Radiator: CSF or Mishimoto?

Seems like the easiest place to put the sensor would be the water housing at the front of the engine on the timing cover. Unless you wanted to be super clean and remove the rear water housing from the heads to weld a bung on.

Pretty soon I have to make a billet front water housing anyway (one that clears our front throttle intake manifold), so I’ll keep this thread in mind when starting that project.
