Needs some pics of the finished product, Sammy.
I agree with the others, the Konis have much more damping than the stock struts, though on the low settings the feel should be very similar. They seem to be quite deceiving in their damping as they seem to make the car ride smoother than the spring rates would indicate which is one reason people love them for their daily driver.
Once you have broken the Konis in and turn the damping up, things should feel much harder, but the Konis at the higher settings are probably too much damping for the the SPT pinks you're on.
If you are looking to get the wagon to feel more like the MR2, it sounds like you'll definitely want to up the spring rates considerably. Since you're running the RCE plates, you can get away with running sedan springs, so your options are wide open. JDM pinks or perhaps RCE's STi springs might be more of what you're looking for, but I'd wait until you get it aligned and put more miles on the setup.
