There is a little misinformation here.

1. The injection methood depends on the intake, and Chrysler has stopped using carbs in their 4 cylinder cars a long time. It had been replaced by throttle body injection. A cheap way to make fuel injection with a carb designed intake. By 1989 both the 2.2L and the 2.5L were using the same port injection.

2. In 1989 Chrysler switched to the common block which means that the 2.2L and 2.5L use the same exact block. They bolt into the same mounts and have the same bell housing mount so they will bolt to whatever transmission you have in your car. The difference is that the 2.5L has a longer stroke than the 2.2L provided by a cast crank while the 2.2L, only used in the Turbo II and Turbo IV cars that year had a forged crank. The 2.5L was used for all Turbo I and non turbo cars. The 2.5L also has balancing shafts to reduce vibration, the 2.2L does not. The balance shafts can rob up to 10HP. Other than that, they are identical.

3. You might gain power, and you might lose it. If you're going to put in a 2.2L, I suggest you convert to a Turbo II. The 2.5L can give you a torque advantage, but it's really about preference. I love my Turbo II. I'd also suggest swapping in an A-555 or an A-568 as they are the stronger transmissions from Chrysler.

4. The 2.6L was a Mitsubishi engine not noted for being very good and will not swap in easily, in case anyone is interested.

Chilton shows 2.2, 2.5, and 2.6 motors for that year Shadow so Im guessing a 2.2 will work but might lack the power you were used to. Best of luck.

It will fit if you change a few things like the transmission and engine mounts and also the 2.2 was carb and the 2.5 was fuel injected. Here are a few cars with the 2.5 liter that is interchangeable. Shadow/ Sundance, Daytona, Dakota, Caravan/Voyager and was available till 1995.
Good luck and hope this helps.
