Anyone ever run this with much success. Im a little scared of introducing more possible failure points. Id imagine someone would run nice locking hardware like stage 8 on both sides and possible brace the turbo for double reassurance. On the other hand I think its a chunk of **** and is asking for leaks and cracks as it causes the turbo to have more leverage. I wanted to use this on a cheap shitty type build in the mist. Ive also considered making my own for more strength.

 

I thought about doing it at one point but it seemed like a recipe for disaster, plus I bet it would make even small turbos have clearance issues.

 

Yeah thats what puts me on the fence. They have them in different angles for clearance. Id just rather weld this POS as far as bracing than try and weld an EWG on a BEGI manifold I have.

 

This guy ran one on his 280z no issues so far. Thats what got me considering it.

we stretch our studs as is, this thing is just begging for problems.
also you'll hit the frame rail
and even if you clock the turbo the downpipe routing is going to suck.

 

True true. Oh well I'll just sell the BEGi log and drop some money on the EWG log BEGi sells

 

You'd be better off getting an externally gated exhaust housing I believe for it to fit properly.

 

If I was crazy enough to try this, I would buy a new exhaust housing.



Special Turbine Housing T25-EWG-44 : atpturbo.com

T25 inlet flange and standard Garrett 5 bolt so it'll fit most OTS Miata Garrett kits out there. Only available in .72 A/R and its 44mm VBand for a Tial EWG. It would stick out the top so no framerail issues, and the dump would be fairly easy to mate back into the downpipe, provided you don't have the FM cast elbow or something.

I'd be tempted to try this if I got a hold of a cheap 2860RS or a 2871 as the smallest thing it will fit is a potato. I'm not sure why you would want an EWG on a GT2560R or smaller?

 

Ive welded a bunch of external gates to exhaust housings.

I've been told that sticking an EWG on the housing like that is highly disruptive to turbine inlet flow.

 

All of the modeling I have seen shows otherwise.

Real life results shows not loss in spool, or hp at the same boost and really really amazingly stable boost control.

With a 17psi spring on that particular one we never saw anything further from 17psi than 16.8psi. I have done a few all with excellent results.

You have an FM log manifold? Aren't you able to mill the FM logo off and bolt a EWG right onto the manifold?

 

There is no room for that spacer with a FM mani.

 

I got a spare BEGi one and a FM one on the car in my sig. The EWG won't fit on the logo area. viperormiata tried it with a 38mm and it hanged of a little on both sides. If I could trade for an older fmII manifold I could mount it in the bottom. I would also be willing to purchase one but they seem to be hard to find. A on craigslist has one right now but he wants a lot more than I want to pay.

Whats the deal with putting one on the DP? I know a lot of guys do it on Grand Nationals as well as some DSM guys. What if I did something like this. I guess I would just leave my internal flap open or removed and this way I wouldnt have to run a screamer pipe.






EDIT: Nevermind I dont think that will work

 

Its apparently crap anyway.

 

I think its junk.

However,
a buddy of mine is running a setup like that on his BP and it has held up and worked great for like 5 years now. he completely gutted the iwg, hogged out the port as large as he could, and running a tial 38 vband ewg on there. it still has the divider in there, without one it wouldn't work at all. this is on a evo 16g

I still don't like that setup though.

why not just sell your manifold and have abe make you a proper one? you'd be surprised at how reasonable his prices are. he can do a "fm/begi style" tubular for only like 100 bux more than the basic log

 

Thats what it looks like Im gonna do. Not worth the risk involved jeopardizing the current equity I have in my current manifold.


Edit

Probably ask for something like this

Cast manifold? Cast HKS solution. Too bad the image from the Gurney Eagle MKIII is dead since it used the EWG-turbine-mount solution. Best I could find is this:

 

The most frugal way to go about it is to Just get your manifold customized to support a wg flange. Weld or bracket the wg flap shut. Port polish the exit area if you are worried about flow or boost creep... This has been done countless times over in the fwd Sr20 community... And those cars have more constraint issues than a miata for turbo. IMO go with a vband if you can. I can't ell you how many times I've removed my wastegate to swap springs.

There's nothing wrong with that adaptor, but there are too many bolts, nuts, etc and that just screams frustration IMO. Unless it's a bottom mount setup I wouldn't bother.

If you want external gate, do it right and you'll thank yourself later.
