Hi there

I am about to install a Tomei Arms Turbo (which falls between the Fp Green and the Fp Red) I order Sard 760 cc Injectors now my question is do I need to upgrade fuel rail and fuel pressure regulator also ??? Some people says yes and some say I dont need to

Please Help

 

Stock fuel rails are good for some serious power. What fuel pump are you running?

A regulator isn't necessary unless you have a aftermarket or bigger pump. Plus, you can raise the stock fuel pressure to get more out of fuel injectors.

 

I would do the fuel rail but i don't think it is absolutely needed with that type of setup. You will be fine with the stock FPR. Make sure you're pump is upgraded. Good luck.

Stock rail is good till about 700whp, and stock fpr is just fine for a walbro or double pumper

 

No. You definitely do not need to upgrade either your stock fuel rail, or your stock fuel pressure regulator.

 

I am running a Walbro 255 , and thanks guys for the the help so stock fuel rail and fuel pump is ok for my set up awesome i got some more money in my pocket

 

You still need the walboro, stock rail and regulator is fine.

 

I have seen a car with stock 9 fuel pump and an HTA 35R, from what I was told the tine was really hard because they thought it was a 255 but he made almost 500WHP with it. The stock pump can surprise you. even though I would put in the 255. Just wanted to tell my story :-)

 

wow 500

 

most people change there rail when they goto -AN supply & return lines.

 

I would not risk running a stock pump with that amount of power!
