The Billet S3 Cams for the Evo 4-8 4G63. These cams are meant for the 800whp+ to take advantage of a very large turbo. These are NOT suggested for anyone running smaller than the 67mm to GT42R turbo.
**If using aftermarket cam gears(especially AEM) check the bolt lenght, some cam gears are too thick for the OEM bolt on the Billet cams, a 40mm underhead lenght bolt may be necessary in this case**
