what car are you going to be running it in?
what engine? power figures etc.
i run an s series behind a 20v and it holds up just fine, a t series should never beak behind a stock 4a, anything more than that and you MAY have problems with axles but really it all depends on your driving style
id probably save myself some $$ and just get a t series for around $400 and just weld it (personal preference) and keep it mind a welded diff is illegal on the street
