Expert eyes know that is not a Ziptie... It is a Plastic Master Link and Wire:D. I have a new 130 link EK ZZZ chain coming in the mail sometime this week.

I am have been trying to work out the location of the oil tank and I will know more after I get the turbo mounted because I also have to make room for the wastegate and wastegate exhaust. I will be running a separate downpipe for the wastegate because there is NO way I am going to get it plumbed back in to the turbo downpipe.

I started tacking the header together today and found out that I need to talk to the engineers at Yamaha. They could have pointed a couple exhaust ports in the right direction to improve the ease of installing a turbo... Tomorrow I hope to get the aft engine connected to the turbo and part of the front engine header tacked together. Buying a twin scroll turbo compounds the exhaust build 10 fold but in the long run I hope it helps.

I made some progress today on the exhaust (Jesse James can bite me:D). Working with schedule 40 pipe is easier said than done but I managed to get everything tacked together today. I still have to finish welding it and check for final fitment. Then I have to find a good spot for the wastegate, grind the welds and throw a nice coat of paint on it.

sch 40 pipe, is their any reason for using such a thick pipe? I would think you'd want something lighter sch 20 or even .095 wall tubing would work.
I was wondering when somebody would ask:rolleyes: When it comes to building an exhaust header for a turbo you only have a couple choices. Stainless, thick mild steel and exotics like inconel. Stainless is light but has a tendency to crack and it is expensive. Inconel is crazy expensive... Mild steel is cheap and works well as long as it is thick enough. That is why if you do a google search you will see plenty manifolds built out of schd 40.

For my build weight is not an issue it is actually a plus. You are correct I could have used schd 20 but that is really the thinnest material that you would want to use on a turbo header. If mild steel gets to hot in the exhaust system it will start to flake and the metal flakes can damage the hot side of the turbo. Plus schd 40 is very easy to get and the weld elbows come in 15, 30, 45, 90 and 180 degree bends at a reasonable price.

Getting very close to finishing the exhaust and moving on to the next CHALLENGE. I added an exhaust bellows to take up the thermal growth and to aid in removed/installation of the exhaust. I also tacked the final portion of the down pipe in place. I am very happy with how streamline the exhaust is:D
