You still increase intake charge temperatures with .5 bar.
I guess what I'm saying is heat kills engines. I would use an intercooler even at low boost levels. But that's just me. I've had friends kill their engines with low boost and no intercooler. Not to mention the car will be quite a bit more temperamental on hotter days and you can run the risk of engine knock. In the summer time CO gets temps above 100 degrees Fahrenheit and many, many days in the 90s (i'm from Denver BTW). your choice. I know what I would risk on my motor.
There is a difference between cheap and inexpensive. Throwing a j-pipe on a non-turbo motor seems cheap to me and I wouldn't do it to my motor. I wouldn't even do it to a friends motor. That's just me. Granted porsche did have 3.0l motors with NO intercooler and twin turbochargers and they got WAY over 300 hp out of them but that was on a motor designed for turbo charging and these were on race prepped cars, etc. I'm sure others have done it too, but probably not cheaply.
The one way to find out how smart it is would be to see how many people have done it and how many motors lasted the test of time.
Staging? The exhaust on turbos work with the intake. You replace the exhaust you need to replace the intake, etc. etc...
EDIT: you could probably buy the intake first then exhaust on turbo. I guess it depends on what turbo system you go with. Stock porsche systems you need the intake and exhaust to work, but I imagine a home made system you could stage by making the intake work without the exhaust and turbo. There are still other issues with turbo charging a non-turbo motor without opening it up and changing the cam timing, etc. And you can always buy parts and not throw them on, but that's annoying.
