    Engine-supercharge or LS swap and why

    So I keep debating swapping Out my motor which has just under 130k miles with either a reman and super charger or dropping in a LS. Seems many that do the SC eventually yank whole thing and drop a new motor. Is there a reason? Do those with SC see other issues? One reason I am leaning SC is because of how easy we can work on the 3.8. Once you drop a LS or Hemi there is virtually no room to work on the darn motor. Not looking for the typical go big or go home junk lol. Overall I love my JK and just want to keep it on the road and trails. It is my DD also.
    Thanks.

    It's your daily driver and you want to keep it on the road ? High Performance and low maintenance don't go together. Maybe you need to just regear and save your money for something that hauls ass.

    LS all the way...a SC is nothing but problems getting them setup correctly. That and the V^ was never designed for the added HP.

    So I recently rented a 2017 Tahoe for a cross country trip and have to say that I really like the 5.3. Now I just have to decide if I wasn’t to do the swap myself or not. I may have to pick up a beater just to make sure I have transportation when doing the swap in my garage. Never dull.

    I was just reading a post from Motech. He had mentioned that the power increase from the 3.8 to the 5.3 wasn't really that significant, so he would recommend moving up to a larger LS. They really have it figured out from everything that I've read. From the different Gen's to tranny's...it seems they are king when it comes to the LS conversion. The LS doesn't take up near as much space as the HEMI does either.
