Note: Please note that the only difference between Evo 8 and Evo 4-7 cams is the diameter of the bolt hole in the back of the exhaust cam; For the Evo 4-7 it is 8mm, for Evo 8 it is 12mm. These cams suit the 12mm bolt so engines with 8mm bolt will need to purchase 12mm bolt separately.
The Kelford Cams range of camshafts for Mitsubishi 4G63 DOHC engines are renowned worldwide for their superior results. This range is for Evo 8 engines with a solid lifter conversion. All of the camshafts in this range are ground on our Toyoda CNC masterless cam grinder to consistently deliver the highest quality product.
Due to popular demand, we now offer a range of catalogue designs to cater for 4G63 engines with a solid lifter conversion; this range is ideal for those serious motorsport applications where use of aggressive limiters for launch, shift and anti-lag may cause hydraulic lifter pump up.
We have developed a proven range of camshafts for this engine to suit most applications. However, if you can't find your perfect camshaft within our range, designing custom profiles is our specialty! Simply order the custom camshaft and provide us all the details of your build. Custom one off confidential development for race teams is available. We can also manufacture to your specifications.
