Resurrecting thread for a final report
In late March, I set off a firestorm when I asked about the difficulty of replacing a ’94 2.3 with a ’97 3.0. Most seemed to think it was a crazy swap, better to rebuild the 2.3 or go to a 4.0 or 302. Others thought the change from OBDI to OBDII would be a mess to do. I am sure that your advice was well intended, but it took Rusty ol Ranger to recognize and comment multiple times that I hadn’t asked for advice about whether to do it or not because I hadn’t. Sometimes circumstances dictate that you take a direction that you wouldn’t ordinarily go. So, here are the circumstances that led to the swap.
A loyal member of this family has been our ’94 extended cab with 2.3 and manual transmission. With 175,000 trouble-free miles, it was showing its age. I’m a 4 cylinder, manual transmission kind of person, and my preference would have been to do a full rebuild on the engine. But, the major factor in this was my wife. She loves the truck, but over the years her arthritis has progressed until she is no longer able to drive a standard shift. So, we had to have an automatic. I didn’t want an auto behind the 2.3, so we started looking to buy another. The ones in our price range needed work. We already had our old faithful that had been well maintained. And about that time I came across a 3.0, auto, with 93000 miles and a known history and decided to make the swap. The 3.0 engine I know (from our Taurus). Yes, not a lot of power, but enough for the automatic trans. The 3.0 is also highly reliable, and I just like cast iron. I also like the OBDII diagnostics on the ’97.
The swap has been done successfully. All chassis wiring is still ’94. Everything else is ’97. The swap was pretty uneventful. The only holdup came with some shifting problems after everything was in. RonD, on another thread, was of help in working through these even though, on this thread, he thought replacing the 2.3 with a 3.0 was like putting soysauce on cornflakes for breakfast (that, actually, doesn’t sound too bad as I like soy sauce)
I want to thank everyone for your comments and help. Even the critical ones were friendly. Maybe I should have explained the circumstances for doing this swap in the original post. But, I believe if I had, the responses wouldn’t have been nearly as interesting.
