I would consider nitrous if I had the $$$ to put in a new engine if it shortens the engine's life.

It seems it would be difficult for any real beneficial mods. I don't think supercharging is possible due to space and the position of the crank pulley. Same with a turbo, no room. A much larger engine won't fit and would probably snap the drive shaft.

The one I saw that was going to 450hp was a $40K job so I'm guessing it was done right, but that's a chunk for something you're not racing it.
