zex dry kit...need a few answers

[uncle_louie83]

ok i might be picking up a zex dry nitrous kit from a buddy for dirt cheap. Right now i have a walbro fuel pump and the rest of the fuel system is stock. can i run a 50 shot on stock injectors or could i run a 65 shot even? how high of shot can i go safely on stock injectors with the stock computer. I have an apexi SAFC. Should i make it run extra fuel like add 2 or 3% more fuel from the safc for extra measure? I need some answers mostly because ive only used a wet kit before and not into the whole dry kit as much

thanks in advnce

From my experiences, you'll need no ecu or injector upgrades, not the use of an safc, especially since you have a Walbro to push more fuel. You're not going to run lean.

I ran a 50 shot, same kit. All I did to prep was Seafoam the motor(new 02 sensor, oil, filter) and a step colder than stock NGK. One issue with running nitrous though is that you NEED higher octane, plus the step colder plugs to burn the premium. Which....isn't cheap at the moment. NEVER spray on mid or regular...unless you like pinging.

But anyway, I ran mine up to 75 with no issues, and I lacked a Walbro. So in my amateur opinion, you're golden.

thanks for the valueble info. i was thinking the other day that i should be ok with up to a 75 shot...i wouldnt see why i wouldnt be able to cause i see people running 8 to 10 psi of boost on stock injectors with a walbro pump.

[uncle_louie83]

and what number of plugs were they.???

ummm....crap. NGK are opposite of every other spark plug as far as heat index (ups down, downs up) I want to say bkr5e the irridiums. Check to be sure.
