Ok, I've tried the search feature, didn't see any info on replacing my 2.3L, and not sure if it should be in this area or the engine area----- I've got a dead 2003 Ranger and looking for fastest cheapest way to put it back on the road. It's a 2.3L/auto trans with a supposedly bad head, but at 200K miles I don't want to put the work/money in the head and have limited or end of life engine. What are my options to replace or upgrade the engine on the cheap? I've searched E-bay, there seems to be alot of 2.3's for sale for '04 and later model trucks---can I use an '04-up engine as long as I get the harness and computer with it? What about the 2.5, I've read those are stroked 2.3's and are the same block, simple bolt in replacement? Any other simple engine swaps (6 cylinder Rangers) that I can still use my same transmission with? Any info, help and even PM's with a running 2.3 sitting in your garage will be appreciated. I'm in the Florida panhandle and willing to drive a little to get a good engine. Thanks!
