13 psi is about the max you'll be able to run on 91 octane. With the 9lb pulley and a 2.85 sc pulley, my car made 12.86 psi and 586whp on e85 with the same upgrades that you have. I can't remember what my 91 octane numbers were but was probably a little over 500.

I would go flex fuel. 91 and e85.

You list a single walbro 520 but then you show a CJM twin pump. Why would you have a twin pump set up with a single pump?

I got the twin fuel pump assembly for a pretty good price. Also when I took out my stock pump assembly the rods were already broken. So instead of buying a new nissan oem assembly I just bought the twin assembly for a good price.

And when you want to go for big power (and you will), you'll need twin pumps.

You'd never be making enough boost to lift the heads.

Haven't our engine's been known to do that around 12/13 psi

as far as flex fuel/e85 would this be all I would need https://www.specialtyz.com/370z-g37/...-fuel-kit.html ? Also could you point me to a website where I could buy those pulleys at?

The kit shown seems to be for NA. Seb knows what kit suits you. There are options out there.

For flex fuel you will need the Zeitronix ECA-2. I'll find the links for the pulleys.

thank you very much for the help. Will I have to change out the impeller with the new pulleys or should I be good?

It depends on your boost goal. But for other parts in its internal, the stock head unit won't hold up for long if your using exactly the same setup as that redondoaveb is having. He ran and will be running 928's rebuilt blower.

Do you have the Sci or Si blower. If you have the Si then I wouldn't change the impeller.
