Im looking to get an engine rebuild and upgraded injectors.

 

Was thinking to my self.... At what point does the pump get maxed out or close to it?

 

Ive always had the notion that its better to pay a little more and have something run at 60% of duty cycle rather than 90%.

 

Im looking at getting 740cc injectors over the 555 for this very reason.

 

Can someone please advise me on the pump, and if it is worth replacing then what options do i have?

Stock pump is good for 600+ if it's in good condition

so just a regulator needed then? maybe

yes a Decent one not these Cheap £20quid ones of Ebay and needs to be 1>1 Rising ( for turbo aplications )

is that a make? 1 to 1 rising

Sorry my bad left some info out ... 1to1 Rising Pressure ... so 1psi of boost = 1psi of fuel pressure once its been set at its Base Pressure of 43psi for the 300z @ 0 Vac/boost

Mark can You put any link from eBay to a preasure regulator like this please?

Some thing like this Mark??
