What are your power goals? What class or speed do you intend to run in? You need to find your power goals before you build a combo that will or won't fit your needs.

No matter what the answer- I would reccomend that you invest in a ball bearing turbo like a GT series. In your case, a GT67 would deliver lots of air right in the peak efficiency zone... which will produce minimal heating of the air. Unless you are bound and determined to avoid the use of an intercooler- I'd suggest you consider it.
