Nitrous Spark Plugs

Hi,
Im building a 370z with a zex kit intended to be used for 75-100 shot. The stock 370z spark plugs are heat range "8". My question is: Should I go for a heat range of "9" meaning one step colder? I read there are some guys with turbo kits with heat ranges of 8 and 9...

thanks.

From my understanding the stock plugs (Denso FXE24HR11 I believe) are heat range 7. I think most who boost or spray switch to the GTR plugs (NGK DILKAR8A8) which are heat range 8 - that's what I have in my motor now.
