Whats the Proper Gap I should be using ??

Im using the One Step Colder Copper plugs from NGK
6's

V2 Blower
3.125 Pulley
MEVI
JWT-ECU (7200)
370cc Injectors
Z32-MAF

Do you think I should running 2 step colder plugs ?

 

I have heard alot of conflicting things about gapping. I am at .034ish on one step colder and have no problems with spark blow out.

 

I have mine at .036 and runs great. 1 step colder. I did have them at .034 which was too low for me. I was getting hesitation near redline in 1st gear. I have 3.125. Hey did you notice a big/good difference when you got your 370's and jwt in ( workin good) . Was there a noticable power gain? After breaks thats my next hurdle
I don't think you should be running 2 step colder. my opinion

 

Use the widest gap you can without blowing out the spark. What's a 3.125 is that 10psi? I'd say you are probably safe with 1 step colder at anything under 400whp or so. Above that you might want to think about going to 2 step.

 

Not much of a HUGE difference but i havent really drivin the car all that much yet. Im alot happier running the 370's and the JWT knowing im not running at 90+ psi of fuel pressure and knowing that im at a closer tune now..

Next will be an SAFC, and a tune

Double checking - Im going to need a 96 se 5 spd ecu correct? Im 99 cali. For the jwt s/c ecu. I thought I would go with a 7500 rpm limiter just to have the extra if I want it. It sux not being able to go over 4k without dumping the fuel.
