Product Overview

Dominator 4cly B48/B46/B42

 he JMTCs Dominator turbocharger was designed to give you the most power possible and when we say the most power we mean it.  The Dominator turbo has a huge 56/80mm compressor and upgraded 9 blade lightened high flow turbine to give you the most power possible at the top-end.  If you are looking to dominate the street and strip this is the turbocharger for you.  This turbocharger can flow over 60lbs/min (600hp) @ 30psi so it requires our M101 4” exhaust adapter and a minimum of 3.5” exhaust.
