BTR LS Stage 2 Turbo Camshaft V2 | BTR-TURBOSTG2
The Brian Tooley Racing LS Stage 2 Turbo V2 camshaft is designed for turbocharged Gen III and Gen IV LS street-and-strip engine combinations. Developed in-house with BTR lobe designs and Spintron testing, it updates the earlier Stage 2 formula with less intake duration while targeting a stronger overall power and torque curve. Ships fast across Canada and the US.

Use the cam card supplied with the actual camshaft for final assembly and degreeing. BTR notes that actual specifications may vary; its downloadable card rounds valve lift differently from the product-page specification. Do not substitute the earlier 226/231, .610/.608-inch grind specifications for this V2 cam.
Turbo Build Selection
BTR describes the previous Stage 2 as a proven choice for cathedral-port 5.3L and 6.0L turbo builds, and positions the V2 for a broad range of street-and-strip combinations. Its examples range from a 7275 turbo to a BorgWarner S485; these are build-planning examples, not a guarantee that every turbo and engine pairing will behave the same way.
Choose the cam around displacement, cylinder heads, compression, turbo sizing, exhaust backpressure, transmission and the desired operating range. No fixed horsepower gain, spool speed or stock-like drivability is promised.
Installation Planning
Have an experienced LS engine builder verify clearances, valve-train geometry and the required supporting parts. Engines equipped with variable valve timing or cylinder deactivation require a compatible conversion strategy where applicable; confirm the necessary parts before disassembly.
This listing is for the camshaft, not a complete cam-swap kit. Springs, pushrods, lifters, timing components, gaskets and fasteners should not be assumed included. Follow BTR's installation instructions and arrange the appropriate calibration before operating the finished turbo combination.
