For some reason, there are a lot of them rolling around back home. Just absolutely awesome on fuel. I think there are several variations over the years--I believe there was a 2.3, and a 2.2, as well as turbo and non-turbo versions.
I've owned lots of Rangers, and they're close to my heart--the diesel always caught my interest especially.
I'm pretty damn sure the Ranger diesel uses the same bellhousing as the 2.3 gasser, but I'd double check that.
