1998 Jeep Wrangler Sahara 2dr SUV 4WD


Great auto, it does whatever you want it to do. It has had to have some repairs done to it, but with a vehicle that is designed to go anywhere, things are bound to wear out. The inline 6 is a great engine, the fuel econ is a little low but with knowledge of how the eng works you can improve it dramatically i.e.: a little diesel mixed in the fuel at the right levels sent mine from 16mpg to 20mpg keep the lift low 2.75 inch, run 33inch tires change the trans to an AW4 and I added 4 more now I’m at 23mpg. the last thing I did was use a cylinder cut out at 1200 to 3500 rpm (highway speeds) #2 and #5 drop out that added 5 to 6 more depending on who made the gas, now 29 to 30mpg. Anyone can do it.

If Jeep would make a drop in diesel engine with transmission would make a big difference, you can really make those get some high econ.

This is awesome news ! How can the average person get this done ? I'm looking at a 98 Wrangler right now, but they haven't posted the price yet.
