i am putting on my skunk2 manifold on soon. i got a type-r fuel rail and hondata intake mai. gasket on the way... im about to get new rings and seals for the injectors; is there anything else i need to consider? any way to clean the injectors a bit before swapping them into the new set up? i only use cheron supreme with techron! so they aren't horroble but what else can i do while they are out... (no time or funds to have them cleaned and balanced from RC)
