Another nitrous question

[bostonhatcher]

You're going to need a Wideband when you tune your nitrous. You can leave your stock timing as long as you richen your nitrous tune. Most target nitrous afr's are 11.7/11.8:1. If you don't adjust timing you can richen it to low to mid 11 to 1. Also, to tune it, you change out your FUEL jet (bigger for richer, smaller for leaner). Run colder plugs, and high octane fuel to prevent detonation.


As many bolt-on's as possible will definitely let your motor run hard on nitrous.


Compression check is all you need. The 420a's have the MLS head gasket stock so you won't blow one of those. By all means don't go over a 75 shot.

 

[white90gsx]

yea im def not looking to blow it up.

 

[BigRand]

I'll never encourage anyone NOT to get a wideband, because honeslty its nice to know exactly what your car is doing while forcing it to work harder with nitrous or turbo.

However with a wet kit, the extra fuel from that should over compensate the amount of fuel actually needed to run that 75shot.

If I were looking to save money while doing what your doing, I would take it to a dyno and do a couple of pulls and have them put their wideband in to check the air/fuels during the nitrous shot.

That way you can tell how effecient the wet kit is (or direct port), learn how much horsepower you gained, and have that reassurence that those extra fuel jets are doing their job.

Also remember... with NOS.... this is a flammable substance... So before you use, and even after you use... make sure you check and double check things are working properly. I saw a friends Civic blow the hell up because the Valve stuck open... and kept spraying and spraying... and BOOM!

Play with this as if you'd play with a girl without a condom... You understand and very well know the consequences of your actions... but you still want to hit it!

Nitrous oxide itself, is not flammable. That is a common misconception. However, after it is heated up (sprayed into a motor/etc.) in an enclosed area, when the molecules seperate, you have two effects. More combustion, from the extra oxygen molecules and a cooling effect, from the breakdown of the molecules. So you get lower temps, and more combustion.

Oh, and InfiniteGSX, I LOVE your avatar. Very b/a.

What the hell is it with my new Avatar... Your like the 20th person to say that! I'm just getting back in touch with my PS'ing days... PM if interested I guess ... I need some practice work...

white90gsx, Sorry for hyjacking your thread.

I was told that it is a chemical that just makes fuel "More" flammable... Sorry for the inproper info. Still, something involving the NOS on that civic blew up and things went up in flames! It sent a jet of flames through his intake pipe and his filter... well it was a ball of crust...

 

[Shadow98]

Can we please stop calling it NOS and call it nitrous. You guys sound like a bunch of ricers, .

You can thank the original fast n furious movie for adding to that misconception

however a bullet to a Nitrous bottle might do a number on an eclipse.

 

[white90gsx]

....yea im going to finish with the small mods first this week and then pick up the kit i found a kit for like 400 still in the package...Now should i go direct port or just in the manifold?

 

[white90gsx]

hey is there any techs on installation i only found the one with the zex kit that automaticly sprays at wot but i have a different kit.......and cant i put the jets on top of the intake manifold instead of in the cai?

Does that involve a long story and a 10 mile hike home? hahaahaha

 

[white90gsx]

Huh?

 

[InfiniteGSX]

Huh?

Guns... Asians... Bikes... Green Non Turbo Eclipse... Paul Walker... Vin Diesil... Is that even how you spell his last name?

You need any more clues? He mentioned rice and a bullet in a n2o tank... so I brought up something that was on The Fast And The Furious... I like making fun!

Josh, you should be working on your car, not post whoring, . I guess I should be too, but I have some posting to do before going back at it. And, yes, I know, i'm werid for working on my car overnight, but I work overnight and it's cooler too.

I try, but I get attacked by Mosquito's! Plus I can't get the car running till sometime tomorrow... I miss my garage!

 

[BigRand]

you can tap the jets where ever you want, but if you do tap them on the intake manifold, DON'T FORGET TO IT WITH THE INTAKE MANIFOLD OFF THE CAR, so you dont' get shavings in your combustion chamber.

However I don't know if you plan on selling the car when you get your co-signer, I would probably just tap the intake pipe, incase I wanted to keep my nitrous kit for my next car, and not have to leave a whole in the intake manifold.......I know its less efffeciant, but I guess It depends on your long term goals.

 

[white90gsx]

well i found a co-singer but i went to test drive the 95 tsi and the damn thing was a mess its leaking oil from the oil return line and the auto tranny has no first gear and the guy wants 6700 for it i laugh when he told me that.. So im just gonna save some money here and there until i can just pay cash right out...But any way yea i know to take the intake manifold off because of the shavings but hooking the jets up to the cai seems kind of a waist dont it? Could i put the jets right in front of the tb?

 

[Shadow98]

I'm pretty sure that what Rand ment when he said to put the jets on the intake pipe or in your case CAI. Tap it to where the jets are in front of the TB, around 5" away.

 

[BigRand]

^^^^correct, if you follow the instructions on the wet kit, they'll tell you to put tap the intake about 3-6" away from the Throttle body.

White90GSX not to discourage but I was reading and this dosent really seem like a "cheap" way to pick up some hp to me. But best of luck with it.

 

[white90gsx]

well i got a kit for 400 brand new still in box and wrappers plus the way i look at it is the kit can be used for the next car and the next.

 

[KazooGS-T]

White90GSX not to discourage but I was reading and this dosent really seem like a "cheap" way to pick up some hp to me. But best of luck with it.

Ha ha,right. I picked up 175 horsepower last night, for $30. Seems very cheap to me.

 

[Cobrasatellite]

Kazoo good job for 30 bucks. I picked up a pretty consistant extra 95hh for about 427.83. Cause you see when the turbo spools, it makes power the whole time, and I dont ever have to refill the bottle. (this is how much my turbo swap cost)
Like I said no discourage intended. I just think he after a new clutch, exhaust, and Nitro it sounds like alot of money into a car he dont really want. Ide just save it and use it on the dsm he "wants". And if you know nitro its not the ones who know it that have problems its the 1s that are new to it. And 90GSX doesnt sound like hes played with it to much, and there are better ways to spend 400 bucks on nitro that you can ONLY RUN AT THE TRACK so it dosent really help his goal of making the car actually faster. (on a regular basis) It works but only for a second.

 

[KazooGS-T]

Well, unlike in a 1st Gen 2.0, we can't just do that. If he were to turbo, it would cost a lot more money. Only other mods that would be noticable, power wise for CHEAP are: Underdrive Pulley, I have an AFX and love it. Or, cams. But those are not necessarily cheap. Best two mods, bang for the buck wise. Other than that nitrous, is simply the cheapest way to pick up extra horsepower. Yes, you have to fill the bottle every now and again, some more than others; but HP to $ wise, excluding the cost of the kit itself, there is no other mod equivalent, hands down.
