SBR up pipe w/ EWG

STIfreak7 · 08-26-2006, 06:36 AM

Hey all I have a TXS catless TBE and a SBR up pipe with tial 38mm EWG coming next week. I am going to run the stock turbo w/ stock boost still with the EWG to fix the boost creep issue. Yeah I know its alot of money to just fix the boost creep issue but in the long run I will be glad I have it. I install question is:

What recommendations do you have for disabling the stock IWG. Slowboy racing suggests welding it shut. But I was hoping for something less permanent. I have been told by one other running the same set up that he used racing wire and wired it shut. In my mind that would work but I would love to see some pictures. Any pics of the vac. line routing for the EWG would be great also, or would simply plugging the same line from the stock IWG to the EWG work?

Thanks for any help.

Welding it shut is the only option.

What Lb spring is in your EWG?
If it's the 1 bar spring then you can just run it straight off the wastegate and be fine.

Suppose to come with a .9bar spring. I would feel so much more warm and fuzy if it was actually called 1.0bar, but .9bar would work fine, right?

When you say straight off the waste gate you when with NO line on it, just using the spring, correct?

Welding the wastegate shut is the only proper way to do this that I know of.

Are you sure the SBR uppipe w/ EWG will work with the TurboXS exhaust? I was looking at the Element uppipe w/ EWG plumbling and Phil told me that the TurboXS downpipe would not work with his setup w/o some serious modificiation (read: severely bang the hell out of it with a mallet to make it fit) to the downpipe since it's so large.

I used to have the TurboXS exhaust myself and when I went to the 20g I wanted a EWG so that meant losing the TXS downpipe or beating it in with a mallet... I ended up going with the HKS downpipe instead of beating up the TXS one

This is with the Ultimate Racing up-pipe, IDK about the Slowboy one, but I'd be shocked if it was made to work with the TurboXS downpipe.

You would run the line straight to the bottom nipple of the Tial EWG (bottom meaning the bottom when it's installed.. in other words the nipple closest to the ground).

I have the UR racing EWG uppipe on my WRX and also wanted a less permanent solution to disabling the IWG. I only did a small weld on the outside arm of the wastegate as opposed to welding around the entire flapper inside the turbo. I have been running it this way without issue for a longtime now so it seems to work fine.

I sure hope it fits. I asked the question before I ordered it b/c I knew the ultimate racing pipe had fitment issues. According to slowboy racing themselves they said the up pipe fit with all bell mouth dp's.

I think I'll try the weld on the IWG arm and hope it works. That will be a little less permanent.

Anything else I would have to do with the vacuum line or just get a little longer one and run it from the same T fiting to the EWG? The Tial EWG has two line fittings does it not. One on the end and one on the side. Which one do I put the stock line on? Do I just cap the other one?

You don't have to cap the unused nipple on the Tial EWG.
You're going to want to run the vac line down to the bottom nipple of the EWG, while the top nipple is just left alone.
When you first take it for a spin if it doesn't open at .9bar then it's not hooked up right, but if you see it go right past .9 bar and not open do not press your luck by giving it any more throttle or else it'll just keep building boost

Then your engine will go bye-bye.

i used something called safety wire, its used in race cars to hold the IWG shut . . its worked perfectly i also took the vac hose off the iwg as well . . .

make sure you take that little hose off with the white dot on it( the vac line with the pill in it) otherwise you will run more boost then 14 psi

cnstman · 08-27-2006, 07:53 PM

please let us know if the SBR pipe works with the TXS bellmouth. thanks!!!

Welding isn't the only option when keeping the IWG shut. I made a bracket that is "L" shaped and mounts to one of the points where the actuator was. I still have yet to install my set up(need a few more things) but there was a guy on another forum with a picture of how he did it.

I don't mean to hijack...but I have a couple questions...when routing the line from the compressor to the EWG you have to remove the restrictor pill, correct? Is running the EWG on Cobb Stage 2 just off the wastegate pressure ok for like 2 months until you can get tuned?

02wrbrex1 · 08-27-2006, 08:40 PM

just wondering couldnt you just get like a 30psi spring for the internal wastegate so it wont open thus keeping it shut? just a thought..

jason bouchard · 08-27-2006, 09:42 PM

the easyst way to keep the iwg shut is to get saftely wire and wire it shut, if you dotn want boost creep or lots of extra boost( blown motor) ten take the restrictor pill out, its easy and near the vac line nipple on the turbo cold side, near the turbo

02wrbrex1 · 08-27-2006, 09:59 PM

do you have any pictures of where the safety wire would go?
