I say get a 04 that way you get your LSD and stg 1 injectors and also they are less likey to throw CEL's from overboost. My stock turbo bolt on 05 dynoed 291whp/360wtq and would trap 111/112mph all day with bad traction in 2nd gear. FWD FTMFL!!!!! But now my big turbo car traps 120mph all day long. Just be careful while looking for a "used" one since that means problems imo. I got mine new with 3 miles on it and NEVER have had one problem with it (knocks on wood) lol
