First pic- Is it ok to take off the air bypass solenoid valve? The reason why I want to take it off is cause I accidently broke it . Will this cause any problems? The car(87 TII) runs fine without it. The car DEF has compression surge really bad. PIC 2 is how I have everything set up. I've read that I should run a DIF vac line for the BOV(which is home made). What would you change with this setup.

The line for the pressure sensor does not have a restrictor pill but I was told that my 3 way adapter has small holes so the restrictor pill is not need. If I need one where can I pick one up?

Thanks MATT

 

run the BOV to the lowest nipple on the front of the UIM if it's open. that eliminated compressor surge for me at least. Your other option is to drill and tap your ACV blockoff plate. Use a 1/8 NPT tap and then screw in the appropriate barbed fitting. restrictor pills are available from mazdatrix. call them up... or actually it may be on the website as a "vacuum orifice"

 

So the front of the uim (3 nipples)! I do have my emm removed. So this front nipple still has vac right?

WHAT about the Air bypass solenoid valve? Would that cause the nipple that I'm running the pressure sensor off of to not have vacum?

 

Your Air Bypass Solenoid is done right.

It won't effect the vacuum on the front, bottom nipple.

Another source of good vacuum would be where you put that Blue cap with the twist tie.

Pasted to the underside of the Turbo cars hood, WAS a decal like in the jpg attached.

 

Thanks HAILERS & ARGHX!

I think I'm going to run the BOV off the blue capped spot. Then hook up the pressure sensor to the 1 nipple on the UIM underneath the BAC. How does that sound to you guys?

Also I'll purchase a restrictor pill for the pressure sensor. This is needed I know but is there another way?

THANK YOU. The OP's pic has provided me with something to compare my setup too. I've been trying to get it to idle for days, and this is what I needed.

 

What kind of setup are you trying?


Thanks for the help guys

 

I'm trying to get my greddy bov to work here... but lo, the adapter didn't have a bung for the bacv hose. So the car wasn't idling. But even after returning it to stock, it still didn't idle. I'm gonna use your pic to make sure I have everything in. Thanks for labeling too. Is that the stock setup?

 

It's close to the stock setup. I'm still using the stock BOV! So yeah the factory would be the same vac lines.

Did you put back on the stock air intake and all? Maybe if you take some pics a second eye could look at it for you which sometimes helps.
