hey guys i'm new around here, i got a nissan fairlady Z 2004 (the japan version of the 350z).

i'm installing a zex kit 82220 and i want to shot more than 100 shot
(like 120). Is it possible that i only buy bigger jest or should i also buy bigger solenoids? because the manual tells maximum of the kit is 100 shot.

What jets did you use for a 150 shot? Did you retard the timing or are you running stock timing? I've been on the fence about going over 100.

150shot is the max the solenoids inside the box can handle.

I run -4 degrees of timing

Thanks, CL. What jets did you run on the 150 shot? Did you trial and error it until you got the right ratios or was it recommended by Zex?

I did alot of searching on the forum. You have to decide on what size shot u want to run. 150 at the wheels or at the crank. Zex measures at the crank. NOS brand measures at the wheels. The 350Z has 51psi base fuel pressure (higher than most cars). I used a calculator i found. I have not dynoed yet to see where my AF ratio is at yet. I run .057 and .033, which is about a 145hp shot

CLyons0203, what are you using to pull timing to -4?


Also, regardless of what's recommended as jet sizes, I suggest you check the AFR just in case.
