but you dont want the 4th gen 3sgte, the turbo and exhaust many is all 1 piece and the prices for the caldina clip is just out right expensive! ebay has had a few for $5k, not worth since most of the after market is made for the 2nd and 3rd gen. Hell there is more you can do with the 1st gen than you can with the 4th gen since you can slap all the 2nd gen stuff on the 1st gen and do all the 2nd gen upgrades.

1st, 2nd and 3rd and generaly all alike and are backwards compaitble, all the 2nd gen stuff can go on the 1st gen and all the 3rd gen stuff can go on the 2nd gen.
