I need to change the vacuum hosing running from the boost solenoid to the actuator and the compressor housing to the boost solenoid.

What guage or internal diameter is this tubing and does the Apexi AVCR use silicon tubing.

thanks

 

from memory i think it is 3mm but stand to be corrected if wrong.

i was told best not to use silicone hose as it goes soft when hot and can collapse although i had it on mine for a while until i got rubber and did not encounter any probs?

 

^^^thanks

Just visited a Subaru main dealer, they don't know either.....

Anyone else?

 

4mm

 

As dynamix says 4mm at actuator on standard turbo. then if im not mistaken you have to go to 6mm at AVCR solenoid. Usually get a plastic reducer with the AVCR kit.

Hope this helps
