Mitsubishi Evo 8 GSC Power Division Camshafts (S3 Grind)
The GSC Power-Division billet S3 cams for the Evo 4-8 4G63 are meant for 800+ WHP 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 length. Some cam gears are too thick for the OEM bolt on the billet cams, a 40mm underhead length bolt may be necessary in this case**
