GPI LS Turbo Camshaft - STG2 (2010 - 2015 Camaro | 2014 - 2019 C7 Corvette) - TC-STG2
Stage 2 Turbo Camshaft for Moderate-Boost LS Builds
The GPI TC-STG2 is engineered for enthusiasts looking to push their turbocharged 6.0 - 6.2L LS engines into higher power levels while maintaining excellent drivability. Designed specifically for the 5th Gen Camaro and C7 Corvette, this three-bolt turbo cam delivers stronger mid-range torque, sharper throttle response, and faster spooling than the Stage 1 - making it the ideal choice for moderate boost street/strip builds.
With a mild performance idle and excellent road manners, the TC-STG2 provides a perfect blend of streetability and power. When paired with a free-flowing exhaust, proper turbo sizing, and a higher-stall converter, this cam becomes a potent upgrade capable of supporting serious performance goals.
Turbo LS Camshaft Overview
GPI turbo camshafts are industry benchmarks for LS2, L76, and LS3 engines using LS3/L92 rectangle-port heads. Our cam packages have helped push countless 5th Gen Camaros and C6/C7 Corvettes deep into the 9-second range, proving both their power potential and reliability.
The TC-STG2 occupies the sweet spot in the lineup - more aggressive than Stage 1 but still exceptionally street-friendly. It's an excellent choice for drivers who want more power without jumping into all-out race cam behavior.
