Started making a couple of manifolds.
I finished making a stock manifold but I wasnt happy with the space for a dump pipe.

I ended up leaving it and starting a manifold on a rb flange.

I am trying to fit a 4 inch dump pipe so I spent the day mocking up the manifold and turbo and dump pipe.

The 4 inch pipe may need a dent in it to fit. It will still have the best chance of limiting exhaust back pressure but I'll keep trying. Maybe a few pie cuts might get it to fit cleanly.

A couple of photos of mocked up manifold, 7675 turbo and 4 inch dump pipe.

I also bought a 6466 gen2 t4 divided to try.
