2.5RS Nos
I really really really wanna put nos in my car... I checked nos's website but they only list specific apps for wrx and the 2.0L. Does anyone make a kit for the 2.5 or do you need to go with a generic kit... if anybody has any nitrious kit in their RS please let me know and how you feel about it... especially if you have added an after market turbo cause that's what i'm planning on doing. I would REALLY apperciate any info someone can give me

AFAIK there are no ready-made nitrous kits for the Impreza. You have to adapt their 'generic' kit to the car. As it is, nitrous + turbo on an EJ25 is not a wise course of action. You can make all the power you want with just the turbo kit.

HONDA KILLER!
Don't do it if you already have a turbo. If not, go check out rallitek.com on the performance link of the impreza page like the third product down called Stage 3 N/A kit will make your car a beast!!! It's like a 2 grand kit but you get EVERYTHING- clutch, lightweight flywheel and nitrous kit (not by NOS) it mixes fuel and nitrous before combustion so its a much safer, more reliable nitrous mod than NOS.

NOS IS GOOD
Seriously guys, do you even know how nitrous works, also did you know that if done right nitrous IS NOT BAD FOR YOUR CAR. You just cant become Mr. Big ***** with nos and think you can squeeze a 100 shot of nitrous into a little 4 banger without some serious mods. Most definetly you can get away with a 50 shot of juice in your car with almost nooooo problems.
Nitrous works on almost the same priciple as a turbo does. What nitrous does is it adds colder denser air into the engine and when in passes through the MAF it tells the fuel injectors to put more fuel into the engine, thus creating a large explosion and more hp at the push of a button.
That was just a quick little explination for how nitrous really works.

Before you come back with more technical information, please do not use the screen name "spaz." Nitrous does not get read by a MAF- it is a speed/density system which reads the velocity of the air flowing through it and uses an equation to determine the weight of the air passing through per minute. If you add a dry kit to your car, it suddenly runs much leaner, which does make more power, but puts MUCH more stress on your engine. If you use a wet kit, meaning one that introduces the proper amount of fuel for the amount of nitrous being injected, the engine never sees overly rich conditions.
Why is this an important distinction in an Impreza? Because nobody makes a specific wet kit for the Impreza. That means you are running their generic dry kit if you don't have decent engine management that can recognize when you are using it and adds fuel accordingly.
It works nothing at all like a turbo. The only information that was correct in your post was the statement that you can't go nuts with it. That is entirely true.

Im running a 30 dry shot of nitrous in my car, and there were no ill-effects. My next plan is a wet 50-60 shot. Now that I got my new clutch (Stock one from the TSB, but it holds alot more torque than my origional one).
I built my kit from scratch, and it worked fine for the one bottle I pushed through it. Personally, I would do it again.
As for with MAF cars how it works...if you put the nozzle before the MAF, it will cool down the wires inside, and will think the intake is LOTS and LOTS cooler than it really is (this can be good or bad, depending on how the ECU is set up to react to such cold temps) It could either run equally rich (like stock) or it could run overly rich or even blow the MAF. If you put it afterwards, you will be pushing more "air" through the engine than the MAF thinks you are and can possibly run lean.
