I have just purchased a boostvalve not a bleed valve, the instructions i have are for a later model us 02 wrx (my car is a my97 uk). Can anyone tell me if this is the same as a dawes device as on my instructions it states to cap of the turbo nipple were as on the dawes instructions the turbo nipple is used. I have fitted the valve as per the instructions i have and i am running 14psi can someone please tell me if this setup is safe ie not using the turbo nipple as a connection.
