There was a one off supercharger kit made for a member here. That has since been sold and I think someone with a G tried to modify it for his car. Turbo wise, anything made for the VQ35HR will work with mods. So you could get a Greddy or GTM kit, availability is somewhat limited and cost is big, those are both twins. I don't know who makes a single specifically but honestly twins might be easier since there are dual throttle bodies.
FWIW, it's not cheap. GTM kit goes for ~$9K and the Greddy is like $8K. That's before installation costs and tuning.
