1990 240sx s14 Swap Issue

[BlueGoat]

I know this has been covered I just could not find the the answer by searching. Just looking for a few answers.

I have a 1990 240sx. I put a sr20det (s14 Blacktop VVT) Into the car. Nothing on my gauges work. So my understanding is

1: the speed sensor is the same from KA - SR so no need to look for a different one? (I know the connectors may not be the same)

2: The stock motor was a KA24E. Now If I'm not mistaken.. I will need a DOHC gauge cluster (91 +) in order to get the gauges to work anyways. Is this correct?

3: I have a rip off HKS BOV. It does the flutter... I was told that a BOV that does this is not seating the valve properly? Is this true ?

Thank you guys so much sorry if this is the wrong place I have just searched and not received a straight answer.
