ok guys I got a 2008 automatic jk. I was looking to get a super charger but was told that it wouldn't really matter if im in a area where the temp exceeds 80 degrees. so im looking in doing a v8 swap, also because it cheaper too. but I couldn't find anything about people doing a v8 swap on a automatic, and what engine to use. is it possible to do it, what would I need and how much would it set me back.

I have a friend who runs the RIPP supercharger. He says it made a big difference. Not sure why 80° would matter, but if it's because of lower compression at higher temps, consider RIPP's optional intercooler. That will still be a lot cheaper than the commonly opted V8, a 5.7L Hemi, which I believe runs $15K+ with an AEV self-install kit.

Edit: Here is the AEV install kit. Of course you still need a motor.

Edit 2: RIPP SC with intercooler.

Supercharger all the way. V8 swap done right is $$$$$$ compared to the supercharger. The whole 80 degree thing is BS. Most vehicles pull air from the engine compartment which is 200+ degree air to begin with.

Thinking of dropping the $ on Ripp as well...subscribed for more opinions

Check out "MoTech" for GM LS V8 swaps www.lswrangler.com/

I think it may run $15,000-$20,000 depending on 5.3 liter, 6.0 liter, tap shift, etc.

Can check out Jeep Speed Shop also. Believe they are cheaper on V8 swaps. Not much but money saved is money saved

First off, what gears and size tires are you running? One of the most overlooked mods is a gear swap as it'll make a world of difference. There's a shop in nj doing ls 5.3/6l80 swaps starting under 15k and around 11.5-12k if you supply your own drivetrain. Don't really know where your located but if you have the coin and don't plan on selling it I'd do the v8 swap. I love the 3.8 but you'd be polishing a turd.
