I'm guessing you're rebuilding a 14b. At 10 psi, it won't flow quite as much, nor as efficiently as something like a new t3/t4, so you won't make as much power as another turbo at the same amount of boost. But you'll be approaching the limits of the stock fuel pump. It's better to pay a little more now and get a larger pump for an extra margin of safety than learn the hard way and pay a lot more later by having your engine go lean.Mark7901 said:Im confused, some say bigger pump for 10 psi, some say I dont need it....

Very True...its a TD05H, I guess its a mitsubishi turbo from a eclipse....FreeFlyin said:I'm guessing you're rebuilding a 14b.
