450 is all you can do than... I highly suggest running fuel pressure sender to your ECU though so i can monitor pressure.

kenne bell boost a pump sorted . Increase the voltage to your pump constant 17.5 volts boosts your pump by 75%. I would lock it at 15 volts for your goals.
Find me on Facebook BOOSTED s2000 group Lee Todd.
