It was loud and abrupt, in other words
Pollard Jeep in Boulder, CO will do 4BT Cummins as well as HEMI swaps on a CJ, YJ, TJ, and JK. Thing is the 4BT is not technically emissions certified..."Trail Use Only". However, if one lives in a county that does not do emissions certifications then who is to know? There would be really nothing stopping you other than the $21,500.00 cost of the swap, but that does include engine, transmission, other parts, and labor.
Of course, I did not have any type of camera with me. This picture come from the dealers website.
