Had a prover look around the 90's engine bay yesterday to see what's what.
The front mount intercooler is from an Iveco truck, the turbo actuator is set at a fixed boost of 1.2bar using only the spring tension in the actuator. And in the diesel pump there is a blue spring that is shorter than any spring I've had in a 200/300tdi before, and the diaphragm seems to be made of thicker rubber too with "W13" on the bottom of the cone.
It goes very well with not too much smoke so looks like someone knew what they were doing.
Never seen this blue spring before though?
