Considering that the 3.6 was supposed to be like the holy grail boasting higher torque and horsepower it's a total joke .I forgot the last time I was 4 wheeling into the 5-6k RPM range .I agree it performs a little better than the 3.8 but I think most of the performance gains actually come from the 5 speed transmission.
On a side note I test drive the 3.6 twice a year hoping for something I can't live without but it never happens.

It's a new kit, but that aside, Offroad Evolution is now completing the 4.0/4.9 stroker version (on 9-25-13) and rumor has it, that they are looking into doing the 3.8 soon.

I have a 07 JK 3.8 Motor has 165000km on it with no problems. None of the oil leak problems. I have no problems with the power , little as it is , put with 5:13 gears i have enough torque. What i don't have is that power on the freeways going 100km or better. My plan was always going to do a new hemi transmission transplant. Giving it a new power plant and do a frame off resto . A lot of money. I recently seen a aev supercharger install. Very nice and a third of the cost. Now what is the opinion of you's guys on which way to go. The supercharger will have enough power for me as I am a slow cruiser. Or should i be thinking of the hemi and do a total overhaul. Is it worth the extra cash for all that power in the hemi ? Are the guys with the supercharger happy with it. Is the power more then enough for that extra boost on the highway. Thanks for any info.
