Yup.. 3SGTE only came in the Celica and MR2 (certain years and certain trims). Gen 3 Camrys (92-96) had only two engine options: the I4 2.2L 5SFE or 3.0 V6 IMZ-FE. As far as the block withstanding turbo, it's about your condition and exactly how much boost you plan to run. Meisner's site shows everything he did though. You should shoot him an e-mail as he's really helpful towards any questions you ask him
3SGTE powered Camry kids on TN: Ufoz and theWraith (if I'm not mistaken). 5SFE boosted kids: TheAmazingNate, Mesiner, 5sfte, and... uhh.. who am I missing? RedPhoenix but he blew the engine.. I forgot what happened.. Sucks though
They are all helpful in answering turbo questions BUT I suggest you look at this thread FIRST!

P.S. Sorry if I missed you on the list, I have a bad memory.. BUT yes, I'm jealous of each and every one of you...
