i like my 2.5 with 410s an 31s it crawls pretty slow and ive never had an issue with it an its a hell of a lot better on gas than a 4.0

could have been the high kms on my motor and teh 33" claws (they only measured 31" tho) 91 was the changover year for the renix to crysler fuel injection, all in all it could have been alot of factors giving my YJ the shitty gas milage it had. :dontknow: that being said, having driven both 2.5 and 4.0L jeeps the power difference is very noticable... not doing 4000 rpm @ 70km/h up a hill in 3rd gear is quite nice

I've got a '89 XJ Pioneer with the tada Renix injected 4.0 straight 6....from what I've seen so far from it it gets pretty damn good mileage, I'd even dare to say better than my '89 Buick Century with it's 3.3L V6....goes a long long way on $20 which is damn good. All I've done to it since I got it was throw in the plugs and wires the previous owner bought for it but didn't install. that and a bit of throttle body cleaner down it's throat, seems to run like a champ, sips gas for being a SUV...

pull it, piss on it, then go get a 4.0L, wireing harness, computer EVERYTHING from a 91+ and put it in, or you could get creative and make it into a 4.7L

as for jeeps sipping major gas, i fill the jeep up and go wheeling all day, burn mabey a 1/4 tank, you girls need to learn not to stomp on the skinny pedal so hard
