Hi, I have a Grainger MBC i want to fit. I have a boost gauge fitted to monitor the PSI. I am trying to locate some fiiting instructions for the MBC.

I have seen fiiting instructions for a 99 UK impreza, but there are some subtle differences in hose pipe set up. On the 99 uk version the hose from the Wastegate and turbo inlet pipe has a 'T' piece which I guess spurs off to the Boost solenoid. In my 94 WRX the hose does not go from the wastegate to the turbo inlet. Instead it appears the wastegate hose goes to the bottom of the boost solenoid, and the turbo inlet hose goes to the top of the boost solenoid. So do I fit the MBC in te same way as the 99 uk version and then block of both open hoses from the boost solenoid.

Appreciate any help

Thanks

Mark.
