upgrade your secondary injectors to either 1300cc or 1600cc injectors. With the 1600cc (required for high horsepower) you will need a new fuel rail and fuel pressure regulator. You also need to upgrade your fuel pump. Just go to one of the rx7 stores and take your pic depending on how much power you want.

Here's a page I wrote that allows you to play with the numbers. It also has some (hopefully) helpful hints about how to choose numbers for each input:

I won't let go
Damn, I haven't seen that before. Nice. That's a keeper.
I would have to say any fuel system that's to be upgraded would include everything. If you're getting serious enough to really want a solid system then the pump, injectors and every last component in between should be looked at and planned out. What's the point of tearing into your system only to find out that you should have done everything the first time around? (Like me)

I have made good power with my setup, at one point I was trapping ~124 mph on the street on pump gas, and have never had any problems at all with my fuel system.
