I ordered a zex kit and civic type r camshafts for my 95 gsr still in process. I was wondering what's the maximum psi shots my motor can take? What do I need to make it take a big enough shot? maybe 75 or more? i heard that 65 is average. can someone help me or give me info on what to do thanks

 

Don't know much about ZEX but I ran 75 shot of Nitrous Express on my GSR and never had trouble.

 

i would try not to go over a 75 shot ..

 

oh and the psi on the bottle should not go over 1150 and normal would be around 950psi..

 

If you must run 75...you def need 2 step colder plugs and you need to retard the timing. I wouldnt go over 75 on a dry kit...when youre getting that high you might want to consider a direct port setup and more extensive fuel and ignition modifications.

Stick with 65.

shots are not measured in PSI. psi refers to bottle pressure. When someone says a 65 shot that means a shot worth producing around 65 horsepower ..not 65 psi as you might have been thinking.

 

Me and my integra like to do shots of Jagermeister together.

I would stay at 65, especially if its dry, which i beleive it is. Redlinegsr has been runnign the zex kit with no probs for about a year now, and pulling soem respectable times.

 

i have a 01 gsr with CTR cams and a zex 55 shot...it just gives me a little kick, im so tempted to try the 75 shot...

 

man i have seen people running 100shots on a b18b without a prob but its all up to you the amount of risk you are willing to take...

 

I don't mean to sound like a *****, but all of these people aren't really giving you good advice. I'm guessing you don't have the kit yet, b/c the instructions give the best advice.

Both my friend and I have run the zex kit on a B18C1 with no problems. A 55 shot is normal, without colder spark plugs or retarding timing. To run a 65 you need colder plugs and retard the timing -2. To run a 75 you need colder plugs and retard the timing -4 degrees.

Yes, people do run 100 shots on stock motors....but not for long. If you want to run anything over 75 shot you are going to want at least new rods/rings/pistons. Also, if you run over 75 you probably want a direct port nitrous system, as that will ensure you get the right amount of shot to each cylinder.

Please search and follow the instructions.

 

I just told him what Id do...Id be nervous shooting even a 55 shot without retarding the timing a degree and putting in at least one step colder plugs. Ugh Im a worrier though

 

I got it put it, i am running 55 shots rite now, will be squeezing higher when i get a new clutch!

 

i have a zex kit for sale with purge valve, 350shipped

 

thats a great offer but i have a kit already thanks

 

50 shot you should be fine. Play safe.
Don't forget to retard your timing 4 degrees or so.

 

whats the best bottle pressure to be running for a 75 shot at night........my friend had his 50 shot bottle pressure at 1300 he said it pulled hard i squeeze his car when it was at 950 felt barely nothing my skunk stage 2 feel stronger.........

 

everyone PM mintegra97 and tell him to hook up his Nitrous, he's had it in his room for like 3 months!!

 

im running nx wet 50shot best bottle pressure is between 1050-1150 i just use bkr7e plugs and replaced my clutch n flywheel

 

I'm running b18b1. 440cc at 55 psiWet fogger kit 80 hp shot in now and a 100 also on stand by depending how it does -8 pulled for timing for 3rd and 4th gear
what step plugs should I run one or two step colder please from someone who has experience or a kit in there car thank u guys n girls

 

super old thread. But go to a 8 heat range. I’m not sure if these engines use projected tip plugs from the factory or non projected but a nitrous engine really needs a non projected plug so it doesn’t act like a glow plug. Start low on the timing and work up. Until it stops gaining as much power with each additional degree then take another out and you should be good. After each pull kill the engine immediately and check the plugs. Idle time will wash the fuel ring, even a little
