Are you street riding or just using it for the track?, if you plan on street riding, IMO , in the long run you are better off with water injection, its more expensive, but still less expensive than an intercooler, nitrous is great, but having to fill it is a pain in the ass, and its expensive.
With water meth you can spend 2 or 3 bucks on windshield wiper fluid, and don't have to go to a speed shop, have the bottle up to date etc....
I have used nitrous on both turbo cars and turbo bikes. It works fine and with being a small shot lasts for quite awhile really depending on the bottle size. For example, a 15hp shot will feel more like a 30hp shot.
You would just be safer with a fatter tune if your worried about IAT's. As long as you have a repuable turbo kit, and a good tune you'll be fine. I'm guessing you probably just have a stage 1 and your running what.... 6-8psi? No need to over complicate things.
On a side note I run nitrous on my "mini" ultra street bike. It's a 50ish shot, I only use it to make the turbo kit instantly from a roll...oh and run my air shifter.
