VAC Motorsports has specialized in high performance engine builds for nearly 60 years, leading the industry for over two decades since we have started with BMW as a performance focus.
Our stroker kits provide the S65’s reputable natural aspiration with increased, low-rpm power and instant torque throughout its revolution range. We offer two variants: Both in 4.4-4.7L, one for the standard Alusil block so “no machining is needed,” and the other with iron sleeves that “require sleeving” for big boost, forced induction applications.
