Hey, I have a n 88 yj. It has the 2.5L but only has 16k total miles. I am looking for a little more power. I have looked into a small block V8 swap, but that is involving more than I think I'd like to do at this point and cost. Is there a simple drop in motor option (v6?, 4.0L) for this YJ, or is it a big undertaking whichever direction I go? This car does have a sentimental value to me so selling is not an option, and I do want to keep this for a very long time.
