Can someone provide guidance and assistance in determining whether I should rebuild my existing engine block or purchase an aftermarket performance engine block for my 2015 Jeep JK 3.6?

Is it feasible to upgrade the engine block of a 2015 Jeep JK 3.6? If so, does anyone have recommendations on where to purchase a suitable upgraded engine block?

 

the ls swap idea sounds cool, but i'm a bit worried about the complexity. How difficult is it compared to just rebuilding the 3.8L?

 

Yeah, I’m not sure how complicated it is. That’s I’m asking. Can I fit a 3.8? I’m not sure if it’s just plug-in play.

 

I’m just starting to research the same thing. I have a 2013 JKU that except the engine problems it is in good shape. I just got to where I could start adding modifications, and Honey will not part with it. We have had it since it was new and always have had oil consumption issues, O2 sensor problems causing a check engine light. I’ve replaced the computer twice and now the DTC code is related to the variable pressure oil pump.

I can’t swap to anything but the 3.6 due to emission laws.

Looking for something better than stock I don’t need a monster motor.
