Yes, you can swap out the '90 four cylinder for a 4.0L from a '95. No, it's not a simple one for one swap. Reading up on the numerous swap threads in the Wrangler section will give you a good idea of all that is involved, such as moving engine mounts, upgrading the transmission, and getting the electrical harnesses incorporated.
