R32 _ULTIMATE_WEAPON

I was going to go the -10 400HP. Are these the best kind of turbo's or is their some thing better for around the same cost? also I take it has a steel wheel anyone know?

Garrett GT2560R GTR ball bearing turbo HAS ANYONE USED THESE TURBOS SPIC'S These GT2560R units are a true bolt on replacement for the Nissan GTR and make for a great bolt on upgrade with similatiries to the GT2530. Dual ball bearing operation makes these a super responsive unit rated at 320Hp efficiently with scope for more power. Price is per unit $1485 -7 320HP -5 350HP -10 400HP Has anyone got anything to say about these turbos good or bad?
