[Oxford S2K]

So i had a integra that was stock motor but everything around it was aftermarket. Now i ran a 100 shot of nos on it from 120,000 to 200,000km and i never had a problem with the motor. Has anyone ran nos on the s2k yet and if so what has the shot been like and is it really killing the motor.

[import2nr]

any nitrous shot through any engine is killing it slowly/beatin' the sh!t outta it. I'm installing nitrous on my s2000 but I dont plan on using it for much of anything but purging. The s2k doesnt really need nos anyway. if you dont wanna kill an engine but still wanna use nitrous, id recomend a NOS programable controller, that should realease a certain amount of nitrous over time to give better acceleration, & last, etc.

IIRC an owner at S2KI initially ran NOS on his motor, and then went on for 100K supercharged miles on the same engine.

A correctly set-up Nitrous Oxide system should not harm the engine. The problem with Nitrous (and turbos to some degree) is that people try to install a cheap system or find it too easy to increase the power without looking at the whole system. Eg I'll just up the boost on my turbo without worrying about tuning.

A wet NOS kit is better than a dry kit. Make sure your fuel pump can handle it. You may want a bottle warmer + purge system. Engine management for tuning. WOT switch...etc.

As you already have what seems to be a reliable system on a previous car, I guess you are in a better position to comment than I am.

Also keep in mind that in many places it is illegal to have nitrous fitted to a car on the street. Some places will allow you to drive with the kit installed as long as the bottle is not connected.

Also keep in mind the fact that many people have crashed their S2000s by losing the backend and spinning. Hitting Vtec in a corner is bad, activating NOS while turning is even worse. Even on a straight it is possible to lose grip in the rear tyres (esp in the wet).

new to the site... hows everyone.. feels good to see fellow S-2-thousand-ers...lol, question; on a hundred shot of nos what kind of 1/4 mile numbers does anyone think the S 2 grand (<---my own labeling) can put down..?

[s2000isu]

not fast enough to make it worth doing that to the engine. I suppose a good nitrous setup with multiple stage a seperate fuel pump and so on can be safe but I dunno seen to many motors go boom. I think gomarlins might be able to give you an idea of what a 100 shot might be able to do about since he has 100 more whp then stock. All this talk about nitrous on the s2000 is scaring me AND i TRIED TO TOW A F-250 WITH IT so what does that tell you?

[gomarlins3]

NOS is out of my knowledge range, sorry.

[s2000isu]

i absolutely refuse to say nos since im about as anti ricer as you can get. I just meant since you have 300 hp you could give a very very very very ruff idea of what a s with a 100 shot could do down the track have you run yours?

[Java Junky]

Amen Matt.
Especially that last part about the mixin' of any kind'a sudden change in traction at the rear wheels durin' maneuvers.
I've always found it better to admire the roadside foliage from afar. Pickin' clumps'a sod n' 'possums out'a the damaged nose almost always winds up costin' money r' worse.
Be well.

Haven't run mine down the 1/4 mile yet. Not sure if I am. If I do, I will have a poor 60' due to my lack of launching the car.

[Jiggged]

SOo would you guys suggest that its more worth the dollars and hp to just go
SC over NOz....

[Jiggged]

I haven't run mine... but i have this All American muscle head talking more than i wanna hear... he has a GTO, i know Supercharging would be the best route to shut him up, but i dont want to drop the 6grand and then have a hard time when i want to sell it... any advice on the whole situation

[s2000isu]

what year gto and whats done to it?

[Jiggged]

should be an 05... not a 100% sure... but i do know he put a new exhaust on it but thats about it

[gomarlins3]

Meet him at an autoX course, then ask to race him.

Pretty simple really. There's a fairly strong market out there for used SC kits. In fact I have no less than 2 people still waiting for me to sell mine to them when I go to sell the car.

Anyway, when it's time to sell the car, you remove the SC and all your other mods and get rid of the car. The only traces that the SC was ever there are a slight deformation of a cross beam under the airbox (completely covered by the airbox, you could probably bend that sheet metal back if you really wanted to) and some heatshrink tubing or electrical tape where you remade the connections for the voltage clamp. Easy peasy.

Look at it this way:
Say your car was worth 15K on the used market. Having a S/C on there will make it worth anywhere from 2K LESS (because MOST used car buyers are going to be nervous that it was abused) to maybe 2K more. But, it'll take a while to find the right buyer. As a trade-in, I'm sure you won't get a cent more than BB even with mods, the dealers know what you know.

So, sell the car for 15K, you can easily sell the S/C for half of what you paid for it on S2ki.com or ebay (many peeps have sold their setups for 2/3 of new or even more).

As far as performance. I refuse to abuse my clutch or diff, so my best ET was 13.7 SCd. More importantly, however, is a trap of 108 which I can get consistently. I've seen some claimed ETs of 13.3 with a S/C but that trap seems to be about right. So, basically, it's about as fast as a stock M3. In other words, slow.

[s2000isu]

thats weird 300 whp in a car our weight should do 12's all day long

[gomarlins3]

Without a launch, a low 13 doesn't sound bad.

[s2000isu]

i am just looking at power to weight ratio and people get 2.0 60 foots on regular old tires all the time. i think with some nicer tires you could do a 1.9 -1.8 and with that kinda 60 foot with 300 whp you should be able to do pretty consistant 12's

[Halo]

What you are not considering is that hp is VERY peaky. Yes, close to 300whp for an instant before redline. Anyway, "if" you can rip crazy 60' times, you can get all kinds of great ETs.

However, the trap tells you how fast the car is on the road. 108ish is nothing to sneeze at, it's just not that fast.

[Jiggged]

HALO<<<<<<<

Thanks that was actually my first thought just havent decided on actually doing that.. can any damage be done to a SC if the person who had it before me was running it to hard all the time?

[Halo]

Like some wise person once said it's not how hard you run it, but how you run it hard.

As long as it was sufficiently warmed up and the oil (which lubes and cools the blower) was changed regularly, just keeping it in boost isn't going to break the thing. But, like any machine with moving parts, it will wear eventually. Have not heard about Comptech blowers themselves failing.

[Java Junky]

Jigged;
If all you wanna do is shame the offensive goat person n' the 6 Gs for SC is too high . . why not add insult to injury n' jus' go pick up a fairly solid but ratty-lookin' 5.0 Mustang for 2 r' 3 Gs n' apply said shame with a trowel?
It'll also give you somethin' to flog whenever the mood to drop the hammer at stoplights overcomes you.
Be well.

i was thinking of putting on a zex elecronic wet kit with about a 55 shot cause i dont have enough for a sc yet. Should i be worried about fuel starvtion or preignition?

[ElBabyBoricua]

i

[ElBabyBoricua]

ive been runing 100 shot for over a year every week at the track w no problems, best time so far 12.8 @109 on street tires 18inch wheels, only upgraded fuel pump, exhaust, intake and headers

[TheSoundMan21]

+1 for what Java said. Dont flog the poor S2K off the line its a track car not a drag car. Thats just me (if I do race its in the wet which is fun cause I just pull of the line slow and out drive the opposition)

[s2000isu]

I remember this thread almost 2 years old now. Turns out I was right about the s running 12's with a sc

[killabee]

man this is a old thread. well to stay on topic you can run nos If you have It properly installed as with anything. But would I run nos,No.
