I want to add power to my 99 A4 but I want to keep it on the cheap side (less than $1000). I have done some of the usual mods, Corsa Indy's, Blackwing but I want something in the order of 50hp. I am aware that if used improperly, it can be hard on your engine but I was wondering if anyone has found a system that is easy to install and safe.

 

First Nitrous Oxide is N2O not NO2.

Nitrous is a less expensive alternative, not necessarily the cheap way to add power. Its easy to get into the $1500-$2000 range with nitrous accessories.

A basic NX wet kit is 529.00 + Gen II upgrade $400.00 = $929.00.
if you add a remote bottle opener 200.00
NX electric gauge + fuel pressure guage + a pilar guage pod = 500.00
NX switches = $52.00.

At the end you are around 1700.00 (estimated) to do a complete nitrous set up. If you are good with wiring you shouldnt have a problem. If you have any questions feel free to IM me or visit my store http://www.nitrous4less.com

BTW- you will barely feel a 50 shot, you will want to go 100.

 

Thanks for the N2O heads up. As you can see, I know nothing of the true details of nitrous. My main concern is for the durability of the car. I don't want to damage the tranny or fry the pistons. Also, I would want a system that is inconspicuos.

 

As long as you dont go lean, you wont damage a piston. Also keeping your shot lower will decrease cylinder pressure. I have a tech & general questions Q&A on my site.

BIG99, you don't have to spend all that money on a n2o kit. For example, I spent $450.00 on a NOS brand #5177kit (brand new). It has everything a guy needs to run a very safe and reliable set-up. Compare what you get in the kit for the price and you will see that this kit is a bargan, not to mention that many, many guys are running it. Check out ls1.com and ls1tech.com and go to their nitrous sections and you will see the 5177 is used on the ls1's a lot (do a search). It is also a kit that you can install with out a retune because it is rated hp wise at the crank, very, very safe install. It comes with all the safety stuff and a n20 gage, amongest other stuff. The only thing you might want to add if money is a issue is a bottle heater for more consistant operation. I don't sell n2o stuff, so this has nothing to do with lining my pockets, just trying to let you know what's out there. There are also other kits and companys to check out before buying, so good luck on your purchase.

Please be aware though that you will still need a blowdown tube for safety reasons. This is also a requirement if you goto the track. A bottle heater is also beneficial for keeping pressure consistant. A purge, besides for being just fun, is also a benefit to eliminate excess air from the N2O line. All this comes in the gen x II upgrade.

The remote bottle opener is a great for impromptu racing on the street. Anyone who has used N2O in the past knows the pain of not having the bottle open when someone in a viper wants some.

Since most C5 owners put the bottle in the rear center compartment, how will you know what your pressure is? You want a a-pilar N2O guage. You also need a place to put the guage, so you will need the a pilar pod. Fuel pressure is critical to N2O, and is not offered on the DIC so a electric fuel pressure gauge is also a requirement.

The only part that is a complete accessory is the switch panel. But if you have gone this far, this switch panel looks awesome.

My business venture is not going to 'line my pockets'. If you look at my prices I have the best prices on the web. There isnt much mark up on Nitrous kits, since its a supply and demand principle.

The NOS dry kit will always be cheaper than the NX wet kit. The wet kit has an extra solenoid, braided line, plus fittings. However tuning a wet kit to produce more power is easier since all you have to do is change jets.

Big99, because you don't want to spend a fortune, like I said most of the stuff in the gen-x is not needed and just price boosting stuff as other kits include most of it. Compare for your self what is in the kits.

Since the 5177 uses dual n2o solenoids you can leave the bottle open all the time, I do. Just make sure you you make up some bubble spray (dish soap/h2o) and check all your fittings for leaks and you'll be fine. But if you want to spend the $ that's ok too.

Unless your really into drag racing and need to really know your pressure, with the safety stuff in 5177 you can get away from needing a gage at the dash. But if you really want one move the 5177's bottle pressure gage where ever you want. You don't need the pillar pod as many guys put the gage in the ash tray area with the switches. Same with the fuel gage, if you use a hobbs switch (FPSS), which is included in the 5177, it will shut the n2o down if you have fuel problems, so you don't have to monitor unless you want to.

All switches and relays are also included in the 5177.

The 5177 kit also includes a 15 pound bottle. Most guys turn in in for a 10 pounder and a credit of $100 or so dollars that is turned into other n2o goodies. Also the quality braided line is extra long, so you can cut 6 feet off the end and have a new fitting put on (at any hydraulic supply outfit) and have extra hose to run custom what ever, I did this and used the extra else were in my n2o set-up.

The 5177 also includes a pop off valve and a blow down tube, a legal NHRA, IHRA drag kit.

A purge is nice, but not needed, as you can do the same (and many do) by activating n2o breifly (just a split second while you do burn out). This will clear the lines and you are ready. On the street you don't have to worry about it. You can buy a solenoid and build your own for a lot less than a pre made kit, I made one and it is nice having the "Dual Bulls Nostril" shot over the windsheild. Check out this site for purge kits and parts http://www.speedshop.org


This kit is truly a bargan and a fine kit at that. No re-tunes needed, but I always recomend it anyway just to be safe, most don't. The other kits are ok too, but a lot more moola. Here's another site to check out http://home.ican.net/~jsetter/nitrous.html

I'm always ready for the Vipers as my kit is set up to be on/ready at all times when the ignition is on, so, when ever I get in car it's online cause I leave the bottle open (dual inline n2o solenoids) and arming/heater switches on, (switched 12v).

The last thing, the NOS dry kit is cheaper because Holley is a giant of a company and can out buy the little guys (they bought NOS) meaning they have purchasing power. Oh yea NOS has been around for about 20 years and always the inovator and if I remember correctly the guy or people who started NX came from NOS or something like that.

I fixed the second link/address so it will work. It has some really good info on using n2o on the ls1, it was written up concerning F-Bodys but applies to the Vette also, check it out.
