If I remember right, the N/A and turbo use the same Auto tranny, just different clutch packs are in it. The manuals were the ones that were different.
As for the turbo in the N/A car, I hope he did a correct conversion, ECU and all, check on that too. Here's a link of what should've been done... MAN I'm linking this alot lately...
