intake manifold questions
intake manifold questions Ok I just got my car tuned at Revxtreme and Jeremy told me that I didnt have the ls6 manifold even though I thought I did. He said because it had egr provisions that it wasnt an ls6, I got it from my friend and he said it was a ls6, but I just took his word. Are all ls6 manifolds without EGR or were there some. Also if I have an ls1 intake manifold how much is that holding me back on my dyno numbers. I hit 370 hp with the mods in the sig, with a question mark on the intake manifold.

If you do in fact have the LS1 and not the LS6 then it's holding you back at least 7-10rwhp.
In the middle between the fuel injectors. Here's the breakdown.
The Stock 2001-2002 F-body LS6 is 12561184.
The Z06 LS6 is 12573572.
The old LS1 intake with the EGR setup is 12560688.
97-00 vette LS1 part # is 12556333

If it looks like the stock egr kookup then it's a Lingenfelter adapter on it I had one on my old LS6 intake. If it looks like a threaded peice of tubing in the egr area of the intake then it's the SLP LS6 intake.
