As much as I didn't want to create a thread I must admit that my searches came up with garbage and very little information. I was extremely shocked by the lack of knowledge on the topic of nitrous alone or just the amount of false information followed by the word 'NOS'.

Anyways, I am simply attempting to start a topic that will hopefully bring out some good information on how the s2000 reacts to nitrous; a 'Tips and Tricks' thread if you may. If such a topic already exists feel free to point me in its direction.

For someone considering a nitrous application what are some points that they should look into, i.e. fuel pump upgrades, timing and timing control, nozzle positions on the F series manifold, and other recommendations.

What shots have we seen on a stock internals engine?
What the estimated power limit for the stock fuel pump?
At what points should you start to retard timing and at what rate?
Is the stock fuel line (from the pump to the rail) capable of feeding the engine and a direct port setup under a 150 shot?

What has been your experience running nitrous on your S2000 and what suggestions do you have?

I am considering a direct port system (NX; lightning stage 6 solenoids, piranha nozzles, 12lb composite bottle, and window switched with throttle activation) hence my reason for starting this thread.

(this is not my first nitrous excursion; I've ran both single-wet and direct port setups in the past. This thread is simply to get an understanding of how nitrous and the S2000 interact)

I thank anyone willing to contribute useful information to this thread.

 

there's a kit for sale in the for sale section. ask the guy selling it maybe.

 

From what i've seen a 75 shot seems to be ok on the internals on this car if done correctly.

 

I think nitrous is the best addition to an S2000. Cheap easy way to make the car quick. I havent installed or driven a s2000 with nitrous but, i would assume its the same as anyother car. I would think the car could hold a 100 wet shot easily. That is with a fuel pump and colder plugs but a 75 should be safe. I would maybe consider a way of tunning it with nitrous? if possible because on a car with a distributor you would retard the timing a little for nitrous. I also know that most people spray 50% of the cars power. BTW if anyone calls NITROUS "NOS" they need to watch Fast and Furious another 100 times...

Also i would gueess after a while the clutch would take a beating but, i am not really sure how much hspw a oem clutch can take?

 

not quite the information I was looking for and having not owned an s2000 with a 100 shot, merely guessing that it will hold it, doesn't help me much.
the stock clutch disc is decent but the pressure plate is weak, a stronger unit will more then likely be required to hold the extra power.
there are plenty of ways to retard timing on a car with individual coil packs but I am looking for personal experience.
I can't justify that most people spray 50% of what their car is making as thats rarely the deciding factor when someone is setting up a system. when I was building my direct port system for my srt-4 (neon) it was strictly what was streetable (spraying a 200 shot would be useless on a fwd car with street tires).
rarely will you tune a nitrous setup outside of the jets unless you were adjusting activation points or a progressive setup. I can imagine running an aem ems and having it automatically retard the timing on specific points during nitrous activation.

I appreciate your effort but I am looking to hear more from those with experience on topic and the s2000.

 

Try to look up Italianbucwheat or something (can't remember name exactly) I know he's had nitrous for forever. Also, customcamry has been spraying a 75 shot for quite awhile.

 

Modifry also ran nitrous for a while before going FI. In fact, his Redline Shift Beeper has a funciton that can be used to gate nitrous on the S. If Modifry doesn't chime in, you should consider sending him a PM. At the very least you'll want a shift beeper and I strongly recommend that you consider the Modifry unit, as it will also gate your nitrous, and give you a valet function, peak RPM memory, and so on, in a package that weighs only an ounce or so.

If I remember correctly, Modifry said that he changed over to FI because he got tired of refilling the bottles.

 

im interested in this too.

i had a dry shot on a hatch 5-6 years ago, but if was a 2000 hatch not a high performance roadster.

bump for useful info.

 

I haven't been able to find much useful info and hope this thread turns out some useful information as well. As you can tell by my sig, I'm interested as well.

 

i think that if i do spay, i want to go for a wet shot, most likely a 75 shot.
