alright I have a big grudge street race comming up and me and my buddy are hooking up a zex kit with 75 jets (50rwhp) and i want to know what is needed to spray this....i have teh tr-55 plugs do i really need to swap plugs ? what about timing ? I will be running 93 octane and thats what my cars tuned for...

Also i have an SS4000 stall and full bolt ons will i have to worry about this small of a shot hurting anything when i go back to all motor i will only be spraying it about 4 passes.

 

Swap plugs, find out what your max wot timing is.

 

Swap the plugs and from what I have always been told for every 50 shot of nitrous 2degrees of timing should be pulled.

Is this a wet or dry kit? I'm quite unfamiliar with Zex.

 

this is a wet zex kit, 50 to the rear wheels....i will only be spraying it 4 times for a grudge race ....was told i didnt have to change anything, someone is gonna be pissed when i put 5 cars on them and they have 100 more horse

 

Don't change anything then. I mean someone told you that you didn't have to then you should be good.

Someone is gonna be pissed when their motor blows.

 

I wouldn't try to just 'toss' a wet kit on. You need a way of regulating all the variables, and you haven't even thought about those yet. If you have big enough injectors, go with a dry hit. Much less to worry about, I wouldn't even touch the tune, just some good plugs should get you by for 1 race on that small of a hit.

 

for a 50 shot i would touch anything.. At

 

I posted the right plug to run. you could get by with a tr6 at the minimum... but a non projected tip plug is the correct plug for nitrous. Imo you need to do more research here in the nitrous section before you let it eat!! Even on a 50shot those tr55's are going to turn into glow plugs... wich can cause big problems depending on how far off the tune is! Anyways it's your motor, do as you please.

 

Change to a tr6, you will be sorry by the third in if you don't.. I have a friend that thought he could get by also. Haha
Other than that, don't worry about it as long as your tune was already on.. anything over a 75 shot is.where you need to start changing more things.
If you have a way to pull a few degrees I would.

 

if i do it i will change plugs and only run a 50 shot, thanks for the help

 

tr6s and let her eat
