NB valve cover swap

Yeah, it could be done, but you would have to fashion a mounting for the CAS and getting that right may not be the work of a moment. But you would need to really want that Protege VC for the effort to be worthwhile and butchering it for the sensor may defeat that purpose.

^^ sorta reverse of people running crank & cam sensors on earlier NA / mk1 cars
Rich.

suppose aftermarket ecu would be programmable to read this signal?.

This may also be doable, but the same comments apply about getting it in the right location. Wiring would be the very least of the problems. I don't know enough about the rear-mounted CAS sensors, were they driven by the cam? or do they use a non-contact pickup like the NBs? Either way, there is a significant amount of modification required. Easier to make up a jig from the current mounting and replace the sensor with the threaded version to get the correct depth - I have seen these used to try and get around the OEM sensor's propensity to fail. In fact my previous post may have over-stated the difficulties in adapting that VC for the NB sensor or a similar sensor.
You would assume so, but maybe the OP is not running an aftermarket/programmable ECU ... although if that is his car in the photo it would seem likely.

The NB2 has a cam angle sensor at the back end of the intake cam shaft. You could drill a hole and mount it there. But you would also need to switch to a cam that has the markers needed at the back end to give a trigger signal to the sensor. The NB2 cam would do, but it of course comes with all the VVT hardware on the front end. Not really worth the work and extra purchases.
early cam sensor.
The early cam angle NA sensor engages with the exhaust cam. The cover for it's insert is still on all the later heads. And there are some flanges on the back of the later exhaust cams that might well interface with the early sensor. Still a fair amount of work to switch from intake to exhaust cam timing signal conversion in the ecu.
Your cam wheels will be exposed unless you also source a B6 upper timing belt cover.

I've ran that VC on a BP4W head with a 36-2 tooth crank wheel for about 10 years.
The head, intake cam and valve cover already have provisions for the CAS.
All you need to do it to open the CAS and modify the "wheel" in to only have 1 tooth.
You only need the CAS for sync. It tells the ECU which stroke #1 Cylinder is on, the crank wheel tells it where the crank is.
It is absolutely simple, effective and can be completed in a matter of an hour or two.
