrods: BTR Twin Turbo Stage 4 cam plus BTR Platinum .660" Dual Spring kit with Steel Retainers, Valve Seals, and 7.400" Chromoly Pushrods, 5/16" x .080" wall
Titanium Retainer Spring Kit with Pushrods: Includes the above, but with an upgrade from Steel to Titanium Retainers
Gasket kit: Includes Timing cover gasket, water pump gaskets, front crankshaft seal and new damper bolt
Note:
- VVT engines will require a VVT delete kit
- If installing in an engine originally equipped with a 1-bolt camshaft, a 3 bolt conversion kit will be required
- DOD/AFM engines will require a conversion to conventional lifters
