I run the zex kit with a 55 shot in my B16A2. With a 55 shot youll need new plugs, NOT platinum!!!!11, and youll eventually need a clutch. How many people learned how to drive a stick in your car? My clutch lasted 2 sprays, then slipped all over the place. To run higher than that (55) youll need to get a fuel pressure reg and retard your timing 2-4 degrees (not 10) depending on your individual motor. I would suggest the MSD 6BTM for the timing, you can just retard yourself with a knob in the cabin. DONT engange that switch before you start racing either. Youll floor it in 1st and ruin your engine, Ive seen it happen.
I would also strongly suggest an A/F ratio gauge.
