Default LS2 intake on a 5.3L LH9

Hello,
im new to the forum! I have a 2011 chevy colorado w/ the 5.3L (stock). Looking into swapping my intake for an LS2 intake. Probably out of a trailbrazer ss, what injectors and fuel rail can i use? Will all my sensors bolt on the intake? And most importantly, how much HP gain??

The truck intake outflows the Ls2 piece. You would be better off with an LS6 intake if you want to switch to a car style intake.

Im sticking with the truck intake due to more torque. the ls6 will fit the 5.3 but it wont fit my throttle body.

The Ls2 trailblazer intake is the same piece as the one you have. It may be a little different, but it won't be worth the swap in terms of gains.

Yes, you will see gains if you port it, but you didn't say you were porting it.
