No more expensive than any other modern engine swap. You can get standalone controllers for a 3rd gen Hemi just like you can with LS based engines. You can get them out of many different Dodge/Ram/Jeep vehicles.
I suppose it’s relevant to one’s perspective. I have a friend looking to get a JK and do a hemi swap. Seems some kits are junk and the one that isn’t is about $6k, not including the motor or labor. Figure 3-6k for a verified good, low mile (-50k) motor and it sure isn’t “cheap”. To some that probably isn’t much. To me it’s a fortune. *shrugs*Stuka wrote:No more expensive than any other modern engine swap. You can get standalone controllers for a 3rd gen Hemi just like you can with LS based engines.

That's because you need an ECU that will integrate into the JK's existing computer, and all the systems (everything) that is controls, plus every mount that you need, lot of them come with a radiator and such too. It makes it a turn key system. In an FSJ, none of that matters. All you need is the ECU to run in stand alone.tedlovesjeeps71 wrote: ↑Wed Jan 15, 2020 4:49 pmI suppose it’s relevant to one’s perspective. I have a friend looking to get a JK and do a hemi swap.

If you have the trans from the hemi, then all the gears will work as they should. If doing stand alone, you can use a 727. But not sure I would go through all the work to put a hemi in just to keep a 3sp auto.tedlovesjeeps71 wrote: ↑Wed Jan 15, 2020 7:10 pm So do people prefer to keep the TF727 (or TH400) or does the ECU allow the OD auto from the hemi to work too?
How is the progress coming on your swap?
