bought mine with 35k on it, boosted 8lbs with a turbonetics T3T4, SafcII, and vortech sfmu from 67k when the warranty ended till 115,792. Didn't have probs till 108k when headgaskets started goin left and right. First one went in boost and burned the deck so bad that not even tack spray could make up for it. Third time around I bought eagle rods and It's been a table in the corner of the shop for the last nine months.
