Product Overview

Dominator 4cly B48E B48C B48D B46C and B46D

 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.
