Im looking at picking up a subaru wagon. Not sure what I like most, but Im aware a lot of them use the H4. Most likely its going to be between a 97-00. Ill admit im not a subaru guy, and am looking for a quick answer. As far as I know the H4 for this years as just n/a. Is there a huge difference between this year N/A model and a bit newer turbo models? Im asking because this will be my DD, but im addicted to boost and my wife wont let me get a newer turbo verson. So I figure over time Ill just have some fun with it and was curious if parts would swap over and etc. Thanks for the help, if my post made an sense at all.
