ok so here's my situation....
i got 4th gen v2 sc, manual, with stock pulley...

i want to upgrade to the 3.125" pulley with 8:1 FMU disc AND
VI mod...

now the question is... can my car handle this "as is" or do i need bigger injectors and Mass air, or ecu upgrade or what?
what i want to know is can i put those on my car and just go?
for some reason it sounds too easy to just put those in and i am good to go, know what i mean? well i might just be paranoid... thanks guyz!

p.s. what other gauges do i need? i have AF ratio, boost, and oil pressure for now...thanks again

 

With a V2 you will be making, what, 11 psi? So you'll be up around 110 psi fuel pressure. I think you should be able to do it, but you'll be close to, if not at, the limit for what the injectors can handle. It would be safer if you went with larger injectors and lower fuel pressure.

 

what if i just went with the VI mod only... do it need anything else? or is it just simply plug and play?

and if i went with larger injectors... which and where do i get them?

 

The VI is plug and play.. BUT you will be running LEANER above 5000 RPM


300z TT injectors.. junkyards 300z forums..etc

 

what he said, and I recommend you get a SAFC of some type to add fuel up top.

 

good to see you back

 

thanks guyz... 'preciate it...
