These Stage 1 performance cams are the perfect fit for turbocharged 2GR engines. They work well with a single turbo of 58-68mm or twin turbo setups in the 48-58mm range producing 500-700hp. You can expect a significant boost in mid-range power compared to OEM cams while keeping the full use of VVT-i for good throttle response.

However, for engines running at up to 8000rpm and 30psi boost, it is essential to upgrade the valve spring and retainer to KVS263 – a recommendation by Kelford Cams.
