my posession for a couple years so there is no chance of doing that now. I know the auto turbos are smaller so everyone says they fall off at the top end but i didnt feel any power loss but the power did flatten out you could feel where it just wanted to keep building but it ran out of breath around 5500rpm. I think if you are going to try tracking down larger turbos you just spend they money and get some sport 500 or similar turbos. They are only a little more than new factory or rebuilt used stock manual turbos.
If you are drag racing I would for sure stick with an auto trans. But if you are driving on the street and like to shift gears then the manual trans is worth the swap many times over.
