What do these do?? They seem to be connected to boost pipes.



Located in the top lefthand corner of the engine bay.



Thanks

 

That'll be the boost solenoid, controls how much boost the turbo delivers - yours is the 2-port variety.

 

there the boost solenoid valve and map sensor.
the solenoid valve controls the boost and the map sensor tells the ecu what pressure is in the manifold.

 

Blooby hell that was quick.

Thanks

 

 

Watching the Grand Prix, so bored

 

know what you mean Jon,

 

While I've got you guys attention

Which pipe should I cut to fit the boost gauge pipe? I'm guessing the black pipe just to the left of the centre of the manifold.

Whats the other small black one to just to the right of the manifold centre next to the pipe that goes to DV? On my old UK car this was blanked off.

 

That is the pipe that goes down to the valve for the carbon canister which is situated next to the radiator[drivers side front].
The pipe you mentioned would be fine for the gauge mate.

 

Top bloke

 

there should be a space on the inlet to use for boost gauge or use the pipe going to the dv, not the bcs u might cause problems

 

Its the pipe that goes to the map sensor which will be ok to use mate

 

I teed off the pipe going to the DV

 

Also a good spot
