Hi I own a 1986 z31 TUrbo. Dose anybody know how to install a Variable Boost Controller? I finally figured out how the valve works but I can not figure out what line to cut into for the compressor suction source. The VBC is installed inline with the hose that leads to the pressure side of the wastegate and the other side of the VBC is a vent. If anybody knows anything about this please contact me. Thanks.
