hey guys and gals i have a buddy on TPE that is selling a gently used turbo and i am really interested in it. but 1st i would like to know what PSI i can push on a stock motor. I am planing on putting LT's on but should i wait if i get a turbo? I drive my 99 T/A everyday and i was just wondering what all and what it would cost to turbo this baby. the turbo he wants to sell is a T04S 60-1 Stage3 Garrett ( journal bearing ) The unit is a T3/4bolt 2.5 discharge .63 AR. that's all i know on it.
