I'll be running a BNR stage 2 soon and in the car now, I have 550 primaries cleaned by RCengineering and 720 secondaries with a walbro pump. I just want to make sure that is enough fuel.

It's going to depend on the amount of boost you're going to be running on it - rx7.com has a calculator where you can type in the size of your injectors and it will compute your max HP you're good until. As long as you've got a air/fuel meter or wideband o2 ideally, you should be able to see if you're running too lean and not pop the engine, even if you need new injectors in the future.

I'll probably only be running 12-14 LBs of boost with this set-up. I'm not looking to make some monster out of this. Just a respectable 300-350 or so. I appreciate the help bro. Thanks.
