I wish some newbies would take the time to read the entire thread your posting in. Update : Santa Claus is going to be running a little late for those wanting this intake . It will not be released this year , but looks like it may happen 2nd week of January .

So with my understanding, this LS2 intake will basically be an LS6 intake with a 90mm TB flange. So would this end up being a better choice than or a good option to replace a TBSS intake? I have a TBSS intake for my 6.0L with 243 heads, but if I can get as good or better flow with this Dorman intake compared to the TBSS intake, have it in a smaller package, and still get to retain my 90mm DBW throttle body, especially without the price gouge of a FAST intake, I think I may be on board for one of these!
LS2 intake better than TBSS Nick_R_23, I am not sure the LS2 intake is a better choice than the TBSS, In the article by Hot Rod http://www.hotrod.com/articles/20-ls...ifolds-tested/, the TBSS manifold rated very well unfortunatly they did not include the LS2 intake in the shootout. I have tread other articles that the LS2 intake was not as good as the LS6 intake but in the shootout the TBSS did out perform the LS6 intake. Just an FYI I run a TBSS intake and paid $50 for it not sure I would spend $200 + to go backwards, but guess we will have to wait and see how well the Dorman LS2 performs .

LS6 vs. TBSS:
LS6 Peak Power: 557 hp at 7,000 rpm | TBSS Peak Power: 562 hp at 7,000 rpm - 5 hp difference
LS6 Peak Torque: 483 lb-ft at 5,000 rpm | TBSS Peak Torque: 497 lb-ft at 5,000 rpm - 14 lb-ft difference
LS6 Ave HP (3,000–7,000): 432.0 hp | TBSS Ave HP (3,000–7,000): 444.4 hp - 12 hp difference
LS6 Ave TQ (3,000–7,000): 450.9 lb-ft | TBSS Ave TQ (3,000–7,000): 464.6 lb-ft - 14 lb-ft difference
LS6 TQ at 4,000 RPM: 454.3 lb-ft | TBSS TQ at 4,000 RPM: 469.5 lb-ft - 15 lb-ft difference
When put side by side, I think the differences are fairly negligible considering the handicap the LS6 has with the smaller opening. I think that with the 90 mm throttle body adapted to the LS6, like what Dorman is planning to offer, will easily surpass the numbers of the TBSS.
need4speed069, This intake will only be like the GM LS2 in that it will bolt up. The runner design and the material used on the GM LS2 are it's shortfall. This intake will not share those.
Codyvette, I hope you are correct it will be great to have another option for LS intakes, I can't wait to see the first head to head dyno comparison, especially because my next LS swap will be a 3rd gen Firebird and the TBSS manifold won't clear the hood.
I am interested in this, though a little annoyed it's out so soon I was under the impression it would be after summer. I would have held off on their ls6 intake I am currently butchering.
