Default what jets sizes to use on my nitrous oxide wet kit

what size just do i use for fuel and for nitrous oxide. what are other people using. what jet sizes equate to what horsepower. also if i boost more should i use a little bittle larger fuel jet to compensate so it will not be lean, since i dont have injectors. any help would be great.

i am pretty sure the proper jet to choose would be relative to the fuel pressure you are running. the wrx runs on a 1:1 ratio. for example if you see 35 psi fuel pressure at zero boost then you should see 50 psi at 15lbs boost. what i am trying to say is i feel that you should not have to change jets for higher boost due to the fact that the stock pump will raise pressure according to boost, thus providing more fuel through the nitrous fuel jet. i used the standard 50hp fuel jet with my nos wet kit (#50132 i think). i have not seen any high egts or lean conditions. just be aware that you will see a boost spike of about 2-3psi with the nitrous engaged. i used a turbo xs dual stage boost controller and keep my low setting at 13-14psi for nitrous use and usually see around 16 psi on the bottle. i hope this helps.
