Anyone got some advice to lend me, i need to fit a R-spec 3 port boost solenoid to my 2003 blob eye wrx and need some fitting instructions or diagram. the boost solenoid I've got is from ebay item no 221484947871. Thanks

 

If you currently have a 2 port solenoid then you will need a remap for this and its usually fitted by the mapper at time of mapping. If you already have a 3-port and your swapping like for like then port 1 is left open with no connection or you can vent back to air intake. Port 2 goes to the nipple on the wastegate actuator and port 3 goes to the nipple on the turbo. I have one waiting to be fitted in the next week.
