The Infiniti general forum has serrved us well, as our "Q45 board", most Infiniti drivers here on this bord drive Q's and in there you will see all the Q45 expertise you could possibly need.

PS: Guides dont need to be done on 94's and up. a "nice one" still goes for 7k+, becareful about cheap ones, cuz everything is like 2-4 times more to fix than on a S13.
