The Black four door wrangler came to us from Seattle Washington. This customer wanted a very impressive motor setup, so we had our friends at Mast Motorsports build a 1000hp rated lsx long block. It has their custom heads on it with a fully forged rotating assembly.
We topped it off with a whipple 2.9 liter supercharger. The engine on mild boost made just shy of 840hp. We backed up this engine with fully built 6l90e transmission running billet internals and a billet custom stall converter. To keep everything cool we installed a Ron Davis oversized radiator running our custom fan setup with a matching engine oil cooler and remote mounted trans cooler to keep all of the components nice and cool.
We also designed a fuel system to support the large demand this motor has and still use the factory fuel tank. The suspension was an Evolution Off road Double throw down kit. Then we put a set of Currie Enterprises RockJock axles underneath to handle the increased power of the newly installed powertrain. We topped of the drivetrain with a set of ALCON brakes on the axles and set of Walker Evans forged wheels.
This is one of our most powerful JKs to date on high boost would be capable of making right under 1000 horsepower.
