nitrous on nismo

LEGA-Z

Just installed a Nitrous kit last week... 50 shot... runs great! Just closed the gap on my stock plugs (Denso Iridiums) to .038.... Besides that no other changes. No problems at all. just dont shoot at the lower rpms, just to be safe.

I would like to see some more people go this route. if it turns out to be very reliable on the vq's, then it would be a good alternative to dropping $8k+ for fi

If you're going to run a Nitrous setup, than do it right. I would do a direct port to be safe, that way each cylinder is getting the same exact amount of N02. With a tune, you could run a 150 shot easily.

Without direct port, I wouldn't run anything over 75. Too much of a gamble.

I see your SC'ed but do you have "Direct experience" with nitrous? A direct port is the best way to go but don't believe its nesseccary or the "only" way to be safe.

With a tune you can do anything, thats a given. Just cause you run a direct port doesn't mean you won't run into issues. It just minimizes factors more.

As far as a 75 shot being too big, is this by first hand knowledge? Because using the stock map and spraying a 100 shot. My datalogs show that my AFR is running rich at a 10.xx according to Randy at UpRev.

I stated it was a gamble... and it is.
Anytime you run Nitrous through the intake you don't know how much each cylinder is getting since the stock intake manifold isn't meant to run a gas or liquid through it. I don't have personal experience, BUT other people have, including someone that blew their motor for me to learn from their mistakes.

You also didn't read the part that said, "I wouldn't run anything over..." That's my personal opinion, take it with a grain of salt.

Also, air fuel isn't the only factor in tuning. You can run rich as hell and still detonate.

I was the first person (at least on this forum) to hook nitrous on a 370z. Bought the car in 09, 2 months later i hooked nitrous up, 6 months later, sold the car...lol.

Really? I thought that you bought it for the car and never hooked it up before you sold it. I remember reading your post. Anyways, the only person I ever saw post a thread about nitrous before I got mine was a guy with a 40th Z.

How's the X treating you? I would have gotten an X if a dealership here carried them.

i had it fully hooked up and able to spray. Was just waiting for a tune, then i decided to sell the car. But i was defently the first to hook it up because it took alot of research and mainly going off the 350z's kit to see what i needed since i bought a single fogger universal kit.

The X? well, lets say she is having some work done due to this...





My tuner advanced the intake valve timing to much and didnt touch the exhaust side. To much air/back pressure, snapped the exhaust valve which jammed in the head sideways and chewed up the #1 piston.

Sold my FP Red turbo to buy a bigger FP Black turbo, but changed my mind. So did the guy that bought my turbo so im buying it back, as well as i just orderd a few parts, along with a new head that has been hot tanked and ported with +1mm valves, springs, cams. Hoping to have it back on the road by the summer.

As for now im driving a 03 cavalier and **** do i miss the Evo. Cavalier doesnt have power windows or locks, no cruise control. CD player doesnt work, not a 4 door. And its not AWD

Damn sorry to see the issues. Such a costly mistake. On a positive note, now you can make some serious power on a built motor.

I was tuned by a guy down in the states that does e-tuning. Seemed like a good guy at first but few of his methods made me nervous so i questioned a few things. After that it was pretty smooth sailing. Once the engine popped i had no idea why it happend. I was at the drag strip that night for the first time on this setup. Wasnt hitting anywheres near the numbers i should have been. Stock i ran 13.5@100. DP, TP and air filter i ran 13.2@103. Evo's with boltons are mid 12's. So i should have been in the 11's for sure but i was only hitting 12.3@112 (hitting rev limit in 4th about 75-60ft before the finish. My last run my CEL came on. Checked everything out and it looked fine. None the less i told my buddies i was taking off to see what was wrong.

Half way home the engine died and wouldnt fire up. So i called a tow truck, asked for a flat bed and they sent a normal truck. Long story short about that, the tow truck driver didnt listen to me and cooked my tcase. They refuse to pay for the damage and i dont have the money or time to waste going to court over $1500.

So i thought the damage to the engine was from me. One of the other tuners on the evo forums asked to see my tune. Sent it to him and he confirmed that my tuner ****** up. At the same time there was a thread on the forum talking about my tuner. The tuner that looked over my tune, posted up what he found and i posted my thoughts on it. My tuner then emailed me asking me to call him. First of all, im in Canada and im not paying long distant fee's to call him when emails work just as good. Second of all, i was in the field with the army where cell reception was poor. I told him this and told him if he wants to discuss anything it can be over email. He denied blowing my engine up and i havent heard a word from him since.

Since then i was contacted by another Evo owner in Canada with the same exact issue. Motor blown, valve snapped and took the piston out. He sent his tune to the other tuner that looked at mine and our maps were nearly the same.

So the tuner refused to help with the engine and the tow company refused to pay for the damage they caused to my tcase. So its going to be about $5000-6000 in parts for my engine, $1000-1500 labour to rebuild the engine and $1500 to rebuild the tcase.
