Ewg on down pipe??
Never mind figured it out :p

Won't work. Please look up how a wastegate works and come again. You need an outlet for the gases BEFORE the exhaust gases enter and exit the turbine.

Your exhaust manifold must facilitate an external wastegate first of all. if you want your ewg to mix with your regular exhaust you'll need to modify the downpipe as well so that the ewg vent into the downpipe. If you want to do vbands and external wastegate you still need to block off the internal gate port. Some people weld them shut. You could vent your ewg to atmosphere so you could use your old dp but still would want to make some sort of exhaust pipe for the ewg. your other option is to replace the arm and flapper and run an IWG. sounds like you haven't thought our your turbo setup very well. go back to the build threads and read and learn more. If you're not planning on running an ecu then forget anything i said. If you are planning on a stand alone ecu I recommend focusing on learning to tune your car and read as much as you can. don't get in too deep and waste a bunch of money and be upset about it. It sounds like your headed down that road atm. don't turbo till your ready to turbo. it's more complicated then just buying parts and bolting them on. |
If you run a Godspeed turbo, you don't need to get a standalone because its not a Garrett turbo.

I have a my Ewg mounted after the turbo.

You also have it mounted backwards.

Lol!!! This is the silliest thread I have ever seen!

P.S. what car is that in/going in? Turbo mounted opposite from normal NA/NB mounting and dipstick on other side? |

Besides you apparently having your wastegate mounted backwards (as referenced by the orientation of every other wastegate I have ever seen), you also apparently have it attached to turbine housing at an internal wastegate location. That means that you indeed have your wastegate mounted BEFORE the turbine wheel (correct), although placement is not straight or ideal. Boost creep bro?
P.S. what car is that in/going in? Turbo mounted opposite from normal NA/NB mounting and dipstick on other side? The waste gate is post-turbine, between the turbine and the muffler. No boost creep. Its an old IHI vj-23 ball bearing turbo, going in a protege 4wd. If I can get photobucket to accept more pictures I will post up better pictures. |

Here's a crappy pic. You can see the flanges for a ewg (I'm assuming) on the dp.

okay, and?

I have this on the way (as you can see in the pic of the current setup I don't have this whole assembly)
So disregard the whole ewg idea. The flanges are going to be cut off and blocked and the dp is getting a vband flange welded on https://www.miataturbo.net/attachmen...ine=1359556439 |
I just don't get why they'd put those flanges on for an ewg... Because eBay?

no, it's not.
The OP originally was asking about setups like this, or I believed he was. can't remember or see the question any more. |

I can't tell if you are joking or not.
The exhaust flows into the turbine housing and what ever gases are bled off flow through the wastegate. So if you are being facetious, true it is not in the flow path of the turbine. It would be physically impossibrule for the wastegate to be between the turbine and muffler, but able to "bleed off" gasses around the turbine. It's not semantics, it's not a technicallity; it's simple NOT behind the turbine. It's infront of it. Route the damn tube all the way to the tailpipe, it's still in front of the turbine. |

The flanges they have on the downpipe are perfectly fine. That manifold/combo is designed for a turbo using the tradition "Ford 5 Bolt" style turbine outlet and will bleed off enough gas through the hole to work well with an external waste gate. People have been doing it that way for years and years. Don't make the mistake of thinking that is "after the turbo" because it's definitely not. That will bleed gases pre-turbine, not post turbine. That setup uses the same style waste gate hole for the turbine housing that most internal waste gate systems use, this just happens to have flanges for an external waste gate that will operate it vs. the traditional can and arm. |
