Default Boosting Infiniti VH45 with single or duals

Hello all, I am looking for some help choosing between single or duals for my build. It's for a VH45 4.5L, 4-valve V8. The guy tuning my ECU says 8-10 psi is all the stock injectors and MAF will handle so I want to stay there for now.

I can pick up some 300zx T25's used for cheap and was wondering how they would perform at 7-10psi and 7200rpm redline?

Other guys that have turbo'd the VH have chosen expensive BB twin turbos or big singles like Holset HX35s and T70's. I am a shadetree and don't have much loot.

So I am looking at those and am a newb and can't read compressor maps, they give me a headache. Any input would be appreciated. I was also thinking about T25/T28 hybrid but that's adding more cost, which I could use for one bigger single.

Let me know if you need more details about the engine or anything. Just need someone experienced to help me out a bit. Thanks
