All of the parts you already have will work perfect with this motor. The injectors and throttle body are a big part of the performance. The throttle body we use is the Hesco unit part number HES 9199HFTB. There a lot of different injectors that work on the 4.0 / 4.7 motors. The most common injectors are the Bosch blue top 24 pound out of the 93 -94 Mustang.

I have a 2012 Wrangler Sport. Is it possible to put this in it and replace the V6 that came in it?
