Wear seems normal for a 30 year old 4 cylinder. I use nothing but the cheapest oil and filters. Most turbo 4's do not survive this long for various reasons but this one was going strong until the head gasket let loose. Head gaskets are a know problem on this engine. They always fail in the same place by #1 cylinder. #1 was the only one with water on the plug. She will be running fine soon.
"Most turbo 4's" aren't the Chrysler 2.2. It used the same rod and main bearing diameters as the 440/426 big block, and was designed by the same engineer responsible for the slant-6. It was one stout bugger, apart from the head gasket. Even that usually lasts a long time unless you start dialing up the boost.
I never personally got into the whole FWD/turbo thing at all, but I knew some guys who had a lot of fun with the couple of years where the turbo engine was offered in the Caravan and Voyager, turning up the boost to "insane" (later by reprogramming, earlier by just putting a bleeder valve in the boost sense line or fiddling with the wastegate spring and an extra fuel injector in the intake) and then running in the 10-12 second range in the 1/4 mile with them. O-ringing the block and using a Powerstroke intercooler were the major tricks, they usually left the bottom-end completely stock and rarely had issues. Plus they could putt along the freeway at legal speeds and get 25-30 mpg if they wanted.
