4 vs. 6

[crawlin92]

Ok... ever since I bought the money hungry black beast of a Jeep I have been thinking about swapping from the mighty 4 banger to a 6 cyl.... well I have a few Q's about it...

1. Whats it gonna take? Obviously the motor, ecu, wire harness... but what else? Am I going to have to relocate mounts?
2. Whats it gonna do to my gas milage? Right now I get pretty shitty, bout 13mpg turning 31's. I would imagine th six would get better due to less work to turn the tires...
3. Will the six turn 33's fine if I decided to go bigger down the road? (this would be once its not a daily driver so gas milage wouldnt be an issue anymore)
4. What 6cyl to get? I already have a 6cyl bell housing and tranny...

I dont think th 4 banger is gonna last much longer.....

you'll need a transfer case too, unless you are planning to rebuild it with an input shaft to acccept the ax15 transmission.

if it is a manual trans [ax15] the 4.10 gears from your 4 cyl jeep will work well with 33 inch tires. if it is an auto.. you'll want 35" tires. otherwise a regear is something to consider.

gas milage will be about the same, but the driving experience will be much more fun.

Hmmm... the tranny is still an AX-5, says it came outta a 93 wrangler? 6cyl. The only difference was the bell housing, the clutch lines and what not all came in the drivers side so I had to get a clutch line from the 93 6cyl.

My biggest question though is about the mounts... are they going to be the same?

New mounts, in different spots. And the AX-5 from the 2.5L is now junk, the 4.0L comes with an AX-15 instead.
