Often Imitated - NEVER duplicated! The Stage 4 Turbo cam has earned a reputation in hundreds of stock stroke applications. Paired to an S400 frame (or similar size), this camshaft will help you move some serious air past 7500rpm on stock displacement engines. Regarded as the BIG STICK of our turbo cam lineup, the Stage 4 is here to knock it out of the park. If you have a ~408" bottom end spinning it in the 6400-7000rpm range, this is also a very good fit. This is the go-to camshaft for 1,000+hp turbo stock block combinations.
Our kit options take the guesswork out and include:
Camshaft only: BTR Turbo Stage 4 camshaft by itself
Steel Retainer Spring Kit with Pushrods: BTR 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:
- DOD/AFM equipped engines will require a conversion to conventional lifters
- 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
