What's this? And is it supposed to be capped off or connected to a hose somewhere?

Help me out! i'm learning!

that looks like a clutch bleeder?

haha, I'm just trying to find anything out of the ordinary. I'm a n00b learning more and more!

Hopefully when I get my MBC it will solve problems!

Sounds like normal. When I had an sti I hit the rev limiter all of the time. The evo hits hard at 3500RPM, and does not reward you for revving high. It is not like a Mazdaspeed3 where you have to short shift for the best 1/4 mile time, but after the initial surge the torque definitely dwindles.

That's a good point. I'm getting a new guage and a hallman mbc.

That would be your problem. That's very strange that it has the factory boost lines and no restrictor pill. As previously mentioned you can remove the factory boost line and install a mbc or replace the factory boost lines to resolve this.

Awesome, I will get on this As soon as I have the money to do so (within the next week) And I will post up my results! Thanks so much everyone for your input, and if anyone else has anymore input, feel free!!!!
Thank you!

I honestly think that the lines are not stock, from the T and up to wastegate and Turbo, looks like some random a$$ lines.

i got the same thing

Same exact problem? Same stock mr boost guage?

Does anyone happen to have the stock lines lying around? Is the Restrictor pill just in the one line? or are there more?

Okay, picked up a Hallman MBC today. Putting it on tomorrow morning.

There are 2 restrictors, 1 is at the top by the solenoid and another down by the turbo but for your MBC you wont use either of them. Just remove the vacuum lines that are there and put your mbc in-between your turbo and wastegate. Make sure to connect the ports properly.

What about in between the bov and intake mani?
