Is putting a Hemi in worth it?

So for those out there who are running 35+ tires with a lift and a Hemi on a 4 door JK. Is it worth it? How much did it cost? What's the gain in power and mileage (if any). What's your lift, tire size and gears? I have a 4 door 2009 with the mini van engine and I'm just wondering, is it worth it? Thanks.

why not put in a RIPP for a lot less money and hassle?

To me the $20,000+ cost is not worth it (Cost to have AEV install it). If your eng is good and not burning oil you would probably be better off with the RIPP supercharger.

How hard is that to install or would you recommend a shop? Anyone have a Ripp and what are your specs and results? That is a LOT less expensive way to go.

Thanks,
Mike

There a few threads on here about them. From what I've read, they are very happy with it and took a day to install. Only one I've seen in person was on a TJ and is was impressive t watch it wheel.

Mileage? This strikes me as a strange question in this context.

I agree with going with the super charger. If your going to do a Hemi swap you might as well buy another Jeep with the Pentastar and move your after market parts over to it.

IF I had the dollars, and I knew it would pass TX inspection, I would be all over a Hemi or an LS conversion. RIPP is a great way to go to, and a lot less hard on the wallet. And it would sound AWESOME as well.

I have a quote right now that's in the 8-10k range with motor, labor, and transmission rebuild. This is for a TJ though, but I can't image the JK would be any higher.

Add about $5k for a JK. Having the Hemi (or LS) interface with the factory electronics (Canbus) is an expensive package. AEV does one, so does Burnsville. MoTech and JSS do one for the LS motor. They're all +/- $5k.

OP, I wouldn't bother with supercharging it. Comparing a blown V6 to a V8 is apples to oranges. Folks seem to think that because the peak horsepower is close to that of a V8 they'll perform the same. Best to look at dyno sheets for both. Look at the way the torque is delivered and where horsepower is made and you'll see what's best.

Also, I would definitely look into an LS swap rather than a Hemi. Much better motor and transmission.

Lol, yeah right. JK prices for everything on average is about 150% more than a TJ due to the market demand. V8 swap for a JK is ball-park $15,000-20,000 depending on the way you go about it.

Absolutely correct! Peak horsepower is not an indicator of engine performance. No matter what you bolt onto a V6, it still ain't no V8.

I agree but... when you can get close with a RIPP and are into it for under $5K and the V8 (on the lower end) would be into it at $15K... close is good enough for me! I don't mind eating a apple when everyone else is eating a orange...
