first off, no, i don't own a 1uz powered vehicle, but damn, i do want one, and i'm researching my ass off to find the right things to do once i get it
this is kind of a loaded question. because everybody is going to be different, wanting different things out of their car. but he did lay forth some requirements at the beginning. 2k budget for BOTH turbos (meaning under a grand a piece) 12-14 psi boost, stock motor and great low end response. off the get go, 3 turbos come to mind (i'm kinda partial to garrett, so i'll be using them as examples) a gt25r, a gt28r and a gt28rs. the 28rs is soooooo ideally matched to the flow requirements of this engine at that boost its scary. from a power and reliability stand point, 2 of these guys would be perfect, even up to about 18 psi, they are still in their peak efficiency on their flow maps. however, these turbos are about 1300 a piece new. the other two are obviously not going to match the engine as well, but they are both under the 1 grand mark. it all comes down to what your peak power wants are. the gt25r's are worth about 240 and the gt28r's are worth about 290 a piece with a bit more lag than a 25, but probably a negligable amount. both are ball bearing, and use technology thats about 15-20 years ahead of a standard t3/t4 turboso either would be a great choice. if i had to choose between the 2 of them i'd go with a 28. thats just me
