Default Nitrous on the 2.5rs

ok after alot of thought and reading just wanted to ask if anyone had luck with nitrous on the 2.5 motor. My list of mods that i have right now are Full K-sport coil over supention fully adj, Veloity stack intake, borla header, Apex I N1 exhaust. And soon to be getting rid of the cats. Then i was doing some research on ECU tuning and i came across I-speed. Theres a local shop near me called hybridynamics that has a dyno and is very known for performance tuning. But my question is does anyone run the nitrous set up? and if so what set up? Keith

you might post this question in the n/a w/ aftermarket forced induction forum also as i think some people consider NO2 a type of forced induction. That way you will get answers from two pools of people and it will be relevant in both forums. And I hope this thread doesnt turn into a "NO2 is/ins't forced induction" debate.

You should build the motor to handle the nitrous you're looking to run.

I DO plan to build an ALL MOTOR w/ nitrous NA monster in the future sometime with higher CR pistons, STi rods, upgraded oil pump, and stick it into my WRX swap. I'll just have to plug up the turbo oil feed and coolant.

If you want it to run nitrous, build it to handle it. Running stock stuff will not handle long. I've been through running the car hard with stock stuff. Things begin to break because they can't handle it. The transmission for instance.

If running on stock engine, I wouldn't go more than 70shot.

i agree with fuji k. the engine should be built stronger to handle the nitrous. once u do that there shouldn't be a problem. good luck

i dont see there being any problem running like a 65 shot on the stock motor. im not talking about running all the time. with the right tune i think i should be fine with out building it. i use to run a 75 shot on my acura stock untuned with just bolt on on it and never had a problem.

i have not heard of many people doing NOS. if it worked for u on another motor, the try it i guess. to be safe keep it around the 75HP shot. if u really want good power, save the money and turbo the car. do the cat soon. try a pulley and grounding kit if u want to. good luck with it.

the cats will be gone next week, and i already have the perrin crank pully, alone with the apex i n1 exhaust and the top speed header. only wanna do a 65 shot for fun and it should put me around 215 to 230 hp

You people crack me up! I have the same cats on since I purchased my Impreza in late 1996. It has had way more than its share of juice.

Put your baby on the bottle. Keep the shots between 50-65hp. Do not hit the nitrous coming out of the hole (like I did). This is all for now.
