Posting this for my brother. The car has been modified to surpass the performance of stock STi spec. He currently has the 06/07 sedan front end on the car but can switch back to the wagon parts if needed. Below is taken from his post on VIC@NASIOC.
Considering going back to school full-time so might need to sell the little wagon... I spent the last 4 years slowly building it up and it is sad that I might not be able to keep it.
