Thanks for the info. Think i will keep looking for a 4.0L
I have found some cheap 4.2l but like mentioned they either aren't running or "needs work".
The article in Petersons had some good info in it for what to look for or avoid.

 

i have every thing to put a4.0 in a jeep i mean everything

 

hes got everything lol

 

deffs get a 4.0l fuel injected they are indistructable and have plenty of tourque for those hill climbs. i have a 1995 yj with the 4l with 277000 km and it still runs like a champ! i get about 300-400km on a tank with 33x12.5 tires so not to bad on fuel.
best 5000 dollars ive ever spent!

 

tha 4 cyl is deff a good motor scooby pounds his all the time and still going strong

 

Can't say from personal experience. I've only had 6 cyl., but an friend has a 4 banger and wishes he had a 6. He says that it is ok but looses power on hills and is pretty anemic if pulling something.

 

I have a 94YJ with a 4L HO 5 speed and if u can find one I would take it over the 4banger or an older carb. YJ. It runs good and doesn`t break down. Find urself a 1993,94 or 95 the last year it was built..
