Default Nitrous use on a subie?

Is there a reason, no one runs nitrous on a subie. I always thought nitrous+ boost would be too complex, but I've read on some local forums guys with speed3s and tc cobalts have nitrous set ups. Only thing I found was nitrous to spool big turbo setups but not added power?!

Call me lame but I'd like the idea of having a good 30r sized turbo with the ability to have 35r power.

There is no reason that it cant be done. Most people dont want to bother because nitrous isnt that safe and isnt worth the headache unless u are trying to make the fastest subaru in america or have endless bank. it is just not worth the headache. you are better off running meth to make safe hp increases. If you want knock yourself and your motor out lol

I always thought nitrous is the cheaper route than most upgrades, hence why it's so popular

Regardless you have to retune your car for it. you will only get the 75 non reliable hp when u spray as opposed to spending a grand on a nice turbo and making that power all day everyday. its cheap power for na cars not cars that are allready turboed. Nitrous also has a faster burn characteristic so you would need a seperate tune and a way to switch back and forth from map to map. If you drive on the same nitrous map when u arent spraying you will loose a lot of hp cruising daily cause you have to retard the ecu to run the nos. There is a lot of reasons no one is doing it.

As safe as a turbo LOL. Ok drive to your local road coarse track and spray nitrous for 8 hours straight and report back to me. Nitrous is more dangerous then not running nitrous..any hp increase is. But to say that nitrous is as safe as a turbo kit is a joke and makes you sound stupid. Can nitrous be ran in short bursts repeatedly on a solid tune ABSOLUTELY. That doesnt mean its reliable as a non nitrous car. Meth is safe to run all day everyday. Spray nitrous all day everyday stop light to stop light apex to apex and then come see me.

People already switch maps from pump to e85, race gas. That's not that big of an issue, and an extra 75 might not sound like a lot but 425 to 500 whp sound pretty nice to me if it were possibel

Obviously you won't be doing that everywhere you go, just times you go to the track. I really don't know why nitrous is such taboo?!

nitrous can be used on a road course but really its only for drag racing and yes it as safe as a turbo check the number of people that blow up their cars due to too much boost to the amount of people the blow it up from nitrous

My 10lb tank used to be good for three minutes of a 60 shot. Think about how fast you can go through 3 minutes of squeeze. It cost me about $33 to refill plus the time to run down there etc.

I must have run 100 or more tanks through my Honda and another 50-60 through a 150 shot on my mustang.

100 tanks @ 33 = 3300 in squeeze for 300 minutes or 5 hours of fun and is WAS fun, but it was never cheap.

I love the squeeze and the only problem I ever had with it was finding traction in first gear, but it adds up.

turbos are actually cheaper in the long run...

Now if your running a cheater system and betting heavily on illegal street racing it might be worth every penny, but I am not.

Hope my experiences help

Ugh, just stop.

Adding nitrous and adding a turbo are doing the same thing, adding more oxygen into the intake charge.

Nitrous has a bad reputation because people a.) install it wrong b.) don't tune it correctly c.) abuse it.

A straight comparison of nitrous vs. boost use isn't a direct comparison anyway. With nitrous, the extra combustible air is instantly available. It would be like your turbo being on a switch, where it either provided 20psi or nothing at all. If you were constantly running peak boost, including off idle, of course that would be terrible for your engine.

Safe nitrous use is just about using it intelligently, all there is to it.

I'm really looking into a cheater spool up type set up, having my destroked motor soon, thinking about 5862 maybe 6262 and having the nitrous kickstart the turbo. Waiting to see if the lag will be that bad in the first place

I know plenty of guys here that have big turbo V8's and use the nitrous to spool the turbo off the line. As people have said, if nitrous is tuned and installed properly it can be very safe for the motor. It was even used in WW2 fighter jets. The problem is most people dont tune properly for nitrous and lean out and things go wrong.

With respect to the "switch thing" there are quite a few progressive nitrous kits out there. You have about the same level of control as you do with a meth injection kit, if you pay for it and want it.

I have always had single stage wet and dry kits, but I have certainly seen multi stage kits and other solutions to the light switch issue.

Well the last time I bought a tank was before I bought my first WRX so that would have been back in 2002, so I am not sure how pricing has changed in a decade. < old fart...

Nitrous is safe if done right and you are willing to spend the money on the controllers. Nitrous also isn't damaging if ran with proper window switches and safety nets. But this isn't the key to power for everyone.

Say I am running something a lot bigger then a 35r.....40+ something, this is a application where nitrous can help. Say i am running a new GTX30R or below......don't bother using nitrous.....you just can't shift that fast sorry. Maybe with a dogbox.

Also you aren't going to get the true potential using nitrous +93pump. Just run Meth if this is your plan.

Let me give you a break down of Nitrous users ....
Dumb idiots and Professional drag users....there is no middle ground, No gray area. So please tell me which are you?

You want Nitrous ....spend big, buy a stand alone if you can afford it. READ ALOT!!

I've used nitrous on several cars and have never blown one. I have also run a 20lb bottle through a toyota 18rg on the way home from work. Done right it is safe. If that is what you want to run tune for it.

Done right, nitrous will be more than a turbo upgrade, and a turbo has a 50K mile+ life span. The turbo keeps giving, and the nitrous bottle keeps giving out.

Have to dispute this. With nitrous, the extra combustible air is instantly available, when you have the bottle filled, and the temperature/pressure is right, and everything is activated, and your timing is reduced, fittings are tight and not leaking, you have the correct failsafes in place so that your IM doesn't end up in your hood scoop, etc.

With a turbo, I can start up the car, get it warm, and there is the power.

Adding a turbo kit to a non-turbo car, vs. adding nitrous, different ballgame, but with the OEM management and failsafes in place, I don't see the reason unless, like stated earlier, you need the spool, you need the money, or you want it.

The same can be said about a turbo, tunes gotta be right, no boost leaks, it's all in the setup. It's just picking whatever suits you best.
