rough idle.. wierd noise.. kinda sounds like a diesel engine sometimes.. i am hoping its just a valve spring..

 

good job

 

does your engine shake at idle.

 

yes.. but it doesn't do it when its running.. i was also wondering about motor mounts?

 

that how mine is its normal while im driving but when I come to a stop it starts shaking.

 

you are making me scared now

 

check and see how much blow bye you have by taking your oil fill cap off while your car is running mine blows out quite a bit of air.

 

explain that further to me please.. like step by step..

 

1 start car/ pop hood
2 remove oil filler cap
3 if it blows alot of air out thats not good

A little blow by is normal but on mine you can see it and it basiclly looks like the exhaust is exiting out the oil filler cap hole.

 

i will check it tommorow... thanks..

 

Youre making me nervous about installing my nitrous

 

you only live once baby.. go for it.. besides if this motor goes.. it needs to go before 100,000 .. because thats when my warranty is..

 

at least you have a warranty

 

its going to be a ***** returning to stock though and some of the service ppl know i have NOS

 

good luck hopefully its nothing major

 

thanks.. i hope so too..

 

I hope your car's okay Sprinty. I'm sure you'll have a few warranty problems with your nitrous, so just hope nothing blows. And Tilley man that really sucks. But a total build up of a new engine will be good, and since your dad is a mechanic you shouldn't have much trouble installing it. Maybe next time you guys will go with a little smaller shot? First the people with S/Cs have mad problems, now people with nitrous our blowing engines. Sadly, the "best" mods are destroying the cars they're in.

 

actually Im kind of happy it give me an excuse to upgrade. Plus its winter and wont want to drive my car so it wont be as bad Ill just have to settle for the old mazda.

 

this is the only forum that thinks wet nitrous setups are better/safer than dry setups..

 

Stop peeing in their sandbox.

 

Wet is better...I am rweally dtrunk so don't listne to me righjt now., sorry.

All of this is making me rethinking of getting NOS too.

 

I think perhaps the worst part of this is that the main offending moment seemed to happen when you were flexing your muscle at a Saturn. Heh...I personally always found it a little amusing when guys would go mod-happy on a car, and then would mostly talk about how they mobbed on some Civic or Cavalier out on the roads, cars that they would have spanked in a race anyways

 

so you're now saying dry is better?

 

Okay, this thread is getting me worried. TILLEYS99's problem was because he didn't have a window switch, so I'm not worried about that, because I plan on installing one.

But Sprite, do you know what's caused your engine problems?

 

You know i like it dry & crisp.

Maybe you should explain Phuong.

 

NOS = Your Maxima on drugs. :hungry drug addict voice: Yo, lemme get some of that bottle yo

DW

 

it started after i was running the wrong fuel jet and running way too rich on NOS.. so its my fault mainly..

 

I thought too rich would just hurt performance...it can cause engine problems too?

 

Eric don't get worried.. i am not 100% sure whats going on yet.. i will find out soon.. one other idea might be bent valve springs.. which i hear is almost impossible to do on a VQ.. so its all speculation.. don't worry..

 

Not worried, just wondering. I'm only gonna do a 50shot for now, so I can't imagine damaging the engine with that...

 

Floods the motor & fouls out spark plugs. Running too rich (not just "rich") can cause you to burn a piston ring (Or so some of teh track guys have told me).

 

On some cars it is true. Like the Lightnings & WRX come very rich from teh factory.

On cars like rx7's, they have to be tuned right. They are VERY picky about the A/F mixture. If you mod that car w/o tuning, the car runs very rough and next thing you know, you have problems.

My cousin plays wiht MKIVs, RX7's, 300ZX, Lightnings, Mustangs, & Porsche. He has to make some sense.

 

This all just sounds really bad... I haven't had any problems so far, but Ive always taken it really easy and slow...

 

Bite your tongue or knock on wood Matt!

I have only used 3 bottles and its been about 10 monts since i had teh NOS kit.

I know i ont use it much. hehe.

 

Let this be a lesson to all of you dont use NOS without a window switch. And synki I agree with you about running rich it will cause you to wash out the rings Ive heard that from this guy who has a 7 sec. tube frame Vega. I wouldnt worry about NOS hurting your motor unless your using a big shot.

 

I never had a problem with 100hp dry system. I always ran one step colder plugs and made sure the nozzle was pointer in the right direction

If I didnt get the SC I would have gone to perhaps 125hp dry.

They key with all big performance DIY modifications are to increase power levels in a controlled, claculated and conservative approach. And dont skimp on the parts.

 

Thanks for backin me up.

Tilley, good luck with yopur search and i hope you can get your max going again.

 

Hmm... this is an idea! I wont go 125 until i can actually get traction. I dont know many autos that spin through 3 gears like me.

Maybe its time for the b-pipe.

 

125 hp NOS jet
