can someone shed some light and explain what the previous owner had connected?

 

My guess would be an ebc. That vacuum line goes from the fpr to the intake manifold right?
Oh well, it's better than an mbc.

 

....no the idiot likely did a boost gauge tap there....bad place to do it....get a leak and your FPR isn't gonna work right and BOOM.


A boost controller goes on the vac lines on the turbo.....

 

I have a greddy ebc, wich I never installed, but I was reading the directions and it said you had to "t" into this hose.

 

Tee into it for WHAT??????? Manifold pressure????? There are MUCH less dangerous places to get manifold pressure than THAT.

...maybe that is one reason that so many people out there with all this JUNK on their cars blow them up so often.....

...those directions are usually written for cars other than Subaru's and/or for NA cars that get turbo'd....or hundhuas.


....and MANY people are STILL under the false impression that a turbo'd car is a turbo'd car and I can jsut slap parts on and they will work...

WRONG!!!!!!! Subaru's ARE different.

 

It says it reads the fuel pressure.
I dunno, that's the only reason I could think of that they would tap into that line.

 

How is it going to read the fuel pressure?There is no fuel in that line.It is a vaccum line.In order to read the fuel pressure you would need a sender that was placed in the fuel line before the regulator.

 

Don't ask me, ask greddy.

 

ebc = electroinc boost controller, correct?

could this be causing my boost problem? i have an autometer boost gauge installed and im topping out at 10psi (3,4,5)
