Mount the pipe bracket to the engine rails with the bolt already there. I also
mounted the bypass to the rails as well. This keeps the entire set up mounted
solidly.
Test fit the turbine and fit blind nuts under the rails. Also use the countersunk
screws so they are flush. I put all the 3mm screws in the wing mounts before
installing the turbine. This is advisable as access is much easier before the
turbine is mounted.
