I LIVE IN A COUNTRY WHERE AM ONE OF THE 2 EVO 9 OWNERS. THE MITSUBISHI DEALERS THERE ASKED ME NOT BRING IT TO THEIR SHOPS FOR REPAIR SINCE ITS NOT A MODEL THAT THEY SELL IN THE COUNRY. BOTTOM LINE, I PURCHASED THE CAR WITH A BLOWN TURBO AND FIGURED THAT OUT AFTER ME AND MY MECHANIC SPENT WEEKS WORKING ON IT, IN THE MEAN TIME I BOUGHT A STOCK BOV, A NEW WASTEGATE SELENOID, A NEW EGR VALVE, A NEW EGR SELENOID, THE TWO O2 SENSORS, ETC.. AND FINALLY I PURCHASED A NEW STOCK TURBO. AFTER INSTALLING THE TURBO THE CAR WORKED FINE AND BOOSTED AND IT WAS FUN THEN 4 DAYS LATER I STARTED HEARING A LITTLE WHINING FROM THE ENGINE THAT BECAME OBVIOUS LATER AND MOST OF THE BOOST WAS GONE. I RUN A LEAK TEST AND I FOUND A LEAK FROM THE Y ( y SHAPED HOSE) HOSE, ONE OF THE WG SELENOID HOSES AND THE THROTTLE BODY SEALS. I FIXED ALL THE LEAKS AND REPLACED THE TB SHAFT SEALS AND NOW THE CAR IS BOOSTING BETTER BUT NOT LIKE IT USED TO WHEN I FIRST INSTALLED THE TURBO. I STILL HEAR THE WHINE ESPECIALLY WHEN I CHANGE GEARS AT HIGH RPM ( METAL STOCK BOV) PLUS WHEN THE CAR IS ON NEUTRAL N I GIVE IT GAS FROM THE TB THE ACTUATOR DOESNT MOVE AT ALL . WHEN I FIRST INSTALLED THE TURBO THE ACTUATOR USED TO MOVE !!!!
COULD IT BE MY WG SELENOID WENT BAD?? MY ACTUATOR CAME WITH THE TURBO NOT EVEN 500 MILES IN THEM!!! PLEASE HELP
