1. i was just on the zex web site looking at their jets and they are listed by Size. i'm assuming this is the diameter not hp. which one is a 75 shot?
.032
.034
.035
.036
.038
.040
.043
.046
.052
.073
.078
.082

2. which plugs should i use?

im gonna be doing a dry shot on my built h23
(something to hold me over till i can get turbo)

i hear 75 is about the highest you can go safely dry? any ideas about going bigger without tapping the manifold?

 

.038 i believe is the 75 shot

 

anyone to confirm this?

 

go to the zex webstite and look for their tuning sheet. it has what shot is the 75 shot.

 

wet uses the same hole you tapped for dry it just mixes the nitrous with fuel as it comes out of the nozzle. direct port is the one you drill your intake manifold for. zex makes a dry to wet conversion kit actually. it is rather expensive tho. <--$300. in my opinion if you have the dry kit just use it but make sure too get an egt gauge.

 

Ok, my Zex install manual has 3 listed on the back. 55, 65, and 75. It lists fuel jets and nitrous jets for all 3.

55:
n2o jet- 32
fuel jet- 36

65:
n2o jet-35
fuel jet-34

75:
n2o jet-38
fuel jet-32

 

thanks
