SR & Nitrous

[Redline240]

Has anyone experimented with Nitrous on their SR? If so, what kit did you use, and how did you find the setup?

[KRPSICHI3]

I think they did on one of those Honda s2000's on the Fast and the Furious? (LOL) I don't recommend it.

:ylsuper

[Redline240]

Why not, and nice sig....

[BuudWeizErr]

There is somebody here that is running I think 20 psi and a 55 shot, I'm sure he'll see this thread.

One of my friends, who has an SR just put a 50 shot on his so that he could beat a GT Mustang with a lot of bolt ons and I think a 100 shot... needless to say he spanked the Mustang, but it didn't fry his engine...

be that as it may, I still don't like nitrous.

[bp2ooo]

nitrous is extremely addictive, next to impossible to predict outcome, and really expensive. It does make huge improvements, but ive already messed up my ka with a direct port 100 shot setup. I think i just fryed my valves, but there prolly more wrong. Ahh, just a good excuse to get an sr anyways, but i wont put nitrous on sr. I guess ive just had bad luck with it.

[Redline240]

Well i won't be getting an SR until next winter, but i wanna compete with my car this summer using the KA....but i don't wanna spend too much on the KA since it's gonna be taken out, so i was hoping that i could use the same setup on the SR but nothing more than a 50 shot.....so i was hoping that it's been done a few times so i can find out how people are finding it...

theres nothing wrong with putting nitrous on any car, let alone a SR, i have no idea where these previous comments are coming from.

Maybe do a little research, nitrous is beneficial to ANY application when tuned correctly, it just so happens to be 40% of people have no idea what they are doing, and cause themselves problems. But dont let anyone tell you its a "bad idea"....Just know what your doing, or have a professional shop install and tune your car.

[SRdS14]

i don't plan on putting nitrous on my sr...but (if i ever) i would use a sneaky pete for off the line purposes. nothing huge. ANYWAYS, i'm responding to redlines comment for n2o on the k-motor. i put a 75 shot zex kit on my ka before i got my sr BONE STOCK. i shot it all the time. never hurt a thing. if that is what u wanna do, then go ahead. i highly doubt it'll ruin ur motor. unless your girlfriend gets mad at you when ur sittin at a light and hits the switch when ur not goin anywhere. i'm glad i caught her ***.

[DonDonati88]

Your g/f did that to you? LOL

[DonDonati88]

Also, say I have a pretty stock s13 sr and add say 75 shot of NOS, what times should I be looking at? Low 13's?? As far as tuning goes, do you recommend just bigger injectors? Or anything else? If I need 550cc, might as well put that 1k toward a turbo upgrade, right?

[I H8 UR DSM]

if you have a stock Sr, and shoot a 75, you will probrobly detonate....thats why i said tuning is key, fuel, ecu ect etc etc...

[I H8 UR DSM]

oh, sorry....yes, fuel, intercooler, ecu tuning, etc.

[I H8 UR DSM]

and guages to monitor your engine : )

[DonDonati88]

ok so gauges, fmic, and ecu tuning. thnx

Dont you get tired of answering all these questions on this forum everyday?

[I H8 UR DSM]

sometimes, but i donate my time to try to help out : ) but sometimes my patience wear thin : )

[Redline240]

I don't think i'd want to use nitrous with the stock T25 since turbo lag wouldn't be much of a porblem, but if i was to use a T4 or GT30 or something then why not use it for the launch and get that thing spooling.....i would probaly think about using a 35 shot or something with the stock T25 but only if all my tuning was up to par....i'd like to push the limits of the engine before i get a new turbo so why not use nitrous....

[KRPSICHI3]

I suppose anything done in moderation is ok. I would just be very careful.

[DonDonati88]

Listen everyone: Nitrous is OK with low mileage engines and are being well taken care of. So stop freaking, and when you get Nitrous make sure you have a FMIC, larger injectors, ecu tuning, etc to "handle" everything. If you do this Nitrous is FINE....hell it's a beautiful thing....just imagine running low 13's and beating SVT cobras..wheew that would be sweet.

