I use to have a WRX :(

Question I just did the boost sol mod and found a small brass restrictor in the line.

I just did the mod here. http://www.scoobymods.com/forums/sh...hp?threadid=542

But I did it a little different.I just ran a new hose from the solinoid to the T-fitting and put in a 3/16 T.

I noticed something strange in the tube between the T-fitting and the out put side of the turbo.There is a little brass reducer inside the piece of tubing it has a really small hole in the center of this plug...It looks like some kind of restrictor...Does anyone know what this thig does If you remove it will you gain or lose performance....Trinity help.

Thanks Bill(New Guy)

Its a restrictor in the hose and it is needed. I know a manual boost controller wont work correctly without that piece. Dont lose it.

Damn..I just went to the Boostmonkey page and did some reading .I guess it`s the boost solinoid restrictor? What the hell does it do?...It looks like it limits the amount of boost the turbo makes? According to the info on boostmonkey if you remove it ,it allows the turbo to make 17psi of boost...yes ,no ,maybe?

HI.
quite the opposite removing the restrictor will give you less boost
the restrictor delays the signal going to the solanoid , solanoid opens a little later building a boost spike and so you get the car to boost to lets say 1.0 bar and drop to 0.8 steady .
if you can get/make a restrictor with a smaller hole ( i think the original is 0.13 m"m ) then you get more of a spike but also maybe fuel cut .

I believe it's not a delay insomuch as you simply get less pressure to the other side of the restrictor. If you make it smaller, you will get more boost, depending on where it is. This is what the 300ZX TT JWT kit does if I'm not mistaken. Someone should sell smaller restrictors for a free upgrade in boost. Then you can get factory ramped 16 psi of boost. I haven't looked at it much so I'm not sure if this is how it accomplishes things or not.

you will only get a boost spike after that boost will return what ever your ecu sets , we tried different restrictors but they only change the spike .

I don't remember seeing this piece when I installed my EBC. Is it something that matters with the EBC? Meaning, how does it change the way an EBC works?

Thanks,

I don't think it matters with an EBC as an EBC is controlling the solenoids to give you the boost that you desire. With a MBC, there's no computer helping out. I replaced all the hoses and used the included hoses from my Blitz SBC-ID and everything works fine.
