Exhaust Side Project - Step 1
The GTR Exhaust Side Project is under way, what does this entail.. Well I'll try and put it into a few simple points..
Okay so far there are two casualties, a few minor issues and some bad possibilities that came to fruition..
Casualties were two bolts, one snapped off if the rear turbo inducer, but it is just a mount for a hose I don't use, so I don't care, the other is a mount for the recirc pipes, probably going to be need to be cut off..
Minor issues are the water pipes that are frozen in, this was expected as I had issues with this earlier, I might have to go nuts on them though to get them out..
Bad Possibilities is the cracks in the Exhaust manifolds, this WAS expected, but both manifolds?? In the same place.. Well I have taken some pics to show what it is all about.. Here ..
Not quite sure if the manifolds are actually stainless, but I will know more once I get them out, I will also be able to tell wether the cracks were formed by expansive or compressive forces. Which will have an effect on how I handle the repair and the the way that I handle the heat afterwards. Maybe the wrap was a bad idea, maybe the welds can;t handle the heat I am putting into them (900 deg C) on full noise. Maybe the restrictions further down the line are putting excessive pressure into the manifold.
More later.
- Replace the Stock restrictive front pipe and aftermarket dump pipe with the GReddy Extension pipe set as pictured here ..
- Weld/Repair leaks in the exhaust manifolds.
- Ceramic Coat the turbo exhaust housings, manifolds and extension pipes.
- Replace all gaskets in the area.
- Repair/replace oil and water lines as necessary
- Clean and polsih the heat sheilds so that they reflect heat as well..
