Just Got My Manifold...
I thought I might add a few things.
1. Don't get stuck on the FP30; it is a GT30 reengineered to fit on a DSM and it costs more. You'll need a manifold either way so make it fit a straight GT30 and save a bit of money. You can buy those from FP as well with the same setup I am sure.
2. The HKS kit comes in two flavors. GT2835 and GT3037. The 2835 kit accepts T25 flanged turbos. The GT3037 accepts T3 flanged turbos. It would be a waste to put an old-tech turbo onto something like that. The HKS stuff is mismatched a bit compared to straight GT turbos for a bigger compressor side or faster spool; depending on how you look at it.
3. The HKS kits are setup kits. You cannot get just the manifold. They cost around $5k+ new.
4. The RRE manifold will not fit due to space constraints with the DP and possibly WG. It is designed for DSM.
5. It's better to mount the WG on the collected area. HKS knows their stuff.
6. Breakage is from poor build/design, not because it's stainless.
I've built kits to bolt GT turbos to cars before. Namely WRX and working on EVO now.

HKS offers one for the stock turbo as well..the one shown is for the GT series, and is flanged for an external.
One one from Roadrace is the turbonetics maniold....not a bad unit, but won't fit an Evo 4-8 head

I wish i could scan this picture of what i mean, I will see if i can find one later. If companies actually made these we could have even flow to the turbocharger and excellent boost creep supression.
On an related to the actual thread idea: Are you using an HKS GT-RS turbo, or the new Ballistic series.

The exhaust side of the compressor? Those are the two sides.
Ideally, you want to bypass exhaust gasses before it ever gets into the turbine housing. You TH can be far more aerodynamic that way.
I've used Garrett GT turbos, not HKS's modified stuff. They do a pretty good job of making the match a little better but both have their pros and cons.

Here is a bad pic. But I think you will understand better what I mean. The wastegate is on the turbine housing and the gasses are routed from the to its own external pipe. It could be routed back into the original exhaust at around 18" downstream with a smooth transition fron 2 pipes into one.
I got this information from the "Maximum Boost" by corky bell. It is an excellent book worth looking into.
any way both of these ways of bleeding or holding boost are excellent. Integral wastegates interfere with the exhaust gasses exiting the turbo, which is less than Ideal and promotes poor wastegate respones at higher boost levels.
:: The manifold shown in this tread is of good design, the only thing I would do is make sure that the inside of the manifold is smooth and not rough from the weld. Maybe have it "Extrude Hone"(d), then coat it. =)

I'm having it extrude/hone/polished. THen im going to thermal coat it, should be ready soon :-) I'll keep you guys informed
Hmm I don't know how good of an idea it is to extrude hone the newer tech turbo housings, but I guess we'll see. Jet Hot, etc. is certainly handy, though. 
Especially given how close all that stuff is on the EVO.
The wastegate you show there is mounted on the turbine housing, not the compressor housing. Just a terminology thing. Yes, that one doesn't look too bad. It becomes pretty tought, though to actually mount the WG on the TH like that when you get into close quarters and big WG setups. That looks like a fairly ideal design as well, though. I was mainly trying to convince ppl not to go with a manifold that was mounting the WG on one runner.

Mark, i updated the terminology.
Actually I think he is just extrude honing the exhaust manifold. You are right though on newer tech turbo's it would not be worth it to extrude hone unless you are making big (600+ hp).

Well I think it may not only be not useful but rather negative in effect. The newer stuff seals a lot better/closer. Honing it out may make it a little worse.

What's the diameter of the exhaust from the cylinder head? Would be interested in a picture of the head with the exhaust manifold removed, rather than take the manifold off my Evo.
The size of the tubes should match the size of the head.
