More Info:
If you're building a high HP 4G63 engine and are not sure which cams to run... let us set you on the right path. On the STM Evo RS build, and on all our high HP builds, we use the STM 650 Cams. The RS set the bar for the Evo 8/9 1/4 mile goals with an 8.0 @ 182 and held that record for fastest CT9A for 3 years.

We can drill you with charts and graphs all day, but we strive for the true results that are not just at the end of the quarter, but felt in street driving as well.

Obviously we recommend upgrading your valvetrain, you will need dual springs to run these cams. If you have any questions regarding your set-up, feel free to call us at the shop.

Install Notes:
• Must use dual valve springs
