whats the difference between tj & yj engine? i bought a 2.5 from a 94 yj and than a local jeep guy told me that it wont work in my 01 tj. both had 2.5l-or so i thought- both had the ax5 bolted to it.. so if i use the block as a long block with my intake and exhaust why wouldnt it work? can any one ive me an answer? has any one done this swap before?
my engine is getting noisy with 200k on it so i found a low mileage 70k yj donor.
 
You can use the block it is the same.

But yes you will have to swap over everything else.
 
thats all i needed to know, thanks. it looked the same to me and that was my plan but i didnt want to have it apart before i found out.
 
I did a swap from a 94 yj to a 2000 tj and everything swaped over good. Just used all my brackets and manifold from my tj. I did have to have the exhaust re-routed due to the oil pan being a lil diffrent.
