New Turbo Manifold Design
My log manifold that I made several years back has developed a small crack btw cyl's 2&3. It's just enough to irritate me, and I've always felt like I could make a more efficient manifold so I modeled one in Solidworks. I think I saw TurboTim post a picture of a manifold of the same design some time ago. I haven't got any material yet, but I took my last final today and should have time to start tinkering with it soon. Here are a few pics. The collector should be interesting..

Yeah, you've pretty much duplicated Paul's setup, just adding an external wastegate.
Shore Motorsports: Fabrication & Installation
What he did on the merge is a lot easier to fabricate than what your model shows.
I'm laying out a similar design for a WRX turbo. Have PS and A/C in the car, so I may not be able to package a symmetrical design. Due to that, and because the turbine inlet is round, getting the merge details right without some kluginess is considerably more complex. The T25's oval flange and 1-1/2 in. weld els make it easy.

I want to know one thing. How does Tim figure out the proper angles when doing this.

Orion/Saml - That's actually something I'm not sure about myself. I've been trying to get an idea from the picture of Tim's. I may have to put another 90* bend there to move it out of the way of the frame rail. I'm not sweating it too much.
Saitrix - I just finished the CATIA course at school a week ago. I can honestly say that thus far it doesn't seem nearly as easy to use for what I am usually doing. It definitely has more capability. but thus far Solidworks win for the average Joe.
Simon/Gospeed - Thanks! It took several days to figure out how to get the the collector to come out like this. That was the only time consuming part. Ya never know. If I find an easy way to make it, maybe one day I'll make a couple more to sell.

The way Tim did it, the merges are all on planes (he might even use a band saw, like the instructions for a straight merge on the Weirtech site). You can lay it out with pencil and paper, ruler and compass.
This Solidworks model is pretty, but the merges are complex 3D shapes. I can't figure out how to make them other than by spending 1000 years with cut and fit or CNC.
I think I've figured out how to make my merges at least planar, and lay it out and fabricate it, but there's a chance the tubes won't actually intersect each other perfectly at the planes. I don't have a Solidworks seat at work. I've thought about trying to use Google's free CAD.

Corky - Yes, using the weldment function you can use boolean functions to combine and then split them. It will then create a seperate part file for each piece.
Solar - Your right, the merging btw runners 1&2 and 3&4 do have some very 3D complex geometry, which would be very difficult to make with out CNC capabilities. I may still have access to a CNC at my tech school, but if I don't I think I can go back and just cut them with a plane and get it "close enough". Although, I would much prefer to do it the right way.
Here is a picture of half the collector. You can see the complex geometry he's talking about a little better.

Instead of coming straight out parallel with the block meeting flange, I think you should angle the wastegate flange upwards more. It has a good meeting point and I think any losses would be negligible.
I was going to say something about the 2&3's meeting into the collector, but there's not much to say. Its not that big of a deal really, and your way looks just fine and clean.
