Hey, it's your engine. Go for it. You can get the same power with a catless turboback exhaust and boost controller, or better yet a TBE and computer (UTEC, reflash, etc.) for more power. And that power would be all day long without refill of a bottle.

Noob! Nitrous can be done safely as long as the owner has a clue what he's doing.

TonySTI, if you know what you're doing with nitrous and know how to use it safely, especially on a car like the STi, then more power to you. Just remember that there is always that chance that...well, you know. The only time I'd use nitrous is if I had a nitrous cooler core attached to the intercooler.

Just curious, what would be your intentions on NOS'ing an STi? I'd assume drag racing as I have yet see someone Auto X or road race with nitrous in constant use.

Yeah, you could get 30+ HP with exhaust, MBC, UTEC (in 6 months), etc... but then you can still add NOS and get another 50HP!

The more I read about NOS, the more I think about trying it. Drag Racing is certainly the best place for it... But getting that extra acceleration on the highway would be a nice kick in the pants too!

This should be a safe mod as long as it's carefully dialed in.

I'm pretty certain NOS is illegal in SCCA autocrosses......

Assuming he knew what he was doing, and knew enoguh to do it safely (ie: he's had real experience with nitrous) he shouldn't have to ask us about it.

If your going to put NAWZ on the STI you may as well buy the Fast and the Furious brans NAWS since its the best (avalible @ Summit Racing). Also dont forget to buy Fast and the Furious brand floormats, steering wheel covors, and neon lights for your undercarrige.

if you are plagued with Det problem, will you still risk it anyway?

what a good way to void your warranty.

The cooling effect of N2O can actually help prevent detonation. Just be sure to set it up properly.

If NX or NOS built a kit specifically for the USDM STi, I'd be willing to give it a try.

N2O is only legal on the drag strip. No sanctioning body (SCCA, NASA, etc) allows any chemical bottles (N2O, CO2, etc). Plus, bonus, its not legal on the street... most jurisdictions are claming down. I say go for it, we can start a betting pool which will happen first, blown motor or impounded car

If folks are afraid of an unfamiliar power source, maybe modding the STi isn't for them.

The only way the authorities are going to find your Nitrous setup is if you do something really stupid like street racing and get your car impounded. If you get pulled over for speeding, I don't envision the cop asking to see under your hood. They can't search your car unless you give them permission or you're getting arrested or they think their safety is in jeopardy.

The only way you're going to blow up your engine is a bad setup and improper use.

A progressive setup with a 50HP hit isn't going to kill the engine any more than an AVO450 or 20G turbo will.

As for warranty violations... you're doing the same thing with an ECU mod, turbo, MBC, etc. What would one do if they threw a rod with an MBC installed?

Tell you what... Let's start a pool. Everyone sent me $10 towards a Nitrous kit and a calendar date. If I blow the engine or tranny within a year, I'll send the person with the closest date $300.

Please don't knock what other people do with their cars...

I'm going to lower mine a bit, add 100hp or so, slap race pads, fluid and rubber on it and take it road racing.

Some people will never take theirs above 100mph. Some will drag race. Some will put theirs in shows. Others will Autocross 'em. A tiny few will run rally's with them.

Each to their own.

It's a wonderful, powerful, goofy looking car that's a ball to drive.

Every individual is different. Sorry if I and others don't conform to your view of the WRX/STi tradition.

Yes, it is just a machine. If you have the dinero and the time, test its limits. It seems to me that the engine block can withstand some more applied power and heat. Someone knowledgable in NO2 use, please correct me if I'm wrong - but a semi-closed deck, forged pistons, conrods, and crank is a good candidate for nitrous oxide. When I had my 99 RS, I met another 99 RS owner who had installed a 75 shot of NO2 without even opening the block. I told him he was brave because the strength of the RS block was always an issue for that car. That car comes 165 hp at the crank stock. Jumping up 75 hp via NO2 is a big jump. The STI has 300 hp at the crank. A 50 hp jump for the STI isn't too bad, relative to the RS. The STIs engine and tranny could most likely withstand the extra power. The extra heat and potential for pinging on an already pingaphobic engine would concern me. Nitrous tuners probably know how to resolve those issues.

If anyone does go the nitrous route, please post about it.
