Ive been working on this buggy on and off for just over a year now.  Its nowhere near done, and wont be anytime soon.  It started as a 4 door 2000 2.5RS Impreza, and mechanically still is (dont let the 02 tails fool ya.. I just like them).  Other than a slightly tweaked engine from the previous owner (bored, decked, 3-angle valve, port & polish, high compression pistons  ).  Ive also modified some stock 04 forester struts w/ 300lb front & 175lb rear 2.5" coilover springs. 
  
Current cost is just over $2k.  Just passed emissions 2 days ago.
