Some Pictures of my Open Dump 02 Housing
Here is my mod list

I run a MAC solenoid which is controlled through the stock ECU. It is basically the same as the GM solenoid, only it is much higher quality and reacts faster.
I actually used to hold more boost but since I have done better exhaust and intake and all that my motor flows more air making it harder to hold boost at higher RPM's

ouch... how much welding did they have to do ? it would probably cost me 20 plus the cost of the O2 here..... i just need better pics and need to see if there was any internal welding you had to do

ok... that shouldnt be too difficult i wouldnt think, just some fabbing... and then making the pipe. Im going to start working on this. I will use my stock O2 as a template... thanks for the reply
The open dump setup WORKS. It will add power, especially torque when the boost hits. To have this mod done correctly though, you of course have to separate the wastegate chamber from the turbine exhaust chamber (common sense really), but Im sure some people would just cut a hole in the 02, weld on a pipe and call it a day.
Dudical26...will this work with an OEM LICP? Any idea? I'd be extremly interested in buying an o2 housing (eBay o2 housing?) and sending to your friend to do this for me. As long as it works with an stock LICP.... If not, well, I guess I'll just upgrade my LICP
It will probably work with a stock LICP or any other LICP for that matter. But the fitment is going to be custom. You would really have to take the car to a welder to do custom work.
