Hi,
Do I need to upgrade the fuel pump for intake, dp, cat-back and aftermarket intercooler with Power FC at 12psi?

Thanks

 

You need to see what kind of fuel pressure you are delivering to know if you need an upgraded pump or not.

 

Good point, I believe that with your mods the stock pump will do. Assuming it's working properly.

 

Do yourself a favor and buy a better pump. The stock pump is for ****. Get a nipendenso, cosmo, or bosch. Shouldn't cost you more than $300 and will be money worth spent. Its very easy to install also. Will only take you 15min. to do.
Dissconnect neg. battery terminal.
Pop your trunk. (lift carpet out)
Disconnect electrical connectors on top.
Un-screw the top lid off.
Dissconnect the two fuel lines. (some fuel will come out, no to worry)
Next pull the pump out. Thats it. Install the new one just the same way the stock one is installed.
