Engine/Transmission (1994 - 1998) ATS turbo preformance

[MichaelMiller]

Does anyone have any experience with the ATS Aurora 3000 turbo for twelve valves. I put one in a year ago because the bearings were going out in the stock one and have not been as satisfied with it's performance. My truck is a 1996, 5spd manual, 4x4. the the other goodies that I have is Banks twin ram intake, exhaust and big head wastegate on stock turbo. I also have 50 hp injectors, head studs, ATS three piece exhaust manifold, and a fuel plate. I don't know what size it is as it was already installed in the truck along with the Banks items. I am not getting as good of throttle responce and my egts are a little warmer than they were with the stock turbo. I did adjust the star wheel on the P7100 untill there was no spring pressure on the wheel. I would like to get this truck back to the preformance I had with the stock turbo.

IIRC the a3k is a 57/65/15 non-gated? stock turbo was a 56/65/12 gated hx35. You would be MUCH happier with a 62/65/12 or 14 gated S300 IMHO.
