i need some info on nos...... help!!

I have a 2005 aveo lt and I have been wanting to make it a mega sleeper car and i have ran by every idea from dropping in a turbo to doing an engine swap but i dont have the time or the money to do a complete rebuild to do all of that so i have been considering beefing up the head gasket and head studs and running 100 to 150 shots but im affraid that im just going to blow my car up and be completly screwed. what scares me the most is that i really dont know what i can push on stock so i dont know how much i need to do to be able to make this work... if any one can help me it would be appreciated.

I am not an expert but you should take it to someone who can do it properly because My friend who attended a car show in Baton Rouge Louisiana Last year watched what doing it improperly can do to a car A rarely driven 2006 Pontiac GTO with only 3,000 Miles blew out all the windows and the driver was blown out the roof. What happened was he put the Nos in and didn't tighten the bolts to the engine and when he pushed the button the car's radio shot out of the car and landed in the College Drive Walmart Parking Lot. Do it safely but becareful not to rush.

Just remember the trannie in the Aveo is only good for 220hp, after that well [-X

Way too high a shot for a stock motor like this. Honestly, best bet if you are dead set on it would be a small 50-75 shot plate system. I wouldn't though....Nitrous is for experts that really understand all the characteristics of it. It doesn't work like "The Fast and The Furious" where you just push a button and go...there's a lot to it. Nitrous is very dangerous, boost can be just as dangerous when the turbo, plumbing, wiring and tuning aren't done correctly. You should put your money and time into the bread and butter of performance with your car, like starting with intake, exhaust, cams and other internals.

Wolf, you might want to ellaborate on "other internals" and about cams, do we have any aftermarket options available to us or are they only done by shops on one-by-one basis?

forged rods, options of different pistons with various compression ratios and diameters, different grinds of cams, etc are available through a few sources.. i don't think to many have experimented with stroker kits or anything...

honestly in my opinion, short cuts like nitrous on a stock engine are really a bad idea. but when you build a performance engine you need to build it with nitrous in mind just like you build an engine with plans to turbo it.

Exactly! +1

but if one was inclined to us this gas, then a 50 shot is all that you would want to use, i would not even think of a larger shot

Actually you can run as much hp as you want, it's not hp that kills transmissions, it's torque.

You dont want more then 185ish lb-ft of torque at the wheels on your D16 else it wont last too long.

my step dad keeps wanting to put a 50 shot on my car :P

if i were to find a cheap kit, i would use it as a learning experience, he does have a lot of experience with it himself

Honestly, if it's not in a race setup I wouldn't bother. When you think about it, the best way to use nitrous on a 4cyl. motor is direct port injection, in which case you are basically looking at building a bottom end with stronger internals, which basically means while its apart you'd want to set up a turbo which is what you should've done right off the bat. So, without extensive work to the motor your best bet is a plate system ie. throttle body injection aka dry manifold or wet manifold injection, which is more or less a waste of time for the cost and little power gain. You're talking even with a 40-60 dry shot you're looking at having to upgrade the fuel system, probably narrow the gap on your plugs and would probably always have to run 92 octane. No thanks. I only run No2 in my Daytona to spool my turbo, as you can make a lot more power with boost than nitrous when it's done right. Just my .02. Did I miss anything Rabbit? :lol:

why are you asking me :P ?

read up how it works as in what it does for the compression / ignition stroke of the engine and decide from there. but wolf is right, you build with it in mind. just like you could bolt on a turbo and run like 3-4 psi without proper tuning, just you could run nos and run a small shot and not kill yourself. BUT if you expect results, your going to go past stock capabilities.

just run the car on denatured alcohol, and blow it up that way. it will be as much fun for a few minutes.

or have an auto aveo and rot in the basement :o

well not that this is relevant because i decided against it but i was trying to find out what the stock engine was able to take so that i could build around the nos. i wasnt just planning on hooking it up and running it.. but thanks.

