its now a Stage 4.


300zx's go by a MOD list

Stage 1 Intake
Stage 2 Exhaust
Stage 3 ECU upgrade
Stage 4 Crank pulley
Stage 5 Intercooler upgrade
Stage 6 Injector and more boost upgrade
Stage 7 Turbo upgrade
Stage 8 can be a HOLE LIST OF THINGS...


Really anything after stage 3 its you oppion of what your Z is.

Mine is a TRUE Stage 4 now because i went back to stock intercoolers and sold my Apollo 23x11x3.5 FMIC <----- VERY Shitty for the z.
