Does anyone know of a site that i can check out a break down of VCT on an S14 sr? For example I'm looking for how it works. 5 volt, 12 source. switched with oil pressure or just a solenoid?

Factory service manual... 5v energizes the solenoid, which opens the oil passage to the VTC cam gear. VTC range is about 1k rpms to 5.2k rpms.

Thank you. Are you aware does it return after voltage stops to "home" position or does the computer then pull it back?

The solenoid is or is like an electro magnetic plunger. Once voltage stops, it should return to the closed position.
