Stage III Engines are full competition engines. We provide engines for Grand Am series vehicles as well as all SCCA, PCA and NASA classes of competition.
All Stage IV engines are custom designed, feature all upgrades that are allowed by class rules and are created with an open checkbook. Often times these engines cannot see a full- compliment of our upgraded components, and processes, as most of our items defy class rules.

Unlike other companies that will apply boost to a “box stock” engine, we discourage this. Thats simply due to our experience with these engines and the fact that in stock form, they don’t hold up very well and under boost trouble is to be expected. The stock compression ratio is too high, the stock cylinders too weak and the stock cast pistons are paper thin, why would anyone ever apply forced induction to an engine with these issues?? We will not!
In fact, after our experiences we will not build an engine for turbocharging at all, even if it is updated with our components, processes and blessed.
Our experiences prove that these forced induction kits are poorly developed and are nothing more than catalysts for inevitable failures. We make our power the old fashioned way, ALL- MOTOR!
