No real gains to be had, the intake on those cars flows way more than the cam will ever allow.  I recommend going to a higher flow cam for probably the best power gains in a NA 4kq.  Also, consider swapping in a 2.3 NG/NF bottom end.

Of course, as others have mentioned, turbo conversion is the way to go.

Exhaust will pick you up about 5hp in the top end, especially with a good cam.
