Want to use a high nitrous shot 125-200 shot and I'm thinking a thicker headgasket would help with the safety barrier anyone else think this is a good idea??? Some of you guys are getting 500-600 whp on thicker headgaskets why can the s2000 take a 200 shot of nitrous on a thicker headgasket?

Will be using 93 octane pump gas, zex direct port nitrous setup, with all the nitrous accesories aka window switch,bottle heater etc, and AEM EMS to tune.

 

I dont know a whole lot about nitrous but what I do know is that it adds oxygen to burn to the charge and cools the cylinders also. What I'm getting at is, I dont think lowering the engine compression is going to have any benefits as it does with boost. With FI, you are adding compressed air (boost) into the engine, not necessarily more oxygen to burn and with this, lowering the engine compression helps with the detonation threshold but I dont think it will help at all with nitrous and may actually hinder what youre trying to do.

If someone knows more about nitrous and I'm getting it wrong, please feel free to correct me.

 

I would only go up to 200 shot if you were running a direct port setup. Lower compression or not.

 

And what do you suppose compressed air contains? FI and nitrous are both methods of delivering more oxygen to the motor

 

Like in the PM, I don't think its gonna be worth it.

Aside from that, I'm keeping my mouth shut in here.

 

well, i wanna see this happen. 200 shot progressive, maybe a dual stage, 100 up front and and second hit of another 100.

you would go thru nitrous very fast! would get expensive quick. but, would move.

i dont think lowering compression is as big a deal with nitrous as FI, but can help to a certain degree. when i read about purpose built niutrous motors they are in the 10:1 range, where as purpose built FI motor could be in the 9:1 range.

its a touch call, cuase the effect could be a blown motor. remember too the dynamic compression of our motor is much much lower in vtec. being that, just spray the ****er and see what happens! make sure you have stand alone and bigger injectors, as well as a walbro pump...etc.

 

I would think that a thicker headgasket would help but a 3mm might be over doing it. Just remeber anything that would help against detonation is always a good thing.

 

nitrous loves high compression

 

Just get the car dynod and watch the AFR's and adjust the jetting accordingly. With that kind of shot your deff gonna wanna run dual stage(id say 75 first stage,and then the rest progressive time based for the second) and a progressive controller. Check out dynotunenitrous.com for cheap parts. That car is gonna movveeeeeeeee. My 75 shot on my SR20DE sentra was sketchy, no prob lighting up the tires in 2nd and 3rd, Falken allseasons but still lol.

 

Yes the compressed air has more oxygen in it, but with nitrous, you dont get the compressed air like in FI, you get tighter controlled oxygen molecules and thus dont need the lowered compression engine as with FI. That was my point and this is the way I understand it.
