how much boost is it making with the restrictor removed?

It was making 10 - 11 before and the same after.

have you done a Boost leak test yet?

Stock BOV?

Maybe you should just spend some money and get a MBC/EBC.

As mentioned by ambush, do a boost leak test. If you find nothing there, then I would get a mbc and see if that helps out. I wouldn't push it up no more than 12psi or so until you at least get a fuel pump rewire done (if you don't have it done already).

The soenoid could be closed. Find out

um yea I have a walbro, and a ghetto front mount with no boost leaks and a greddy bov.

I'm running 12 with the restrictor removed, hks bov, and running a line from turbo to wastegate nipples.

I think I will just do a manual boost controller soon. for a quick small upgrade. I have everything necessary to handle the boost I just need a way to get it there

Are you going by the stock gauge or an aftermarket one? In my experience, removing the restrictor is a negligible difference regardless, a proper boost controller is definitely the better option, just be sure you have the supporting parts to handle it (see: knock, boost cut, datalogging, wideband, engine management, etc)

I'd look at replacing the stock BOV. 2G BOV's can barely hold stock boost.

^^^maybe you missed it...he said he has a fmic with a greddy bov!

Also, if you are using the stock boost gauge, that thing isn't worth the cost of throwing it away. It is horrible at best. Hopefully you are using a good aftermarket gauge. If not, I would suggest getting one, along with all the monitoring equipment mentioned. This would be the minimum to make sure things are running relatively smooth!

Is your Greddy a real greddy or a knock off? I had a knock off Greddy and it leaked horribly.

It seems to be real, It has greddy engraved in it. I have an aftermarket boost gauge, but the reliability of it is kinda iffy.

Mbc would bypass the restrictor and if your boost guage is iffy at best i would invest in a better one if your changing the stock psi, could be very destructive to run to much without knowing.

When I was running just the waste gate actuator with the compressor housing I was doing 10 - 11 psi, and when I did the switch and connected it all up it still maintained the same boost level. ( in saying this I am assuming that my boost gauge is reading correctly seeing as stock boost is 10psi ish) My thoughts are that the solenoid is faulty and actually needs to be replaced if I were to want to continue with this "mod". I am not to worried about it. I thought it would be something neat to try while trying to fix other small things here and there.

By the way guys, I feel as if everything was lined up for me to remove the restrictor and put the solenoid back in place, I don't do anything that I feel would be pushing my car to the limit.

check for leaks and put a mbc on it

Im not to worried about it, I want to put a new front mount on it, new forge recirc valve and all that. I just wanted to try something. It didnt work I was just wondering if some one would know right off hand. A google search didnt provide much. But like I said, I am still in the early stages of this build. In turn I am not worried about making power at all. I am more worried with cleaning it up, and making sure its running good. Power can come later.

Not many know that there is also a restrictor in the hose between the compressor nipple and the y fitting that goes to the waste gate actuator. If yours is not OEM chances are its missing. I think that causes more pressure to be "seen" at actuator.

Check for this orifice and if missing get one. Boost on mine went up 3 psi.

Ah, see I dont have factory lines. I only have regular vacuum hoses running from the compressor housing and the WGA to the BCS

Thank you very much. That was helpful

Hope it helps. I do not know the size of the restrictor, I did not measure, but I did run without it to see what happened and lost 3 psi boost. That was with the BCS restrictor mod done.

Let us know how yours works out. I think the folks doing the BCS mod need to check this during the mod, as if this restrictor is missing the mod is pointless.

as found here completely pointless , nah im just gonna put a boost controller on it eventually.

I was thinking of getting a cheap manual one, I made one a long time ago and still have it I just dont want to blow up my car

I "improved" it recently with a different spring and a new way to restrict boost. I was thinking of running it inline with the bcs to see what happens.

I will just swap in a 6 bolt if I blow the 7 bolt

...
Why not just do it right, and dont blow anything? Ive ran a cheap $14.99 eBay MBC for 3 years, and no problems. Get a new Boost gauge. You should know how much boost youre actually running.

Is this the stock turbo you are on?

Yes stock turbo
