I have an 89' YJ Wrangler with 2.5 4 cylinder and 5 speed trans. I have a guy that will sell me an intake manifold, exhaust manifold, exhaust pipe w/ O2 sensor, Distributor w/ new cap, complete wiring harness, etc. plus the computer from a 94 YJ 4 cyl with manual trans. for $300. Is the swap even worth the time and money? Will i notice a difference if response, power, or gas mileage? Is there any other parts I may need or any problems I may run into? Thanks for any and all of your help.
 

It's a decent swap, the MPFI makes more power so it's possible your mileage will improve. Don't forget the CPS in the bellhousing, make sure it'll connect to the newer harness or you can adapt the newer CPS to the bellhousing.
