So i have a 2000 GT with the 4.6 (obviously) anyway i was looking at getting an svt engine to throw in there instead but after a quick look around the internet have decided that that option is way to expensive.

So what i want to do now is just start tuning my engine. but what i want to know is how much can that engine take before internal parts start breaking?

i want to supercharge it, better fuel pump and injectors, maybe a better cam, and a cold air intake.

of course if anyone has an svt engine they wanna give me i'll take that too.
