if ya dead set on a turbo'd glxi then ul need manifold, inj, fuel pump, turb, plumbing, a computer, new front pipe probly full exhaust, then brakes, probly look at the driveline so you can actually use the power, possibly could use a gsr head an bolt it to the n/a blockwith a couple of h/g's to drop the comp abit, really is a big waste of money if ya havin to source everything
come to think of it didnt he just buy a gsr...
