very clean, but the turbos are more expensive than that, i got mine used but upgraded, theres a guy in zhills that rebuilds for 500 and upgrades for 750, theres some kits on ebay but the cheaper ones wont last, and the really nice ones are over a grand

gen2 have ct26 1991-95
gen3 have ct20b 1996-99

im pretty sure thats correct, theres also kits to get other turbos in it
