When you want to buy quality at a value price, give SAG a call. Tired of dealing with engine shops who deliver sub-performing engines or parts dealers who have no hands on experience in engine fitment and assembly, give SAG a call. We have years of hands on experience and practical knowledge when it comes to machining, assembling, and dyno testing custom engines.

We are a full-service machine shop offering products and services custom tailored to individuals who value excellent customer service from an engine building staff that understands what it takes to build an optimum performing engine at a fair price. We specialize in high-performance custom engines and parts that are unique from what you will find in your average "generic" kit peddled throughout the internet.


We offer better performing engines and parts because we study each engine application and implement the proper parts and procedures that will maximize performance, gaining for the customer value and excellence.
