263-C
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. Kelford Cams recommends upgrading the valve spring and retainer to KVS263 for up to 8000rpm and 30psi boost.
