hello,
saw your post, i have been doing some research on the topic. seems that the 3sfe is same in block design as the 3sgte. the motor in the all track. 5th gen i think (j-spec) is a 260hp turbo motor and should bolt in. you will need a stronger trans though. the v6 auto trans should bolt up to it. the 5 speed would be better though.
i am doing the research now because i am looking at making my corolla an alltrac. looking at making the 3sgte swap. i will have to mod one motor mount for my car, but the rest should bolt in(also mod a few axles as well). the parts are pretty much available in japan, just sparse here in the us. the all trac celica, the 1991 body style there were only 81 sold in the us, so picking is slim. i did see one yesterday, the hood scoop is a tell tale sign. but for 81 cars nation wide, to see one herein hawaii is really rare.
anyway hope you can do it. post pics when you do. there are some on swapping the motor into corollas but not to many on camry.
later.....
