i'm going dsm 450's w/ fpr should i ditch the pump or keep it?

 

with 450's, there is no need to upgrade from a stock fuel pump. you can keep the pressure stock since the injectors will be flowing more.

 

thanks anybody else

 

nope he pretty much summed it up

 

if you're going over 7psi i would upgrade to at least a GSR pump. (or you can add a second pump in the tank with the stock one like the supra guys do- for $20 on ebay you can have enough fuel to run upwards of 25psi of boost.. )

 

I second the Filthy ScareCrow... If ur gonna boost higher get an uprated fuel pump like a Walbro! Your only gonna need one later so u might as well get one now and be prepared...
