yeah everybody here is turbo all the way :-)
anyway, I think nitrous is a very good way to go, especially if you like to go to the drag strip and show the hondus and cameros a thing or two.
I just don't have experience on the kits, I was looking into pieceing one together for my car.  I was just going to start with the sniper kit since it's cheap
I think they are all pretty much the same, so whatevers cheapest.  
However, as far as what the stock internal engine can handle, well I am making about 90hp more then stock with the turbo, so you should be able to do about the same with nitrous.
Figure on the 75-80 shot or something
have fun
