LSX intake manifold?
I would stick with your LS6 intake. I bought the LSX and now I regret it being that there is some major quality issues with the LSX intakes. I don't think they are worth the money.

I would maybe wait and see what happens with the new GM LS2 intake and if/how it can be adapted and how it performs.

Really, what kind of quality issues are you having? I have had 0 with mine as well as my freinds.

i've heard bad things off stock engines, but you really shouldnt have to replace the manifold or throttlebody with stock engine, plus you cant expect great gains from stock engine, but if you have heads and cam, or stroker or anything major, then i've definately heard of 30+ gains from going to lsx.

I've had no quality issue's with mine in fact I think the quality is good and I also got a 27 rwhp gain over my old LS6 intake and ported T/B and thats with a small B1 cam and Absolute Speed stage 2 heads.

I definately noticed a gain on my car by going to the LSX from my LS1. My car had all the boltons (except TB). And the car isn't even tuned yet (definately needs it) Unfortunately I never had a base dyno or track time before, but I will be heading to the track sometime soon.
Yeah, seems like this intake really performs. But as said above, it might be worth it to wait to see what the norm is w/ the LS2 intake.
If I recall properly there were only 2 tests, Futral (spelling?) which had good results and TPIS, who did not. I'm going to wait.
