nitrous on stock

[silverbullet]

I'm trying to figure out a way to get the most for the least... aren't we all !!!
Well I'd like to mod the engine properly so that in a month or so I won't have to replace the engine or call the fire department.

Currently the wheels on it are fine. The currently engine is an ecotec 2.4... well its a 4 cylinder 5 speed so it goes faster than snot on a cold canadian winter's day... and that's fast. If anyone has any tech info... english not techese.. I'd greatly appreciate it.

When GM was testing the ECOTEC for drag racing, they originally started using nitrous, and kept adding more and more until the engine finally broke something, easiest way to figure out weak points in a car. The rods were the first to go, at something like ~280HP, which would mean roughly a 140 shot of N20. That is definately too risky though, because you'd be pretty much guaranteed to blow your engine...

To keep things safe, I'd say a 75 shot of N20 would be plenty to try at first. If you're feeling brave, perhaps a 100 shot? I really don't know much about nitrous though.. but apparently wet systems are safer than dry systems... hopefully somebody else on the forums can help you out with that more than me...

And definately it sounds like you need to learn a lot more before you go installing a nitrous kit. "Currently the wheels on it are fine.".... <_< Well ok, if you say so.... :blink: But I don't know what you think that has to do with your engine...

And you better be sure that its a 2.2 ECOTEC, and not a 2.4 Twin Cam, because the Twin Cam would probably blow up shortly after a 50 shot of N20...

Read the Ecotec Turbo (http://invision.aleromod.com/index.php?showtopic=204) thread for information. I'd contact companies who'll be involved (Nitrous companies, local shops who'll probably install it, etc...) to see what they recommend. At least this way, you can see the big picture from everyone's point of view.

ya i agree with the rest of the guys first need to find out if it`s the ecotec or the 2.4 then go from there
my ecotec has simple bolt on mod`s that really helped out allot
if your not sure ask us first

The eco can not handle a dry 75 shot in a stock motor ( I know this from personal experience) I recomend high compression pistons, upgrated cam shaft and a new head to make nitrous work effedtive in the eco.

heh heh :thumbsup:

Hey silver, have you also considered a supercharger? Some people prefer to have the power all the time as opposed to the push of a button or flip of a switch. It could be more reliable and less likely to blow your engine. It's pricey though :o

Google search for "2.2L Ecotec Supercharger" (http://www.google.ca/search?q=2.2L+Ecotec+Supercharger&ie=UTF-8&oe=UTF-8&hl=en&meta=)

^^^^very true havik.....but that is one costly sob!!!! if i had nos i would just use it only for racin purpose`s only....the spped shop out here told me a wet shot of 75 hp
imo only if used here and there the block should handle it
my 2 cents

I have concidered adding NOS to my car, its a 2.2L ecotec all stock....I know Springs has played around w/ different types of shots of NOS....the general concensus is a wet system is safer than a dry....is it actually safe in your opinion to throw a bolt on NOS system to a stock engine with say a 50 or 75 shot of NOS? I guess im asking how much of an engine life should I expect if I only use it for racing purposes?

[havik]

I wouldn't recommend bolting on a NOS system to a stock engine, simply because in the long run you'll blow your engine (it'll happen)

[chicken_dog]

i used it 3 times and mine blew!!

[Naich]

was it a wet kit or a dry kit?

[havik]

chad (chicken_dog) had the dry kit (I believe)

[velocity]

Just FYI...according to the getrag website the 287 can hold up to 250Nm of torque. Or about 170-180 ft-lbs. If I remember correctly the ecotec puts out about 150 ft-lbs as it is. With a 75 shot of NOS you would pretty easily add over 30 ft-lbs of torque as well and blow your tranny. :D

[Final-Reality]

It'll hold up alright velocity, people run way more power than that through the getrag... it's just the clutch that isnt up to the task

Verry true, i beleave that the stock clutch is only good till like 140-150hp & torque
Cant wait till the centerforce comes out...if it hasnt yet...lol

^ heh thats tru, my motor blew up on a 75 after about 15 seconds of use.

[dopey]

^^^ thought u said u werent spraying when u blew ur motor???

get ur story straight dude.......

[Final-Reality]

He's lied so much about it that he forgets how the true story goes.. :rolleyes:

[dopey]

^^^^ good call dude

[jonez]

But I am sure he will try changing his story again.

[umplumpa10]

ok I'm surprised this comment didnt come from Sweet already, but the title of this post is "nitrous on stock........or can be done with a few mods".......does that seem a little contradictory to anyone else?? ;) To me, any mods to the engine would basically mean its not stock. But maybe thats just me.

[dopey]

well in my opinion... adding nos to a stock motor isnt really a mod...... its more like putting a ticking time bomb on ur motor......

go ahead and do it if u want....... but im betting its gonna go BOOM sooner or later

[havik]

^^ agreed

DO NOT ADD NOS TO A STOCK MOTOR!!! <_<

Ok tired of the fear nitrous speeches so here oges my expierence. I had a 96 chevy cavalier 2.2 ohv with a 75 shot. It is a zex kit at push button response and not by rpms. Had the car three years at 160,000 miles and only had to rebuild the engine once. (only needed rings and probally from the many miles) THere is that story.

As for my new found alero. I have started with a 55 shot from my zex kit and no problems. RUN NITROUS ONCE AND CHECK PLUGS. If you get white plugs don't use it. I also put in a stock K & N filter replacement for more air flow.

Things I have learned with my nitrous expierence.
(1) Have more air flow in and out your engine if possible.
(2) Start with a small shot and see how it does.
(3) Do not spray every weekend, give the car a break.
(4) Only spray when your foot is to the floor so you know the fuel is there.
(5) Listen for pinging noises, if you get them your not getting enough fuel.
(6) DO NOT use below 93 octane or you will get those pinging noises(detonation).

Every one in forums scared me from using this stuff way back when then my friend sprayed a 75 dry shot a 1.6 type r motor. Needless to say I am ok with it now. If you have any questions I will try to answer them regarding nitrous or anything else. And if I blow a motor or my winshield wipers quit working because I use nitrous I will glady tell everyone here and hopefully show what blew and why.

Fear nitrous speeches?

Nobody here is saying nitrous is a bad idea, nor are we attempting to scare anyone away from it. We're just noting the obvious, that adding nitrous to stock motors is a bad idea.

Welcome to the forums btw

Good post there dude on Nos, I would have to agree on most points, and add that that normally applies for most major engine mods, whether it be spray, blowers, or boost. Fuel Management is key! You also may wanna completely overhaul your injectors and fuel pump for some bigger ones... Let us know how it goes...

[JonE]

By the way have pictures of my zex install if any one wants a how to guide made out of em. And so far nothing has blown up on a 65 shot.

[havik]

Hey, do you have a place to store the pics? Cause I can store them on a site and we can create a thread that links to them. Pm me if your interested.
