The EVO 8 solid lifter 272ø cams are the ultimate performing motorsport cams, specially designed for racing 4G63 engines with a turbo size range of 54-64mm, generating power outputs of 400-700hp. If you plan to use these cams, it's essential to convert to solid lifters as they're not suitable for OEM hydraulic lifters.ÿ
- We recommend using KVS63-BTK valve springs for up to 8500rpm and 35psi boost.
