keep hearing of these 3 port boost solonoids and that they are a good addition to the scooby i have a 2000 turbo and was just wondering what they are where they are under the bonnet and what improvement it will give to my standard car apart from exhaust cat back?? also are they easy to fit as i am thinking of bidding on one on ebay

Unless you planning a remap anytime it's not really worth it.

Thisll surprise some, but I have a question (and my head is completely full of Porsche turbo stuff now, causing me to forget much of what I know about Imprezas):

Is the boost solenoid the mechanical link between the ECU and the wastegate, enabling the ECU to control boost pressure by reducing flow of exhaust gas to the turbine? This function on a 944 Turbo is performed by the cycling valve (unless you have a manual or electric boost controller, in which case its the Dawes or the A'PEXi or Greddy or whatever which controls this, either indirectly with the MBC or directly with the EBC).

A three port will allow finer boost control but absolutely no point without a remap. In fact, without a remap it could have serious side effects.
