HKS GT2530 on a S13 SR20 @ 17 psi

Symptoms:
1. Makes a grinding like sound from the turbo when I hit full throttle
2. Does not build boost but I didn't keep my foot on the gas for too long either
3. Blue smoke came from around the turbine and turbo elbow area, once that I noticed
4. After hitting full throttle for about a second and the rpms drop back down, the turbo would make a grinding noise for about a second
5. Rattling noise coming from the turbo during idle and normal driving

Things I've already checked:
1. Turbo is not loose from the manifold or elbow
2. All hoses are secure and tighten
3. Shaft play about 1 to 2 mm
4. Turbo spins freely

Anything else I should check? So do you guys think the turbo's done? I need to be sure before I go out and get a new one.
