Product Overview

Dominator 4cly B48C

The 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 a minimum of 3.5” exhaust.

Requires 3.5" exhaust no exceptions, do not call and ask if you can use a smaller size exhaust or down-pipe, you can not!  All exhaust component have to be 3.5" or larger from the turbo flange to the tip of the exhaust or the turbo and/or your engine can be damaged due to low exhaust flow.
