Get the best performance out of your fast street 4G63 engines with the 258ø 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 KVS63-BK is highly recommended by Kelford Cams.
