Learn me something...tubular manifolds vs ??????
Tubular = 
Cast =
Cast is generally heaver, but requires less maintence/monitoring. Tubular is, in theory, more desirable, but turbo support and manifold construction must be correct, else cracked welds may well be a problem. Tubular is also (generally) considered to be more expensive, given the number of used production LSx manifolds floating around.
I'm using 6.0 manifolds on my turbo project.
Think that covers everything. What did I win?

Where would the turbo(s) go? Here are our turbo headers....
To sum up the differences basically, smoother transitions, lighter weight, better flow properties in most cases. The tubular though has the advantage of lasting forever.

theres a diff between LT's and tubular headers for turbo app.u can use plain LTs for a rear mount turbo setup but tubulars are great for front mounts...ie the original Phamspeed kit.search frcefed98 or hellraiser or armageddon to see pics

Anyone else catch the title? Learn me something... 
Thought that was interesting.
I suggest reading the Turbo FAQ at the top of this forum Quickin. And yes the turbo's mount to the end of the manifold. Are you just comparing tubular to cast? We should not forget to mention a Log type setup. This setup is particularily controversial due to higher back pressures from poorly routed exhaust gases. Do a search as well, there is alot of discussions about log setups, cast truck manifolds, remote mounted (sts), and custom/sponsor manifold setups.

Hi Flo Just Came out with a tubular kit that allows you to keep your A/C. The turbo is located where the battery was located and you relocate that to the back of the car. It is a really sharp looking kit and the introductory price is insane. I would definately look into it and order ASAP.

Why don't you just read the forums instead of asking questions like this. You can go to the big Hi-Flo turbo thread in this forum and get pics of that one. You can search for "PTK" and find info on that kit, or go to www.proturbokits.com and look for yourself. There's a thread about GroundZero's log kit out there too. This doesnt seem like much of a turbular header/Cast manifold discussion as it is you trying to learn about that kits are out there. Take what Jose and the others said already, and start looking at kits. And if you're looking to support that 422 or 436 or whatever, start looking at kits that will support a PT88 and at least a 3.5" DP.
I ran 10.50 @ 137 in a 3800 lb car om pumpgas. Ahould mae about 700 hp to the wheels.

Now I'm well informed what tubular and cast means, and more importantly I now what parts are associated with being tubular and/or cast that makes a kit better than the other.
This site, which is why it's here, did its job. I'm now better informed.
