Ok, now this is making me want to put some giggly juice in my car.

I recently had a remanufactured 3.1 put in, and was told to "take it easy" in the beginning. I have put about 1,500 miles on it in the past month. Is it a good/bad idea to install a Nitrous Kit with this new engine in?

quote Originally posted by Mastermind: This statement is KEY. Anybody want to try and add up how much it would cost in nitrous to get 4.9 like performance out of a 2.8 continually punching it light to light driving everyday? Quite expensive I would think, much more than the cost of a 4.9 swap. The 4.9 gives you performance better than a 2.8 on nitrous all the time without the cost. Another reason some might opt for the 4.9 over the 2.8

All do respect mastermind, Were talking about Nos setups and ect, 4.9 was never in the posters thread.... He only wants to know the cost to stay on the bottle. This thread needs to stay clean.... There's good info on it.

Please stop shoving the 4.9 down everyones throat. Im not flaming you or anything but lets cut the crap. And let this die.... It's getting very old.

Retail from summit is around $380 plus handling I want to say. SH

That's a good deal. I was thinking your kit for sale, was for EFI. Cool of you to offer help with the install. That's the scariest part of NOS for those that dont know much about it.

Yeah that's a smoking deal, I will have to check friday to see how much extra cash I will have to do that.

Your choice? Your word is no good so we don't care what you say. And I'm very calm and you are nothing to get over. Take 'your' 4.9 and go away.

My apologies to the others in this thread, but I've been watching with interest.

I do have a question, though, and I figured I might as well ask now. When using nitrous, how much damage does using this do to an engine that's got a few miles on her yet runs great? I'm tempted, but I don't want to blow up my car. With NOS, I'm ignorant and happy to admit it. I've got a great running little 2.8 that I'm happy with and I'd hate to hear it blow apart.

Once again, I apologize for the idiot above. I'm suprised he's still around.

Fair enough, I'll explore this at another time.

Temptation is the root of all evil... aslong as you can resist the temptation and run a smaller shot 50 or so and use it moderatly you would see no excessive engine wear. If your talking near 200k miles that would be an issue.
I remember talking to a rep from NOS years ago and he said from testing on a 4cyl with a 50 shot , spraying 4-5 times a week 6-8 sec per time after 100k miles engine wear was nominal. Most screw up by using too much N2O, it is very easy to up the jets and increase power. When I first installed my kit on my series1 I was like "all I want is a 55 shot" well within a week I had a 100 shot in it and the 125 jets are on the way.

To be on the safe side, install the kit and get the A/F ratio checked at the local dyno. A lean condition will toast any engine in short order. This applies to turbos as well.

Jb1 gave some good advice, as soon as you get used to the 50 shot you WILL want more. Just like the turbo guys want just a little more boost.

If the A/F ratio is good with the nitrous (from dyno data) you will know what hp you can safely run. Each car is different, I have seen 2.8's that run marginally lean at WOT and others that run WAY rich. You need to know what your car's A/F ratio is. The dyno run on my car cost me $70. Cheap insurance if you ask me.............Paul

Thank you for saving my thread!!

Why is Nitrous worse for engine wear than a turbo? (or is it?) I know nothing about turbos ... are you able to adjust the amount of boost, akin to getting bigger jets for Nitrous?

Wear is probably very similar.

You can adjust boost on a turbo which is like changing jets on nitrous.

As far as the bad stuff goes, nitrous could have a solenoid fail which is like having a wastegate fail on a turbo system.

I've had a turbo vehicle and knew that the engine was designed and expected to handle the turbo. My concern is for the little 2.8 that wasn't expected to handle the nitrous. I'm still thinking.........

Is anyone going to have a NOS equipped vehicle at the Dells Run in June / '05?

Thanks for the input, everyone.....

Mark

So, to sum things up at this point ...

If I run a 50# shot for about 8 secs 5 times a week, I can get about 2 months out of a $40 (10#) bottle, and probably expect not too much additional wear (assuming the rep commenting on the 4cyl was right and the 2.8 would wear about the same ...) This would basically be using the shots to get on the freeway once per day, which with all the traffic around here, is probably about right. To play it safe, do not increase above 50# jets, do a dyno to check the WOT air/fuel ratio, get a bottle heater and arming switch, and maintain that valve (so it doesn't stick.) Sounds like cheap fun for $20/month.

Thanks for all the input.

I heard that turbo can be hard on your engine in a bigway.... With a turbo You will need more oil changes and more soo then ever..... From what I heard since it does use your engine oil for it's lubrication. Oil changes is about $20bucks each change.

Using turbo is expensive unless your good at fabrication...... But cost wise I think nos will yeild cheaper proformance.

Other downfalls in turbo is turbo lag But the power is there at no cost. But is always hard on the engine everytime you drive it.... With nos it only gets hard if you juice it.

both have good things and bad things.

I wonder if one could run both

[This message has been edited by 86fieroEarl (edited 10-20-2004).]

they are both hard on an engine... unless it was deisgned for it from the factory. you could run a 50 shot easily w/out problems.

Well, seeing as there is so much free information regarding nitrous here, I just have to ask a question as to what you guys think I should run. I'm building my 2.8 up with forged pistons, moly rings, lumpy cam, new valvegear, and so forth. I'm thinking I'm going to nab close to 200 horse out of it (dang intake being all restrictive) and I know I'm going to hit it with nitrous. I just don't know how much! I know it will be able to take more than a stock engine, but how far can I go... I'll probably use the nitrous 3 or 4 times a week, (I like to race...) and I was thinking a 100 shot wet kit. More? Less? I don't know! Any opinions? Thanks guys.
