i didn't know you can keep it auto with a 3sgte
You can't(simple answer).
The 3sgte never came with an automatic except in the Caldina but that auto was only for awd and is expensive. And the 3sgte would end up killing the automatic in the Camry guaranteed. I have seen an Auto 3sgte Camry with full engine management before but I don't even know if the guy ever got his car to work right. Basically, don't bother. It would be easier to either do a 5 speed swap or put in a 3sge(since you could get that with an auto in japan) and turbo that. However, the 3sge is not built to be turboed like the 3sgte and the high compression does not help things at all.
If I were you I would switch to a 5 speed setup. Actually, I think a custom turbo setup on your V6 would be cheaper than a 3sgte swap with 5 speed conversion or making a 3sgte work with an automatic transmission. Just be warned. You may have faith in your auto but it is still gonna break with any significant amount of power (200+whp) put on it.
