thanks for your answers. i see what your saying. basically if i get a 99 or 00rs than i can just drop a newer sti drivetrain in w/out having to pretty much rebuild the entire car due to the awd setup that already is in the newer rs.

how are these boxer engines w/ boost? how much psi can they take w/ outneeding to be built? given all of the diff drive trains available what swap would be the best bang for the buck?
