What's the cost difference vs power of a supercharger compared to a hemi swap?

 

Ripp supercharges have kits for both 3.6 and 3.8 JKs. Cost around 5000 - 6000 US

Say I baught a junk yard hemi out of a wrecked dodge what would I need as far as wiring and computers and could I do it myself with the help of my friends dad who's built trucks for baja many times?

 

Make sure you get the appropriate hemi for your application. There is also a few companies that will sell just the kits needed, including all the wiring, radiator, motor mounts, etc. AEV and BOR both make kits, although I've heard more than a few horror stories from Burnsville Off Road.

 

Biggest challenge I have heard is getting a radiator that will both fit and cool that big engine in a JK

 

Just the kits to swap in a hemi or LS motor are like $5000. There is a lot more to it than just sticking a v8 under the hood.

 

Having owned hemi trucks before I will tell you that dodge waaaaaayyyy over rates these engines. No way do they have a such inefficient drivetrain that they lose 40-45% at wheels. That was big talk in dodge forums when I was part if those. When I test drove a 2011 hemi vs a 2011 ecoboost. The hemi having better gear (3.92 vs 3.73) that ecoboost would eat that hemi for breakfast despite be down by almost "30" hp. I wasted my dads 6.0 chevy my bros tundra a couple of hemis and the only one that came close was my bros titan (nissan underrates those. They closer to 390hp) til I hit third gear. So I say get a supercharger and don't waste money on the hemi swap
