If that's the original color, I think it is fairly "rare". 400hp for a single swap with forged internals, etc.? Seems like a waste to me. I'd up the ante to 600hp. If 400 is your true goal, I'd take off all the single turbo stuff, sell it, get some TT tubular headers and upgraded TT turbos. If everything is too far gone to do that (kinda sounds like it), then a T70 size turbo it WAY overkill for 400hp. Using that turbo for that power goal I'm betting is going to be pretty disappointing to drive.