[DonDonati88]

Word of caution, by the time you spend the $1500 or more to get your 75 shot tuned right so you wont blow anything up you could have spent that money on a turbo upgrade (saved a little more) and gotten REAL HP. So nitrous is kinda a waste of money. But hell, if you got money you got money. Imagine a turbo upgrade...that sits u at 390hp (enjuku kit), AND a 75 shot of NOS...damn that would be a 12 sec car if not 11's...and you'd prolly have to get 770 cc injectors though...A LOT OF $$$

[BuudWeizErr]

I would hope that a turbo kit that nets just shy of 400HP plus a 75 shot would put you into at least into a high 10. With some tuning and high octane fuel, you should be putting down almost 500HP. I mean, didn't Ken run a high 12 on his T25? That is a very respectable number for a hair dryer.

[Dori Dori]

Nitrous and boost are a wonderful thing. Near stock WRX's were in the low 13's and high 12's w/ nitrous + a boost controller. Fun times.

i get what your saying, but a turbo upgrade isn't much good to me until i get the SR in a year. However Nitrous would be fun on my KA and when i get the SR it will help me get into the mid or low 12's before i upgrade the turbo.... :pface so i think it's worth it...but to each his own, to me nitrous isn't cheating cause you don't need all that power as a everday driver which is why many people don't run near as much boost on the street as on the strip....and if nitrous is cheating, is alcohal injection cheating as well? i'll never understand the reasoning behind that theory....

[BuudWeizErr]

It's not so much cheating unless you are racing somebody who doesn't say they have nitrous like if two mostly stock civics were going at it and one was on the bottle, but didn't say anything about it. I could see it being construed as cheating. And the other thing. SO MANY people just put nitrous on their mostly stock cars and don't tune, don't know a thing about tuning, they just squeeze. That's why it gets a bad name and a bad rep.

[I H8 UR DSM]

id run a small shot 50-75 if i had extra money laying around, or someone wants to donate a bottle and nozzles : )

[Cyberkreig]

What kinda setup would you run? Direct Injection? (I dunno anything about the different setups). After reading through the Overboost article on SEMA and seeing Nitrous Express's new N-Tercooler. I'm thinkin maybe the bottle wouldnt be too bad, especialy in a dual use role like that!

[pampadori]

i have a 55shot zex kit on my sr. i'm using the jwt ecu which is rich enough to begin with. with the n2o on my fuel pressure goes up another 15-20psi. i still think i'm too rich with my setup. i've spent about 4 bottles so far. $30 a piece to fill. the difference it makes on my spool up is amazing. i start squeezing at 3000 rpm and boost hits hard with the n20 immediately. without i have to wait till about 4000 for the kick in the pants. i also have a friend with a talon with a 16g upgrade and he runs a 55shot too. zex also. he doesn't have all the misfire problems i have at the moment, but he certainly does see a big difference even without a laggy turbo. get a nx wet kit if you have the extra money. or zex, but wet is better when you are making big power.shaun

[Redline240]

Are you running the stock T25? and yeah i agree on the NX wet kit, that's what i'm planning on....not cheap though....

[777aaron]

If you're not cheating,then you're not trying hard enough to win.

[pampadori]

Are you running the stock T25? and yeah i agree on the NX wet kit, that's what i'm planning on....not cheap though....

no i'm using a k3t sard upgrade. same turbo as the blitz upgrades. i got the nitrous for the lag and for the intimidation of purging at the starting line! i'm tacky.with the t25, i wouldn't spray unless i had bigger injectors or unless it was a wet kit.shaun

[DonDonati88]

So with the t25 if I got S15 injectors (480cc), got an ECU reprogram (adds 25 hp) and added a 50 shot, would that be safe?
