I'm looking for a rough HP number that the stock engine/components can handle safely... I'm running a cai, chip, and exhaust, aswell as upgraded plugs, ect.. minor stuff. I am planning on getting a wet nitrous setup pretty soon for a little cost-effective get-up and go when I want it. The system I would be getting would be between 100-120 shot, which is a decent amount, esp on a 150,000 km engine, though most of the kilometers (a good 70%) have been highway milage, as I travel alot.

I'm not looking for a specific magic number, a rough guestimate would be great.
