Good afternoon everybody, im a noob when it comes to nitrous but old school when it comes to racing and i need some help. I have read all 45 pages from this thread and more from other web sites and the old thread in 05 about the nittrous but still have some questions. I have a:

stock jdm b18c5 in a 91ef si
cometic turbo/nitrous head gasket
arp studs
edlebrock intake, itr tb, aem fpr, aem fuel rail
kamakazi headers (i believe thats how u spell it) sorry Lol!
thermo research 2.5 inch catback exhaust
walbro 255 pump
msd inline fuel pump #2225
MSD #6350 Digital-SCI Plus Ignition Control
Ecu- p28 tuned with crome program
jdm type r tranny
fidanza light weight flywheel
Act stage 3 clutch kit
Nos dp wet kit with a bottle heater.

The jets are 18 and a 24 and i did the calculation on www.robietherobot.com and it says im gonna gain 88.44 hp to the wheel but i dont know if thats a 30-50 shot that i have. My question is being that this is my first time using nitrous is this shot 2 small for the setup i have? Could i go up way more being that im not into street racing (that was back in the days in hunts point with my rotary toyota 4.56 8 ford rear ) and the nitrous will only be used in the track so im not gonna be beating on the car in the street. Im planning on getting it tuned with c16 cuz thats what im gonna be using in the track. Being that the motor has stock internals could i go up more on the shot?

Thank u for taking your time to read my post and if u could help assist i would really appreciate it. Thanks.

Ed.

 

Bump. If you read this help me bump this topic. Thanks

 

People will argue this but here is a fact. On my beat *** usdm gsr that burnt more oil than gas i ran a dry 75 shot through hondata's nitrous control and it ran like a champ. On the new setup its a fresh *** stock jdm gsr on a 100 shot dry. The only issue i have is that i'm out of fuel on the stock injectors. Still no issues otherwise

These are both single nozzle setups. Ive heard more can be had on a DP setup

 

Thanks bro. Bump ^^^^ if u read this thread.

 

BUMP!!!!! Nobody else wana help me!

 

when it comes to nitrous im the king! I have sprayed a 100 shot on stock motors all day long. I had a 125 on a stock chevy corsica and kia sephia. the corsica ran 9.3@ 78mph in the 1/8 and the kia waxes 350z on the highway all day long! on a honda u have a distributor which is awesome cuz u can retard the timing! on a stock crx d16 i retarded the timing just a lil bit and sprayed a 100 shot and it run great you just need to know when to spray, i never spray under 3000rpm but i think ur question was will ur motor take the nitrous i think a 50-75 shot should be fine but call the company who has the jets cuz NOS and NX jets are different and be sure to let them know if there for a wet or dry kit and some of there sites have a jet chart to tell you what shot it is! If you have any ?'s just let me know and i'll do my best to answer them to the best of my ability!

 

i usually use the rule of thumb 1* of timing retard for every 25hp gain on spray. you can run a 100 shot on a stock GSR, run premium, retard the timing 4 degrees, and spray away. dont do long 5th gear top speed runs, try to avoid hitting rev limiter on spray, and have fun

 

Thanks you for the response. I havent had the chance to take it for tuning but i tried it with the fp at 45 and retarded the timing 4 degrees and once i hit it at 4000 rpm it started bogging so i let go quick. checked my plugs and they were white. Raised the fp to 55 retarded a bit more and the same thing. changed the plugs and the same thing. The only thing i didnt do was heat up the bottle cuz i havent had the time to purchase a bottle heater and i forgot to purchase a guage as well so i dont really know what the pressure is. But Im gonna try again this week while these two parts come in. I was told that by putting the bottle on hot water for couple of minutes it will raise up the pressure. Is that true?

 

you can heat the bottle with that prob or use a heat gun (like a highpower hair drier) or some people evne use a propain torch.

 

so what is your timing when idling at full operation temps, with service jumper jumped?
