Ok, I am kinda new to using nitrous. But here is the set up I am planning on. Either purchasing another stuck manifold or purchase the one from importshark. Tap the runners for a direct port setup. If I do this, what type of "shot" could I safely run on stock internals? I am planning on upgrading fuel pump, and injectors as well. I already have a BBTB and intake. Also a few other things, that are not related to this setup.

 

You don't need injectors. The only things you need other than the kit are the Walbro, a standalone FPR to control it, and the right spark plugs for the shot you are running.

You can run an 80 shot with this, but I would recommend getting a controller for anything higher for traction/shock issues. After that you should be able to run around a 100 shot safely.
