Yeah I found a mint (for MN) renix XJ. I surprised plenty ricers with my other one on 31s



How in the hell does a 5.2 get better mileage than a 4.0?

That's a nice looking rig! My first Jeep was a totally beat 97 ZJ that was owned by several soldiers at Fort Drum and sold before their deployment. I should have known better, but the price was right. I bought it for $1500 and a year later, I had about $3500 invested in repairs. I had to put a transmission, rear axle, front hubs, ball joints, and brake calipers on it.

I know! Stupid! I was smitten with her looks. It was like choosing a high-maintenance wife! I finally had to "put her down" when she started tearing the lower control arms out of the frame. They don't call Syracuse the "Salt City" for no reason. The city itself doesn't even mix sand with it, because it plugs storm drains. EVERY year, they have to resurface the bridges because of the concrete spawling and cracking because of the salt, not to even mention the rusting of the steel! Just this past winter they switched to brine which soaks in even worse.

BTW, I never had a problem with the 4.0 or NP/242 transfer.

Same here, that's why I nearly pissed myself when the guy read off fulltime. I can't remember if I posted a picture of it or not.

IDK if you use automatic car washes or not, but if you do, make sure you choose the under-carriage option. It helps a lot. Just the simple matter of rinsing off the salt is good.

Mileage begins with the right foot.

I never had a reason to before but I will definitely have to start.

how is the 5.2 more reliable? its the same motor as a 5.9, just with smaller holes punched in it.

That's very true...you really can't tell any differences just looking from looking at the 5.2 and 5.9...they share the same block but the 5.2 has smaller heads and I think a smaller crank

dave1123

Just like Chevy small blocks. You can't tell by looking at them unless you know what to look for. Even then it's difficult. The small block went from 265 cu in to 350 cu in with everything in between.

I think the 5.2 would be more reliable because it's less highly stressed with smaller, lighter pistons and less reciprocating mass. JMHO.

MCosta

That's a good point about the 5.2...didnt think of it that way

dnuccio

true, but the difference in reliability is negligible. my buddy has a dodge truck with the 5.9 (same motor they put in ZJs) and its got over 300xxx miles on the original engine.

I did state that it was just my opinion.
