LS2 Intake on LS6
I searched for threads already on this subject, didnt find what I was looking for. I also had a couple more questions regarding this set up. At first I was told that this intake was a direct bolt on to a LS6 Engine. Now I've heard that it will not fit my LS6 because of the Injectors. Is this true? I also found out that something needs to be modified at the back end of the intake manifold? I have a 03 Z06 with Bolt on's. I tuned the car after the Header install and it dynoed at 382hp and 383 torq. Now, if I do manage to make the LS2 intake and TB work on my Z, will I need to re-tune the Z to make the engine run good? or will the Intake and TB make the engine run lean or maybe to rich without a tune? What will I need to make this work on my car? Oh and I do have the LS2 to LS1 TB adapter too. I will also be installing a U/D pulley. Any Info on this will be helpfull. Thanks in advance.

Total waste of time and money. Your factory intake flows better than the 90mm LS2 intake. You will only make the car faster because your wallet weighs less.
Stick with what you have or step up to a ported FAST 90 or 92. Even at that you won't see a big HP jump until you have ported heads and a cam. Just leave your intake manifold alone and spend your money somewhere it will help.

Thats what I was told but didnt know forsure. I think I might just sell the Intake manifold and keep the TB, then send my stock Ls6 intake manifold to TPIS and get the conversion to a 90mm. Thanks for the input.
