Default bigger injectors or more fuel pressure...

setup:
b18a1 bottom end
PCT's[ctr's] in 20 over
golden eagle ls/vtec kit
BC3+ cams/gears
pr3 head
an-R header
aebs intake manifold

using a fuel pressure regulator, wideband o2, and a vafc for tuning <U>only</U>.

what would you do? upgrade to 340cc injectors or turn up the fuel pressure?
i should be around 190-204 wheel horsepower after tuning..

OBD1 Prelude injectors work great (340-345cc)... Seems you're running a similar setup to mine. My fuel pressure is at 46psi, with as much as -23% taken out of VAFC at WOT. (Dyno tuned)

bigger injectors will make your life much easier and they will leave you much more tuning room for the future. if you can find some cheap ones id say that would be a good move.
