My buddy has a built zc in a 91 civic sedan using a td04 turbo ... he pushes about 27 psi on avg .. the thing is fast as hell i can barely walk when i get out of it. Is that turbo a bushing or ball bearing and how long will it be able to ohld boost like that

 

tsk tsk, cmon man i read the turbo projects part of this site before i started posting here, but my guess is going to beeeeeeee well about 1.5 -2 hours (maybe 3 but dont hold a candle to it)
