if your trying to make it faster by bolt-on's on the stock motor then you are waisting your time. you wont ever notice a difference from I/H/E. your best bet is to do a motor swap or build the stock motor for a little turbo setup. if i had the option of swaping in a B-series motor with a turbo kit or just swaping in a K-motor N/A. I would deff. choose the K motor route. The first thing you should do is make a resonable budget.
