Correct the RC's will fit with the 99 manifold. Though as said, you will have to cut the ends off the stock injectors wire plugs and put on some of RC engineerings injector plugs. No big deal...

Also the bracket is not quite long enough but with some washers or copper piping (cut) they will fit snug.

Though another suggestion would be to get 420 WRX injectors from poeple that are upgrading. They can be had for about 150. They are shorter, but should also work with the 99 manifold.

Oh yeah the Turbo is the T3 turbo, and for sure the effiency of the turbo definitely starts dropping around 10 PSI, though you can still make more.

A great turbo for the setup, since it spools up so damn fast.
