you'd be pretty lucky to get 280hp out of those injectors even at 90psi.. depends on the turbo, but your looking at 10-13 psi id imagine

if you motors built with je/eagle, you should be able to boost like 20 psi assuming everything else is done right ....fuel, tunning, etc.... then there is the stock sleeve factor, but the je/eagle's should take it....am I right?

depends on how much boost you want to run. 310s won't go that far. i'd get some 550s

which pump? 440's are good for 350hp at 70psi (rising rate regulator i assume)
and youll need something around 15-17psi to produce that..

94 octane isn't really going to get you much more then 350-370hp at a reasonably safe level..

with the 440's and a dyno, you should get 14-15 lbs fairly safely on pump gas. with a fmu, fuel pump, and afc of course.
