280°/286° Stage 3 drag racing cams for professionally built turbocharged 2GR engines. Suits single 76mm+ turbo or twin turbo setups in the 58-68mm range. Suited to engines making 1200-1600hp. Great with 4.0L stroker builds. Can maintain use of VVT-i with careful valve to piston clearance checking, otherwise use with fixed cam timing. Great with E85 or methanol.
