2012 JK vs Engine swap

Greetings to all

First of all, I would like to say that I am a loyal jeep fan, I had a 94 YJ which I traded for 98 TJ back in 2000. I've done a lot of mods over the years (regeared, air intake sys, exhaust sys, stroked engine, ignition sys, etc) on top of 4.0" lift kit and 33" tires. I can literally say that I took my TJ across continents. I moved from N.C to Kuwait and back to the states. I did a lot of street drag racing (rebuilt a stroked engine twice)... i considered Nitro and Super-charge sys at onetime, but after some research i realized it wouldn't be a good fit for 98 TJ

Now that I'm back in the states, I'm looking for a new or used JK and I want it to be a BEAST when it comes to hp and tq. For that I have a couple of options:

1- Get the new 2012 JK V6 VVT (285 hp 260 tq) and later put on a supercharger
2- Get JK prior to 2012 and do engine swap

I've been hearing mixed reviews on engine swaps. I checked few web sites like http://www.cop4x4.com/ and they claim 400+ hp and tq!! which is very tempting if there aren’t any side effects

Since I ONLY worked on 4.0 I-engines and never did an engine swap, I consider myself newbie on the subject and I seek expert advice.

Which option would you recommend? Or you thoughts in general....

Sorry for the elongation.... my 1st post.... I promise it will get better

Neither engine is a "beast for torque"

Diesel swap?

If you really want that kind of HP and torque, your best bet in the long run would be a new aev jeep with a 6.1 hemi. They also do other mods for a price and it is a turn key deal. Or they can do a hemi install in your jeep also I believe. Even if you do the swap yourself It will not be cheap.

Hmmm. Both sound fun. I almost feel myself leaning to pre pentastar with a hemi swap. Burnsville offers one with a 7.2l hemi. But AEV... I haven't seen a negative review yet. And they now make a kit for manual, and their kits now work with their snorkel.

In order to get the power you're talking about I'd definately get an older JK & start from there. The new (2012) engine isn't going to make that kind of power, ever. No sence in paying big bucks for new & then doing the Hemi swap. Hope you have deep pockets. Love to see what you end up doing, AND.....

These links don't necessarily have the info you're looking for, but may give you some pertinent info on what you're considering.

Why are 392 Hemi swapped Wranglers so slow?
Get a older Jeep and engine swap or buy a newer jeep JK?

Yeah, "beast" isn't going to describe the 2012 3.6 until the aftermarket comes up with a supercharger (which it hasn't yet) and who knows how that'll go. You want a V8 or diesel swap, both of which are available right now for JKs.

I would go with the engine swap if you have the money. The 3.6L is better, but still not a "beast".

Thank you ALL for ur inputs
I'm going with old JK+engine swap... If anyone has a review on Crock Off Road Performance it would be great. I know AEV has good reviews, i just want to compare... beside CORP claim more Hp and Tq (7.2L Hemi)!!


I will be shopping for a used JK (preferably with a lift kit) and i will post pics along the way..





The above pics were taken in the states

http://burnsvilleoffroad.com/ offers hemi conversions for all engine sizes as well. Some say they over heat, but I cannot speak for any conversion, not even based on personal second hand info. The only reason I lean to AEV when I do mine is the adaptability for a (their) snorkel.
