It should all fit, however, the tensioner is different. It doesn't matter what tensioner you use, what matters is the mounting bracket for the tensioner. If you have a new bracket lying around, you can mount that to the engine and run a new tensioner, if you don't, you gotta go swap it for the older style tensioner.
Oh, and does anyone know how the extra small idler you get one Phase-II's effects the cambelt, is it needed? Cause my car, being a 98 BG, came with the new style tensioner, but not the small idler... so dunno what's going on there.
