hey, I´m originally from the states and am big on american muscle and keeping things for the most part stock. My original plan for first gen legacy was to drop a chevy 4.3 and turn it into a rear wheel drive but my ideas have changed especially after moving to where there is a lot of snow and ice and found AWD to be all important. I am making plans to keep the 1800 just for money reasons even though I can get a 2200. I have plans for custom exhaust and intake and looking all over the net for any help on anything else I can do to get the hp up. I have access to a small machine shop so...

I´m an auto body guy so I need help with engine stuff. I know enough that I pulled the EJ18 out gave it a good over. Its a good engine but I want to pull as many ponies from it as I can. I was wondering if its feasible to keep the EJ18 or if I should swap an EJ22 and pull ponies from that. I know that its kind of odd to make a station wagon "cool" but its something I have always wanted its getting painted candy apple red custom made body kit by me cowl induction hood made by me. I´m going to remove all emblems have the Subaru crest in gold pearl on the hood ghost effect and STi ghost emblem on tail gate. I will be posting pics when I start. I don´t want to start the body until I know exactly what I will be getting with the engine. Any engine help with the EJ18 or ideas what I should do engine wise. I have already ordered several STi parts to add onto my car. but am still looking for STi rims that I saw on a forrester in japan. Edit: I want to keep it an all wheel drive with high/low. I live in Iceland and will use this car a lot during snow and traveling in the country. it will be lowered but will be able to raise it back up and put something other than street tires under it.
