Sup guys,I plan on upping the boost on my current turbo setup but I have a few questions before I do. I finally recieved my 480cc injectors in the mail (I know I know I should of gone bigger). But I'm worried there not gonna fit in my stock fuel rail. The stock 270 is on the right and the 480 is on the left (still need o-rings). Can anybody verify?

My other question is about my turbo. I'm currently running a 57 trim with a .48 AR exhaust side. How much boost can I run before this becomes restrictive and I need a .63?

Your injectors are fine, they will fit in the stock rail. Id use new o-rings.

Your turbo setup is good too, 480's will max out before the turbo becomes TO restrictive.

How much power do you think these injectors are good for with a safe duty cycle?

At an 80% duty cycle I'd venture for right around 300-310.

Yah you'll want to check your duty cycle at over 12psi.

agreed, i think that 480s will only be good for 300-320rwhp. and yes you should've gotten bigger injectors.............
