Gaspo's 99 trans am project

I would do dual pumps right from the get go. A single isn't going to take you much past 10 PSI safely. It only takes 1 instance where the pump gets hot and drops a few PSI to melt down that turbo motor.

makes sense. Are stock lines and fpr and rails ok?

What are your power goals?

What are your power goals?

Mid 600s?

Mid 600s?

to the tire ?

i agree with those guys.. 60# injectors will be plenty for that combo.. i also would advise upgrading the fuel lines if you want to do those numbers safely.. i would do at least -8 feed and -6 return. you will also want to go with aftermarket rails and fuel pressure regulator as it is much much safer too. one drop in a safe amount of fuel and its toast. kind of like the fuel pump situation.

What he said ^

I would upgrade the fuel lines, rails, and regulator for that kind of power. Guys have made it with stock stuff but guys have also burned there shit up trying.

I'm running dual 255 and stock lines with mine but I don't plan on turning it up much past 525-550 until its all upgraded.

i agree.. i wouldnt go much past that point if you arnt going to upgrade everything else.. plus you have a 6 spd so its going to show better numbers than mike will with his auto..

sounds like i have a good shopping list to start towards!

[Nocooler]

I'd add an NGK AFX wideband to the list - and HP tuners.

With turbo cars your always playing with them - might as well have the proper tools to tune it.

i've got a lmc-1 wideband in it right now. hp tuners is a good idea. when i sell my engine, do i sell the wire harness and computer with it? or keep them? will they work for a 5.3?
