Hi I am trying to obtain some info on turbo's I hope you guys might be able to help me. I own a 1988 nissan 300 zx Z31 import which came out of the factory with a rb 20 nics redtop, I since have replaced with a rb20 silver top , the mods so far I have done are as follows... fitted a inter cooler.. 3'' exhaust.. dump pipe..cat..bov..& a gtr fuel pump.. she goes a lot better now but after 3 months I feel that I'm used to the power improvment & would like to gain extra hp.. this leads me to the next step.. I am considering chiping the ecu ..a diferent Turbo and possibly last change would be injectors and a good dyno tune... what I have been offered as a swap for my standard turbo is a vg30 do you think this is a good idea.. or what turbo would you suggest..as money at the moment is a big factor.. I am confused which turbo as some forums talk about rb25 neos, garrett, hks..t3 t4...so on & so on.. a swap is a cheap way but is it a good choice?? also reguarding the injectors I have heard either rb26 or rx7 series 4..Lastly I obtained a chip for my ecu with cradle which i am going to try it came from a rb20 with similar mods.. hope maybe you guys might have some advise.
