ok i need to take my ride in for repairs so i removed the mbc and reinstalled the factory lines and now i am reading 12lbs of boost ??
i have the restistor 1 inch from the waste gate is it suppose to be there?? or some where else???
need help so i can take the car in tommorow morning.

 

You probably switched up the lines going to the compressor/actuator. I did that too when I uninstalled my EBC.

 

does anyone have the stock diagram? i have searched for 2 hours and came up w/ nothing. any help will be great even a point in the right direction.

the compressor/acuator ?? and u are probably correct i had to have installed the factory lines in wrong since i cut the factory off to begin with and had to manufature new ones, even put the restrictor in. 1 inch from the wastegate? not sure if that right either. or if it had to be facing a certain way?? please help please please hehe begging helps right

 

Hm, if you used your own lines I'm not sure if the stock system would like that. There are two restrictors in the system, do you have them both in there? You can pick up the entire hose assembly for about $20 from Mitsu. The part # isMN143555. I would post a picture from the tech manual for you, but I don't have access to my tech manual right now (I don't have the CD).

 

Open the hood of your Evo and look down at your battery. Now look up above your head at the underside of the hood. You should see something like the picture below.

 

LMAO!

Are you serious?? How come I've never noticed this... I need to go to my garage and take a look now.

 

thanks for the diagram
can't believe i haven't seen it before.

well my dealer service dept. thinks that the car only runs 7-11 lbs of boost anyway. so i will take it to them like this then just reinstall the mbc when i get it back and turn it back up to 19lbs.

i will pick up the factorys line again thou just incase i need to turn it in again.

 

I think the vacuum hose diagram is a DOT or EPA requirement. I'm not sure but I saw a JDM Evo 7 today and I don't recall seeing the diagram when I was checking out the underside of the hood.

IIRC, 12lbs is the "failsafe" level of the wastegate spring. In otherwords, with no additional pressure supplied to the wastegate actuator the wastegate will open at 12 pounds of boost. My wild *** guess is that you've got the pressure tap leading off of the compressor outlet vented to atmosphere. This is essentially what the solenoid valve does.

 

well since i bought the car w/ 400 miles on it and as a second owner.

i just glazed the cluth/flywheel but told the dealer it has been progressing like this since i bought it. and it must have been the other guys fault. so they will fix the prob monday. now the factory vaccum line i also mentioned to them that they didn't look stock if they could take a look and please repair the damage the other guy made boy am i a stinker.
