I HAVE A 93 JAP SPEC WRX AND WAS WONDERING IF U COULD CHANGE FROM THE THREE PORT BOOST SOLENOID TO A NEWER JAP SPEC WRX 96'ISH TWO PORT SOLENOID AS I HAVE AN INDUCTION KIT AND THE BOTTOM PIPE DOESNT SEEM TO GO ANYWHERE? I JUST THOUGHT IT WOULD BE WORTH ASKING!

 

Why would you want to do it? is it not working? the three port is often used when upgrading the ECU, BRD highly recomend it.

 

MINE KEEPS PLAYING UP AND THE CAR CUTS BOOST AFTER A COUPLE OF HOURS! BEEN OFFERED ONE BY A MATE AND FUNDS DO NOT REACH TO A NEW ONE FOR MOMENT

 

Stick with that solenoid.

What do you mean by 'cuts boost'?, sudden cut?, or just a lower boost level at wide open throttle?.

 

Oh and stop shouting

 

IF I FLOOR IT THE CAR PULLS AS NORMAL BUT HAS A FEW SPLIT SECOND MISSES WHICH FEEL LIKE ITS GONNA CHUCK YOU THROUGH WINDSCREEN!

 

Sounds like fuel cut (too much boost).

What other modifications do you have?.

 

I HAVE A BOOST GAUGE WHICH SHOWS 0.9 WHEN FULL BOOST THEN DROPS OFF.MY ENGINE MODS ARE. K & N INDUCTION KIT,FULL MAGNEX DE CAT SYSTEM,BAILEY DUMP VALVE,FOUR PADDLE CLUTCH. I DO HEAR IN ENGINE BAY WHILE ON M WAY FOR INSTANCE I CAN HEAR A SORT OF BUZZING NOISE. SORRY ABOUT MY POSTS BUT I HAVE ONLY EVER MADE ONE AND NOBODY REPLIED.

 

It does sound like overboost to me, take the pipes off going to the solenoid one by one and flush them out with brake cleaner. There should be a restictor in one of them best to leave that there.

Oh and take your caps lock off

 

Thanx for answering back i will try cleaning them out again tommorrow.
