I heard that the sr20 runs pretty rich esspecially under ful throttle if this is the case would it be alright to run a small system like the sneeky pete sytem dry. I don't want a big boost just alitlle but don't want to ruin my motor

If you tune your car good for nitrous and don't go overboard on the shit you will be fine. I do not reccomend the sneaky pete system because it is small and it will run out very quick. It will piss you off when it runs out. If you are going to go the nitrous route get a big kit. Either it be ZEX or the NOS brand.

If you have the money go the JWT route with nitrous but keep in mind there are ways to avoid the JWT setup when dealing with Nitrous.:D
