I built it on a late '93, so it had a VVIS inlet manifold.tjts1 wrote:rozorx
Great write up. I have a quiestion. Were you able to retrofit the VVIS monifold on an engine that didn't have it before or did you simply over ride control on a car that already had it? In the US, Volvo put VVIS on 850s made in 93 and early 94. All cars that had 4 stud wheels. All 5 stud wheel cars don't have VVIS. I want to retrofit a VVIS manifold on my 96 850. Does it bolt up to the engine the same? Do you know if that is possible?
I am not sure if the mountings are the same as for the newer manifolds without VVIS. If it fits, you will also need the solenoid. Check the vacuum diagrams. Exept vacuum hoses you will need a non return valve and a T coupling piece.
