i would look into the python injection venom vcn-1000. Computer controlled dry kit that hooks up the the TPS, o2 sensor, and fuel injectors. It adds fuel as necessary from the injectors and monitors the lean/rich condition via the o2 sensor. Pretty nifty. Safety and power profile of a wet kit, without the issues of regular dry kits. Mine will be sporting one shortly, as soon as NA 14s are reached (hopefully the 14s will be here saturday).
Dry kits lean out the mix way too far and burn pistons. Period. The stock manifold has very long runners with many twists and turns that are only intended to pass dry air, so a single nozzle in the intake tube or throttle body will not get even mix to all cylinders. My advise is leave the nitrous in the dentist office it is much safer there but if you must; step up for a multi port system that mounts under or near each injector. More work and money up front but your pistons will probably live if you do not get carried away.
