If you get a NA car, then adding Turbo can run you around $3k (depends on car and kit) if you do labor yourself. It's not always worth it to do so since it will shorten life of your engine (because NA engine parts aren't designed to take high pressure that Turbo will be producing) and might not give you that big of a HP gain.
It all depends on what you want to do with a car I guess and your driving style. I would suggest simply getting something like older WRX or any other "already turbo charged" cars. If you are getting NA car without much of a choice, then save up for another car and have 1 for "day to day" driving and other strictly for racing (heck, some cars after "all set and done" aren't street legal or "cop magnets" anyway

)
Good points but, you also got to consider the compression ratio of the engines them selves. Trying to put a turbo system on something that is highly strung like a Honda S2000 (11:1) is almost suicidal. Personally speaking I wouldn't use an older car to start off from for a turbo experence. Many of the older turbo system prolly won't hold up to the test of time or have some what "crappy" equipment like ceramic turbines.

That hissing sound you hear when they hit the clutch to change gears is actually the waste gate. When the turbo is running and fully spooled up there is about 18-25 psi of cold air pressure, depending on what the engine can handle. When you push in the clutch you usually take your foot off the accelerator. When this happens you have a lot of air going in to the cylinder and not much fuel, a lean mixture, this may cause the engine to stall. The other problem is that if you don't send to air to the cylinder because you don't want the engine to stall you leave it in the turbo system, which is designed to withstand only so much pressure, and ending up damaging your turbo. The waste gate cuts in when you push to clutch and bleeds the pressure so that you don't damage the turbo or stall the engine.
I think you got your Blow off valve and wastegate mixed up. The wastegate controls boost and the blow off valve is what vents the gas when you drop the clutch/lift off throttle. Also 18-25 psi? Most cars don't have anywhere that much boost stock, a WRX STi only pumps out around ~14psi and thats considered high. 18 ~ 25 thats like 1.5 / 2+ bar of boost.

Yep rotary engines are hard to maintain and they require massive maintenance...
And basically, almost all the cars driven in the anime has a turbo in there... like the R32 (Skyline) it has 380HP in stock mode usually R32 comes only at 276HP (280HP)
and as for the FC it was detuned to 250 but before it used to be like Keisuke in the 350HP range...
Thats got to be one of the greatest myths ever, even in theory a rotary should have better reliability, I mean there is only 5 moving parts in a rotary compared to +200 in your standard piston engine. Rotay are every bit as reliable as pistons, the only reason why they cost so much to maintain is becaise there only one company making rotary engines. A stock RX-7 with a 12B or 13B will happy do +120,000Km before a rebuild.
And yes, I love rotary. Anyone seen that Jap vid of a 600HP 20B inside a AE86 will know why
