Just wondering if this would be something to upgrade to some polished billet do-dad.

Again, knowledgeable posts only please.

 

you want to put a polished billet dodad that does nothing for performance in a spot no-one will ever see except the guy that rebuilds your engine ?

 

Looks like you didnt read the disclaimer.

Edit: Just to be clear and to help you with your thinking, I didn;t mean polished on the outside.

 

^looks like he was trying to get more info!

 

yeah i did - but could not resist .....
I have seen MM mention that the rails will flow more than you will ever need - how's that ....

 

THank you; that is actually not too bad.

Edited to add: if the rail supplying the sec and P2 injectors will flow 3L/min and more, I would leave mine alone. I installed two 650cc/min and two 720cc/min on that rail and was worried that the rail might not be able to handle the increase.

 

^that's fine many ppl upgrade and dont change the rail(that i know of)....see a small bit of info with the Origninal post make things easier!

 

Im guessing if your doing a custom fuel system or switching to e85 you would want to upgrade. Stay tune for my build thread in next coming weeks. Gonna replace rails and fuel system with bigger.

 

The main reason to replace the fuel rails is to run a return system.
