Intake help

I'm going to be putting a FAST intake on my 6.0L engine rebuild but should I put new injectors and throttle body or will stock work with this new bigger intake?

A stock 90mm throttle body will bolt up and work on a FAST 90/92/102. Whether you need larger injectors depends primarily on factors other than your intake manifold.

What is the complete engine setup, what is it's going in, and what are the goals?

As you proceed along the typical path of engine modifications, such as headers, cam, heads, and intake, the air flow through the motor increases. At some point the cumulative effect of increases in air flow necessitates a corresponding increase in the size of fuel injectors. So, any time a new modification is done it may, or may not, trigger the need for large injectors.

Just make sure to have the PCM tuned when you instal the bigger injectors, a lot of people was down the cyclinder walls with fuel when the computer isn't calibrated for the increase in fuel.
