Thanks for all the kind words. This is the first time I've worked with sch 10. It's really nice stuff, and I started getting the hang of half way through the first header.
There will be 2 waste gates per manifold. I have not decided 100% where I'm putting them. I'm going to finish the charge pipes and down pipes then decided how they fit the best.

I got it last Christmas and this is the firs project I've used it on. It's a great little saw, but I need to figure out some more jigs and clamping ideas. The clamp that comes on it is very basic and limited. It's a lot nicer than the chop saw with a fiber blade that I've been using for years.
I got the blade online. It's a bimetal blade and does a good job. I keep the fed rate low and let saw take it's time. I have cut enough to make 2 manifolds and blade still has some life in it. But now that I think about it, I should order another to have on hand.

Great job as stated. Very clever ideas on the pipe clamps and temp. turbo mounts. Do yopu plan on any other way to support the turbos? Where did you get the sch pip and header flanges?
Thanks,
Jim

Norotor7,
What welder are you using? Any better pics showing the jig you made to cut the pipe for the turbo flange?
thanks,
Jim

Some people run a pipe off each side of the collector and merge them into 1 gate. But I don't see how it can effectively keep the sides separated. 4 small gates aren't much more than 2 big gates.

In my opinion, 2 gates per turbo work better for twin scroll. If I were going to use a single gate per side, I would want at least a 44. 2 tial 44s cost $740. 4 tial 38's cost $1000. So It cost $260 more to do it the way I wanted. That's worth it to me.

Ya, twin scroll is popular in the import world. The normal thinking in the V8 world is I got cubes to spool the turbos, or I'll use a looser converter to spool the turbos.
I originally planned on using On3 turbos with open housings, but Huron speed gave me a great deal on these Borg Warners. I decided to take advantage of the divided housing that they come with. I was building the manifolds, so it was just as easy to build them for twin scroll as it would be for open. I'm trying a pretty tight Circle D converter, so I hope the twin scroll gets the turbos moving sooner.
