I know this is old, but thought I would add my $.02. If you are going non-intercooled and want to keep it simple, why not mount the turbo back where the stock muffler is ala STS. They seem to have good luck with the rear mount turbo. Everybody seems to think it would be laggy from all the piping but I have talked to 3 different guys running this exact setup and lag is not an issue. Not to mention the packaging benefits. You also get *some* cooling from the boosted air running through the long charge pipe to the engine. As far as turbo selection goes, a 60-1 probably wouldn't be ideal given the low boost pressure you would be running. I would look more into the Mitsu. 17c or 19c wheels. That's what the Syclone/Typhoon guys run. It's more geared for larger displacement engines running low boost.
And here is STS for those that have not heard of them: http://www.ststurbo.com/
