Ok how much psi can you put on an auto tranny the auto tranny is built better than manual granted the manual has an extra gear but the auto trany is supposdly bulit better so shouldnt the auto be able to support better turbo than stage 0? The wrx 4 speed auto is able to support up to 350hp and around 360lbs of tq with 14 pounds of boost? So shouldnt the auto be able to take a better turbo IE stage 2 scionspeed 290whp or even the stage 3 ??? How much of a differnce could there be between the 2 trannys?

high stall torque converter could fix that

but then you must worry about the differential (quaife anyone?) and bending the axles

I have an auto, and I wouldn't go any higher than ZPI stage 0 with a stock car.

besides ZPI who else is making a turbo kit for auto tC's?

I think just scionspeed. For some reason though, my intuition is telling me to go with ZPI. It might just be the fact that its the company that oldman is going with, but either way, I'm going to let the kits stay out for a little while so all their flaws come out of the woodworks before I stick one on my car.

turbonetics and greddy have one in test i think hks has one out dont quote me on that but for sale is just zip and scionspeed but just was wondering has anyone tested a higher stage turbo on an auto?

If you're not going for ZPI, go for Scionspeed. It'll cost less than HKS and GReddy and be the same thing. I think..
