Probably just a basic street port, but I'm not an expert on that. I did port my TII's motor myself, but I just did a street port and I have made other modifications.

If you still have a catalytic converter you'll probably want to keep the air pump, removing it can shorten your cat's life. If it were me, I'd pull the cat and the pump, and the EGR... and so on. Which is what I did to mine.

Why you wanna port?
Are you doing it cause you need to rebuild?

What else mods do you have?
If you're running a stock exhaust, it's almost a waste of time.

So he can't put a different exhaust on later, when he might have more money? In the short term it might be a waste of time.
