I wonder how the 3.6 and 2.0 would compare in regards to 37-40 inch tires. The 3.6 has ore horsepower but the 2.0 has more torque and the power really kicks in at 3,000 rather than 4,800 with the 3.6.
The 2.0 may actually be the better option based on that information. Additionally the 2.0 can probably be chipped for a 20-50 hp gain.
I'm really interested in the 2.0 turbo. I never owned a turbo engine till I bought a Focus RS. I know they are totally different but wow turbos are great. Lots of power almost no lag.......along with the BSG system i think the low end will be great and crusing along in 8th gear should sip fuel, unless it needs to be in boost all the time to keep the Jeep moving.......I've had a JKR, JKUR, and a WK2 all with the 3.6 and I really like it but at higher elevations I think the 2.0 turbo would lose less overall power then the 3.6 NA motor. Depends on cost a bit too.....I'm sure the diesel would be great but I'd rather stick with gas.
Been running fairly heavy 76lb 35s for 18 months.. no issues still very quick ... engine has been great... other issues with steering transmission and water pump.. but engine was solid... very noisy especially when cold.. but pushes the 35s around just fine
I have 35” Milestar Patagonias with Rock Monster rims. Wheels are about 110lbs a piece. My 2.0 non-etorque pulls them around no problem with factory 4.10 gears.
