Re: TJ engine swap - 4.0 to something with better MPG?
There's room for improvement. Here's a pretty direct comparison between a
Wrangler SE and the Honda CR-V.
Wrangler SE: Curb weight 3235, 147 HP @ 5200 RPM, 165 lb-ft @ 4000 RPM, EPA
city 18, highway 20-21.
CR-V: Curb weight 3258, 160 HP @ 6000 RPM, 162 lb-ft @ 3600 RPM, EPA city
21, highway 25.
The Honda makes more horsepower and the same torque (at lower RPM), but gets
4-5 more miles per gallon on the highway. When you load one up with huge
tires and offroad gear the mileage would certainly drop, but that's almost
certainly not what the OP had in mind with his Jeep.

Re: TJ engine swap - 4.0 to something with better MPG?
There's room for improvement. Here's a pretty direct comparison between a
Wrangler SE and the Honda CR-V.
Wrangler SE: Curb weight 3235, 147 HP @ 5200 RPM, 165 lb-ft @ 4000 RPM, EPA
city 18, highway 20-21.
CR-V: Curb weight 3258, 160 HP @ 6000 RPM, 162 lb-ft @ 3600 RPM, EPA city
21, highway 25.
The Honda makes more horsepower and the same torque (at lower RPM), but gets
4-5 more miles per gallon on the highway. When you load one up with huge
tires and offroad gear the mileage would certainly drop, but that's almost
certainly not what the OP had in mind with his Jeep.

It's all in the transmission and in driveline losses with
conribution from more efficient engine tech.
Even the ZJ got a good boost in power and economy by
introducing a hemholts tuned intake rail rather than the
straight shot like mine has. Heck, I'd like to have the
newer generation 5 speed tranny. Too bad it's not compatible
with the ECU. Stupid pooters. :)
That and the CR-V is more "aero" than the Wrangler.
Not like I fly the most aerodynamic brick either. :)
