    5.3l

    Contemplating doing a 5.3L swap in my Jeep now... I have available full truck with engine etc..

    What else will I need to do this? Can I keep my power train and be able to just put the 5.3 in without changing DS and such? I know I'll need some sort adapted for tcase and engine but don't know anything else really.

    Anyway and all help or directions would be fantastic... Even a parts list... Cheers

    His went into a yj, but there will be nothing that doesn't require some type of modification of some sort right to the yoke on the diffs, btw what diffs? You put a 5.3 on a 30....... Well good luck! Lol

    Was told Dana 30/44 combo would be ok... Also planning on using my trans and tcase also hoping to keep em in same locations which allow me to us my drive shafts..... And just get an adapter for trans to engine..

    44 would be ok but I wouldn't trust a 30, maybe another 44 or minimum HP30

    This type of installation will require modification to the driveline. you may be able to keep it close to the current location but I doubt that it would be exact.

    why keep the current 5 speed. if youre going to go through the work switch the gearbox out and go auto. You'll be much happier if you off road it.

    As for the D30/44 combo. You can make the D30 survive but you would have to learn to go easy on that skinny pedal. However, I would tend to think that Thing is correct on the minimum requirement would be a HP30 but again you would still need to learn how to be easy on that skinny pedal.

    There are lots of misc costs to consider also.

    Exhaust
    Cooling
    Fuel lines ,pump
    Guages

    I get confused once numbers get bigger than I can count on my appendages. I'm only good up to 21!
    one quarter turn before something breaks is a good torque spec.

    IMHO one of the best upgrades to a jeep is the addition of V8 Power and torque. like everyone is saying its not a task that can be easily done, but if you have the skills and the willingness I wouldn't hesitate to tear the 4.0L out and put in the 5.3L. You'll likely get better fuel economy and the performance will leave you thinking why didn't I do this before now.
