Need a ZJ, have some Q's...

Ok, I know this question has probably been answered a million times but I ran a search and didn't find exactly what I was looking for. So, I don't have a ton of money to spend and I am looking at a 93 or 94 Grand Cherokee. My question is between the I6 or the V8. My biggest concern is with the reliability of the V8 especially in the early stages of the ZJ. I really want the power, but how many miles can you typically get out of the V8? Also I plan to do a mild lift with 31's, will the I6 handle these fine or should I step up to the V8?

Thanks for the help!

Your right this has been answered a million times, but for what it's worth, I had the I6 and didn't like it. I went up to the V8 and have never regreted it. I can't personally vouch for the 93 to 94 time frame but mine runs like a champ...

I was kind of leaning towards the V8 but have also heard that it's not as reliable. Anybody know how long they generally last? I'm looking for a 93 or 94 since thats what I can afford. Anybody with experience from these years? Thanks

I haven't had problems with the reliability of my v8 after 10 years.

Have 96 GC V8 5.2L run 110 000 miles. Nothing done with the engine exept normal service like oil changes etc. My experience from 25 years with engines is that the V8 will be the last part to cave in on this car. Guess it will last at least 250 000 miles. Engines are normaly not the problem. It's the rest of the car falling appart around it....

I have a 93 ZJ with the V8.

So far have had no problems with the ZJ except I grenaded my CV axle. No biggie.

As for the V8, how does 160k miles with no leaks and doesnt burn a drop of oil sound?

That sounds good to me You'd be a good person to ask about gas mileage with the 31s and all. That's what my plans are, so how bad is it?

I have an I6 in my '96 ZJ, and I can say it has enough power for a daily driver, but it would be nice to have more power sometimes. When you push the pedal to the floor, it just dosen't feel like it is going that fast. I just ordered the K&N FIPK, and that should help. I wish I could find a way to adapt the heads and intake system from Chrisler's 3.5L DOHC I6. Intake splits off and goes to two throtle bodies, then one side of the intake goes to every other cylinder. Had lots of power...

Get the V8, you will probally like it...

Like most others said, I would go with the V8. The 318 which is the engine used in the ZJ's rarely has any mechanical problems. I have 143K miles on my 96 and run 31 inch tires. I have driven across the country numerous times, gone off-roading, and it has never failed me. Ask most people what they think of the 318, and they'll say it'll run at least 250-300K miles if properly maintained. The I6 is a good engine, but lacks the power to run a lift and larger tires in my opinion. Good luck with your choice.

On the freeway I can get 20-22mpg and in the city I get anywhere from 9mpg to 14mpg. Usually I'm somewhere in the middle depending on how hard on the gas I am. There was a decent improvement on the freeway from the 235/75R15's when I swapped to 31's. Reduced the effective gear ratio so the mileage improved by about 2mpg.

Thanks guys. You've been a lot of help and I'm really leaning towards the V8 since all of you have had good luck with them.
