Get the best performance out of your fast street 4G63 engines with the 258° cams recommended for stock turbo or turbocharger upgrade. These cams are ideal for restrictor plate rally 4G63 engines and provide better low to mid-range power and excellent throttle response. Furthermore, for broader power band and improved throttle response, MIVEC is recommended.

• For engines operating up to 8000rpm and 25psi boost, valve spring kit KVS63-BTK is highly recommended by Kelford Cams.
