Traditional way is nitrous foggers in the inlet tracts with a single large fuel fogger in front of the compressor inlet this will allow a low pressure NOS fuel pump to be used but is very variable for fuel distribution which is never a good thing when playing with nitrous. If I was doing another i'd use traditional foggers in the inlet tract but use a high pressure EFI pump to over come the inlet boost pressure - a refinement would use a boost compensating fuel regulator set to 5-6psi static. The pump will happily have enough pressure capacity to use 2 bar boost and still keep AFR stable. Do be wary though as a draw through with dubious fuel distribution will be subject to some detonation which if mixed with nitrous can melt pistons and head quicker than you can pull the clutch it - its unforgiving stuff but total larf!
