I was planning to swap my stock camshafts for the Kelford 214-B Cams which is compatible with my GTS's 4b12 engine and comes from and EVO X. Now, I have been doing some reading and most places online said that it is made for between about 400-600 HP builds. I only have somethings installed and I know I'm definitely way below that range. I was wondering if this swap would be a good investment and would produce more horsepower. Thanks!
