4 Cylinder Competition "Stage Killer" Engines.
Everyone claims they build the "best" and "highest HP" engines, so there's no need to be a broken record.
What nobody else can claim is that they build the "Best, highest HP" engine that is durable and lasts. If you're tired of finishing last, or not finishing at all, consider stepping your engine program up and letting D.O.A. supply you with a uncompromised build, The "Stage Killer" series says it all in the name............
