Honestly, even with #2 I'd have second thoughts. One big turbo should more than do the job to deliver enough PSI to get over 1000hp. If I was planning on playing it safe around 500hp no way would I spring for the twin setup. It's just a waste of money.

The guy I recommended you talk to on facebook is a young guy, long time Z fan. He's just building a business so he can't afford to specialize in Z's or tuning, or anything else. He's an all around body/performance/mechanic shop. Quite honestly, I don't think the demand is there in our area to support a specialized shop well. He know's his stuff though. I trust him because I talk to him all the time. We are constantly in each others garages lending a hand on each others projects. I'm confident he knows his turbo's because I've seen and driven his custom made system on his Lexus. He literally bought all the components, bent the pipes and built his own kit. My only point here is, there are guys here that can do the job you want. You may have to open your mindset away from the hype of twin turbo systems or the popular shops and find a guy in an unconventional place to get it done. Or bite the bullet and ship it out for the cool factor and piece of mind of more reputable place and build. Either way your car will be sick! just something to think about!

Sure you can build a single turbo 1000 whp monster, but it will only be useable at the track and there will be very little power in a daily situation. Twins help resolve that with quicker spooling/smaller turbos while maintaining power levels. A popular mod for TT supra was to convert them to single big turbos. This made huge power at the top of the range by sacrificing low rev range power. Great for 1/4 mile and highway racings, not so great elsewhere.

Here's my logic:
If you want cost effective turbo kit and plan to be around 450-525 whp, get a single turbo.
If you want room to build the motor eventually/ get 600+ whp, then plan on investing in a decent twin setup.
