Stock Horsepower Ratings

[91DX Sedan]

My ride is sporting 92hp right off the showroom floor.
What kind of increase can i expect with a full exhaust swap w/header?
Intake has been modified as well and of course the MPFI conversion. is there a cam I can put in the D15B2 to kick it up a notch?

2nd question: Bosch platinum 4's, and how the heck do they increase horsepower?

I had bought a set of platinum4s a while ago and havent been very impressed! They really arent that special. I reccomend NGKs. Spend some cash and get some cold ones from the get go as well, in case your gonna run boost or nos.
