Default What shot (dry) nitrous is safe on stock WRX?

First I'd like to say hi to everyone, as this is my first post

I currently own a Corvette and I am considering a used WRX as a daily driver for this summer which will include some long commutes.

Question: What is a safe DRY shot of nitrous to run on these cars? (2.0 WRX turbo)

Perhaps one of you could point me in the direction concerning nitrous applications on these cars?

thanks

Well considering that the max dry shot possible in ANY setup is about a 75 shot, I'd say that's about right.

thanks, given the size of the engine, I was assuming around that. I have ran 100shot pills on the Corvette, and 150shot wet setup.

I tend to like dry setups more for street use in case anyone was wondering why I'd go with a dry setup.

How does the WRX generally respond to nitrous? Anything in particular or anything different about the WRX when it comes to nitrous?

Try to PM AzScoobie/Kingpin (aka Clark Turner). I believe he's a big fan of N2O.

My reading out here leads me to believe 50 shot wet is pretty safe bet. Do a search on this. It has been discussed to death. Search for AzScoobie and NOS.

Good luck!

I haven't heard of any special considerations that need to be taken into account when putting a N20 setup on a WRX, but that's not surprising, because you'll find that (generally speaking) the WRX crowd is not big on nitrous (so it's not discussed often).

With a stock WRX as a starting point though, it's very easy to find lots of power with a few exhaust mods + some engine management.


Any reason why you are thinking about nitrous right off the bat as your plan of action?
Just curious, as most people start elsewhere.

to run a dry shot or a wet shot in a wrx a new 255 lph pump will be nessary for more fuel. the stock pump wont be able to keep up with the pressure

Run wet or run real lean and boom. So I gather.

I suspect the biggest reason the wrx crowd doesn't favor nitrous is image (whether its the cheater image or the unreliability image). Its still the biggest bang-for-the-buck mod, and the ONLY way you're going to significantly improve low end and spool characteristics on a wrx.

I most def have plans for other mods as well, but I already have several nitrous setups laying around...might as well make use of them.

I personally think 1 big reason that nitrous is not popular is because of the pure ignorance factor. Many people have absolutely NO idea what nitrous even is, let alone how it works. I read time and again... 'dude, nitrous is bad! how can you say injecting a flammable liquid into your motor is safe!?!'

In the grand scheme of things I may be wrong, but I personally feel nitrous is just as 'safe' as any forced induction application.

I have seen 50 shot Dry setups used without issue. The Stock Car is very rich to start with so there is some room in there. WRX's gain 2-4 psi in boost with a 50 shot so you might want a boost control of somekind. A bone stock car with a 75 shot will run 12.7-12.8 @ 100mph or so. I have seen this with my own eyes.

On my car a 50 shot takes .5 to 1 full second off the time and adds 5mph. I use a wet kit. I have sprayed up to a 90 shot on my JDM motor which is stronger. I sprayed a 90shot on my 2.5 motor with GT30R turbo. Clutch would not hold.

On a WRX a 50 shot is worth up to 75whp. Nitrous is alot of fun and its a great back for the buck. I dont know why WRX owners dont use it. I think its because they have never setup a kit and used it so they are scared.

2 years ago my WRX was running 12.7's over and over and over.. Right around 109mph. I tossed in a gallon of C16 and sprayed a 50 shot but with one step leaner fuel jet. Results where an instant 11.82 @ 117mph and go booted off the track. 1.6 flat sixty ft time..

I see you have some actual hands on experience with nitrous and the WRX, thats great.

With your experience and this car, would you recommend ever using the dry setup @ 75 shot, or is this the sort of car that really needs to be ran wet?

Also, assume 50 shot dry, how extreme can you go with mods before you start having issues with the dry setup?

Dear GOD man, do you know what would happen if something accidentally caught FIRE in your combustion chambers?!!












(I should clarify this statement, I do understand that Nitrous Oxide is nonflammable and acts only as an oxidiser and a buffer in the combustion process.)

dont do a dry shot on a wrx. unless its very VERY small. use a nice wet set up, and direct port would be a big plus. and also use a window switch so it can only spray between say 2500 -7200 rpms so you dont mess your chit up.
