ls2 intake on an ls1 motor??
hey there I'm putting together an lq9 motor with 243 heads and ls2 intake with 90mm tb from a tbss, what do i need to put the ls2 intake on my ls1 truck and where can i get this stuff ? I've heard you need the pigtail for the tb but I'm not quite sure..

yes its an 03 silverado 5.3 with the electric throttle body , the ls2 intake is off a trailblazer ss and i have a performance throttle body +spacer+ cold air intake so I'm sticking with it + it should have more flow then the ls1 and the throttle body is bigger, my only concern is what kind of wiring do i need to hook it up and have it running properly..

I think you have your motors mixed up but that's okay.
The LS1 is a 5.7 car motor, your 5.3 is likey a LM7 with a different throttle body/intake than an LS1.
The LS2 truck motor has a TBSS/NNBS style truck intake.
Aside from that I think they make a x-link adapter harness to run it but someone can correct me if I'm wrong. Also toss the TB spacer in the parts bin, they are just another spot for a vacuum leak and don't add performace.
