I installed ARH headers still have to install the catted-y and magnaflow catback. And now I am also planning on buying a fast 92mm intake and throttle body. I also plan on getting thunder racing's old man cam with comp cam and comp cams valve springs and retainers. Now would I need new fuel rails and injectors? Don't plan on changing the heads.

 

You won't need rails, just a little bigger injector. Call Jon at FIC, he will set you up.

i'm running stock injectors on my setup

bigger cam than you're picking, and a FAST intake.

they ARE maxed out though...but never ran lean on the dyno.

 

how about the fuel pump?

 

Your fuel pump should be fine. Get some 36lb injectors. Stock rails.

The 42lb green top Bosch injectors can be had for a fair price. You wouldn't need them... but they're just as easy to tune as a 36lb and you've got room to grow.
