BIG TURBO Questions!

I can change to a testpipe and catback, but would like to keep the OEM downpipe, just bacause its a pain to take on and off every two years. I'm thinking of an GTX2861R IWG. What do you think?

Researching...

@JP@edgeautosport.com

So, stock downpipe with a 2871. Waste? Thoughts please

[Swinger13]

@JP@edgeautosport.com;

I ordered the gt2871r turbo for the MS6 from you guys and I wanted to make sure what exactly comes with the turbo. I have the coupler, the boost tap source for the coupler, 2 hose clamps, and a new gasket with 2 bolts for the oil feed line.

I'm thinking because I have the gasket and 2 bolts for the oil feed line I might be missing the oil feed line(s) themselves. Can you clarify this or do we reuse the factory lines?

Cheapest option...

I don't think it's a waste but at the same time, I don't think it's a good idea. Turbo cars need exhaust piping to be freed up more than a NA car. Back pressure would be bad I would imagine and I'm not sure the cats would like that too much either. You have to let a turbo car breathe.

Really informative thread. Thanks for the info!

I saw a guy with that IWG bracket from Cobb anyone else attest to it Im considering due to the fact I dont think Im savy enough for the hotside swap

Sorry for the delay. With the MS6s, you reuse the factory drain line. It should come with some stepdown studs to mate the factory line to the new turbo.

Yes, it works. But get the longer Subaru bracket if you have a big turbo. The hotside swap isn't hard at all but you need to clock the turbo correctly which isn't that bad with just the hotside.

I was looing into boost controllers and was wondering is it better to go mbc or ebc with a bt if im tying to reach 400+ hp. And witch brand would be better to go with.

ebc imo.

Having control over your boost curve is pretty nice once you get to those power levels. It can nake it a lot easier to manage wheel spin in lower gears.

As far as brand goes, im pretty sure that they are all just rebranded mac solenoids, so there is really no difference.

[mrsmith]

And the aem tru boost is a mbc with a digital controller right? and would I tue it with the ap. if that's the case im just going to go cobb.

It's really your choice. I use a MBC because it's super easy and I can go give it a couple turns and get more boost just like that (if the tune allows for it). I personally like just choosing my boost level then getting there whenever I stand on the throttle. Some guys like tuning boost per gear which is cool too. It's just preference for how you like the boost to operate.

The AEM Tru Boost is an electronic solenoid just like the Cobb except it's not plug and play like the Grimmspeed and the Cobb.

Do you guys have a similar package that CP-E offers? with the vband downpipe and manifold and choice of turbo, with lines/gaskets/studs etc included? and the EWG dumping into the downpipe? Really want all that with a 3076. and I'll need a FMIC too, preferably the UR with the slim crash bar.

Other than CPE we don't have anything like that. Not sure if you realized but we do sell the CPE kit in whatever configuration you want.

[ABolewski]

@EdgeAutosport.com; didn't realize that! Only poked around on my phone for the most part. I'll definitely check it out a little more on the Mac. Thanks

Looking at turbos and have a question. With the gt3071 does the anti surge porting option help with the boost creep and what exactly is the benefit?

[thered rocket]

If you are going to do anti surge porting on a gt3071r just get the gt3076 it already comes with it. The cost to do the porting is about the difference in turbos If I'm not mistaken.

That's true but does it help with the boost creep or did that issue get fixed?

[Fizzyb]

Anti-surge porting is to do with the compressor surge when you let off (that should escape through the bov. The rear housing that causes boost creep I believe is still an issue even if you pay for the anti-surge porting. I was of the same belief as you though JP corrected me when I originally started looking for my turbo upgrade.

@EdgeAutosport.com; I can't find an option for a gtx3076 EWG do you sell them??
I may just be blind

Okay. Thanks for clearing that up. And all you have to do is port it and it won't creep correct?

[Davsetz]

Read this it takes more then porting although porting helps..

Not necessarily. It depends how well you flow intake and exhaust side. But porting and a good high flow 3" cat will stop creep.

Damn I have everything on the list that causes creep. Would my best bet be going ewg instead of switching out everything I have?

You don't have to replace everything. You must make the call...ewg is more costly especially if you want to re route to DP to be quieter and it's a little easier to tune.

Iwg is set for the get go, but tuning can be a bitch. The only way to know if you'll creep is putting it on. If you do...buy a 3" cat and weld it into the DP and you'll be fine.

Ok thanks for the help.

[Swinger13]

@EdgeAutosport.com; is it possible to order just turbine housings from you guys? I may have future plans to get a hotside for the GT2871R for the mazdaspeeds. Also if you are able to get JUST the hotside? I know there isn't a GT28 EWG hotside so is there a service you can provide where you can shut the IWG hole via welding or some other method?

[EdgeAutosport.com]

We do sell turbine housings by themselves. Just let me know what you need. We do not weld the iwg shut, but you can get this little guy (Cobb Tuning IWG Bracket) which will do that job for you. Let me know if you have any other questions

can you PM me a quote price for the bracket and the GT28 hotside mazdaspeed version?

[Voltwings]

Sorry Edge, but I wouldn't recommend that bracket at all. Maybe its install error on my part but I had mine come loose 3 times on my 3071 and I ended up with no boost, and it is a BITCH to get under the car and fix it. The problem is it doesn't cleanly bolt to the turbo (or at least not mine) because one of the coolant hoses is in the way, and then, the arm is WAY too long to hold the flapper shut so you have to trim it back a bit ... its just really not worth the effort man, I threw mine straight in the trash when I went EWG.

Agreed the Cobb bracket is junk. @Last_Loser; can attest to that!

Thanks for the info. I was questionable about that actually, it works great on the k04 as I've helped install one before. I can adjust my WG no problem on my gt28 installed but to take the whole wastegate bracket off it's actually a 3 bolt bracket and I had to take my turbo out completely to do so when I not knowingly installed my turbo with an 8 psi wastegate when I ordered 14 psi.

I would have to see pictures of the bracket installed on the GT28 before I invest in it

[bhamitgeek]

@EdgeAutosport.com I have a question for ya. I am looking at the GTX2867R kit. I wouldn t have to change the TIP out with that kit since I have a JBR Stage II correct? as soon as my internals come in I will have the test pipe on and internals. I should then pretty much need just to upgrade to the IC.... would the CP-E IC work just fine with this set up?

[NCspecV81]

Jbr doesn't have an intake to fit the 3 inch inlet. I posed this question in the jbr forum. You'll either need a aluminum version with reducer or a new intake. I chose the htp 3 inch. I'll be using the cs tmic with the same turbo so I hope the cpe version would be fine.

We have just recently been made aware of another GTX2867 option that will allow you to retain the factory size turbo inlet pipe should choose to do so. It will also fit the with factory intercooler configuration. We will be posting up details about this very soon
