[QUOTE="Speartip, post: 452080, member: 23341"] I've researched many diff topics & mods for my Jeep. TBH I haven't come across anything written about putting a 4 Litre in a JK. I do understand many Jeepers cherish the older 4 Litre . There are some knowledgeable people on this board so if it's been done I'm sure someone will chime in . I do honestly think it would be a lot easier to just replace the 3.8 with another 3.8 crate engine . Good to go . As the 3.8 is a bit underpowered compared to the newer 3.6 . The 3.8 can be very reliable & last a very long time . [/QUOTE]
