Lol...Iv been through 4 sets of turbos, a blown motor, and various other horrible problems. They screwed me out of so much money, 2 years later my poor z32 is still sitting in the garage... Ill never go there again. They can't do anything right because their owner is a dirt bag. Doug will try to maximize his profit by telling you he is putting quality parts on when he really would just order cheap crap off ebay. If you go to Zfever you are taking a huge gamble. Id rather just give my business to turbotoys or something. Or just learn how to work on it yourself like I had to.