no one wants to do anything with the stock engine :x

I have no complaints about the EcoTec motor in my Aveo. I knew what I was getting when I bought the car and I researched the lack of aftermarket before I even went and test drove it. It's no race car, but it's pretty quick, and with a few suspension mods and new intake and exhaust it's a cheap 10K hot-hatch with go-kart handling...being a VW guy, I guess that's what matters to me. Speed and power mean nothing if you can't control the car.

i cant complain either, i dont want something fast, but i want a little more power without the hassle of a turbo, maybe get into the 16's with cams and such, and i will be happy

I don't care about 1/4mile times in the Aveo, that's what I have my mid-11's Dodge Daytona for. No, I care about track times, racing stability, and the ability to handle aggressive maneuvering in the mountain roads.

Don't be lying hunter, you DO want something fast... 8) Aveo just takes quite a bit of time and money to get there, and makes you wonder if it's worth it for that. But like Wolf said, if you are interested in something that will handle well with a little bit of modifying it than Aveo can do it for you for less money and time than it can go fast. :D Plus, IMO, it's a neat little car that with a few mods can look hot. My car has been called a "nice import" today at a muffler shop, but when I told them what it is they were surprised that "GM econobox can look that good" :D

I wonder how fast im going to be once im done...

Nemasys, you ARE one of the people I'm talking about who put a lot of time and money into an Aveo.. 8) The other ones would be "green moster" with the SC cobalt engine swap, Aveo Extreme, and GravanaTuning Red Aveo (they never hooked up their NOS though, just sold it with it and all the original parts they took off).

The green moster is sold by Jason right now for half of what they spent on it and it sits in the snow for most of the month... You're on your 3rd engine. :D Not everyone would be as dedicated to it. If you don't mind asking, how much did your whole project run you so far?

Well when my 1.6's timing belt went, my first 2.0 engine had a problem with it so it got changed under warranty and it didnt cost me anything. (1 year warranty from where i bought it)

The engine they sent me to replace the first 2.0 wasnt in good condition, both crank seals were leaking, got em changed under warranty but 1 of them never stopped leaking after that warranty expired.

The one im getting today is a 2007 engine with 31000 kms on it, i paid $552 CAD tax and shipping to my door included.

Total cost... well lets say i wasnt prepared when i 1st put the 2.0 in, ALOT of time wasted in getting the car in the garage, on the hoist, just to find theres a part missing, reassemble, off the hoist and back out the shop again (which is wasted labour i had to pay of course) then i had to buy the part and back to the shop again. I would say i spent $1000 too much on the job, mainly because of lost labour time.

As for parts, thats unavoidable if you want a 2.0, you will have to buy alot of parts to make it work, some you need to visit the dealer, some you can get at the junkyard.

These are rough estimates, (all prices in canadian dollars)
- Cost for engine and all the parts needed: roughly $1800
- Cost for labour and shop supplies: $2200 (alot of wasted time on labour, it took 36 hours of work... be prepared and make sure you have everything you need before taking it to the shop unless you do it yourself which i would have done but at the time i didnt have the tools and a place to do it, also it was in winter)
- D20 transmission: $250
- Full turbo kit cost: roughly $2000 (i had a good deal on this kit, installed it myself)
- New 2.0 engine: $552
- Performance clutch: $80 (used 6 puck ceramic clutch with 1500lb pressure plate from somone i know)
- Coolant, oil, plugs, brake fluid, power steering fluid, engine degreaser and soap to wash engine bay for the new motor: dunno yet lol

Granted i got unlucky with my first 2.0, and alot of wasted labour. I would have liked to do the job myself but it was impossible at the time. The new motor i am installing myself.

So if you discard the useless labour fees, your looking at roughly $4000 - $4500 to put in a 2.0 and turbocharge it properly. Add about $1000 if your willing to pay a shop to do the swap (not including turbo install, thats easy to do anyways)

So $5000 in upgrades... is it worth it?

- Mazdaspeed 3... 30-35 grand?
- Turbocharged 2.0L Aveo... 15-18 grand?

Watching the guy in the Speed 3 as you blow his doors off with a big fat smile on your face and hes almost crying to his momma??
