I have a b18b1 swapped into my 95 civic and i hooked up a Nitrous Express system. I am running 35 shot but want to up it to 50 shot, will this be to much for the stock internals?

 

That should be just fine.

Come on people back me up!

 

I'd back the timing off and richen the mixture a bit. You should be fine though.

 

ive got your back! it'll do just fine with a 50 shot!

 

You changed your plugs, right?? These are what you want to run: ngk bkr7e
Do NOT use platinum or Zex plugs. Way too many problems reported and witnessed. Like melted electrodes, insulators, etc.

 

50 shot is fine, go 70 with an ignition and maybe a fuel filter

 

Hopefully he is already running a fuel filter.

 

Spraying 75 to mine with Zex plugs and retarded timing....no probs yet, but motor is mad strong in high RPMs already...

 

you should be more than safe..

with that engine, i would venture to say 70 would be pretty safe without retarding timing, as long as u are using at least 93 octane gas or higher..

might wanna check out colder plugs tho, and ignition setup if you get really into the n02

good luck with ur setup!,

Thank you!

 

I was running a 50 shot with nx and no problems at all. Stock timing with 2 step colder plugs and went tru a few bottles and my b18a took it perfectly. Even nx says that you don't need anything to change with their stage 1 efi (35-50-75 shot) But i'd bump the timing back 2 or 4 degrees with the 75 shot.

happy spraying, nx makes good kit

 

tuning is key!

 

 

A 50 shot is like buying a lap dance instead of a bj, a tease. I had a 70 shot in a sohc and never had a problem. A 50 shot of laughing gas would make me do just that, laugh at you. Step up to at least 70, dont be a *****. Your engine can hold 100 so what is 70 gonna hurt?

 

I was running ZEX 75 shot on my b16a1 CRX all summer last year, went through about 8 bottles. Not 1 problem, actually i melted an electrode once. I was running 4 degrees retarded and 1 stage colder plugs. The only reason i melted it was because i was NECK AND NECK with a 4wd turbo&nitrous DSM, we both went to top speed in 5th on the juice. he beat me by about 2 feet.

 

hahaha same here! I was racing my friend's b16 hatch and i was winning the race until i melted a plug (LS tranny, top 4th)...scared the **** out of me!

 

ive ran 100 shot several times and didnt have a problem.. but i feel alot safer with the 75 shot and 2 degrees retard.. runs all day long ..

 

From what I understand, NOT all the time, rule of thumb is take your engine's HP, divide it by two (or half, whichever suits you) and you should be able to do that number with stock internals.

I don't know if you can give a 500HP Viper a 250 shot of Nitro, but hey, someone probably does.
