BIG TURBO Questions!

[Fobio]

what is the biggest Mazda flanged hotside that can come with the GTX? I thought I've read that they/ATP now make a .70 a/r Mazda flanged hotside? or is the only options still the .50?

[EdgeAutosport.com]

the only option is .55 hot side

I aggree @eric@edgeautosport, we should become traveling BT installers for the MS3 comunity. We can be the makerz of teh fastz! And wear tights and capes!

You may be joking now, but I'd pay to have the experience of both you and Eric help me wrench on my car.

You can skip the tights when you come though. LOL.

what about the capes? lolol

I plan on getting a steedspeed mani for my BT build and I was wondering if there are any other turbos that can utilize the same DP-Turbo bolt pattern/flange (whatever its called) as stock?

unfortunately all they make that fit our stock mazda flange are the gt and gtx series which are great turbos imo. THe other route you could go if you want a different turbo is just get the t3 steed speed manifold and a custom v band dp.

[R3L3NTL3S]

gotcha thanks buddy. Just trying to figure out my options for my spring BT fest

[Boost_creep]

will any of the kits bolt up with a tmic? Corksport, if it matters.

yes direct bolt up

[shadesofgray19]

How does going with a T3 flange and larger hot side affect turbo spool compared to the stock flanged housing? This may lead me to go GTX3071 vs. GTX3076.

Anyone know if you can run a .82 A/R T3 housing with 3" V band on an MS6 in stock location assuming I had a T3 steedspeed mani? I'm not looking to go top mount as I already have a new V band ATP downpipe. Would the stock location turbo placement work or would I need the angled version of ex. mani?

[shadesofgray19]

Just saw your thread Eric Round 2 BT Build I guess it all is possible and can't wait to see the outcome. I wonder if my transfer case would get in the way.

[EdgeAutosport.com]

The spool will definitely be a little slower but honestly I dont think its anything to be concerned about. As far as getting that dp to work with that t3 hot side im sure it would have to be modified to clear your pto. If i were you I would look into the topmount kits they are the secks.

Also one last thing to order would be a 45* coupler 2''-2.5'' to fit from the turbo to hot pipe so its a direct bolt-up with your fmic This is another great question, you are correct the stock map sensor only reads to 22 psi but I still run it without a hitch. To compensate all you need is a accurate boost gauge and to up the boost an mbc (i run the grimmspeed) or an ebcs. DJ (djuosnteisn) runs the same 2.5 and he is planning for 30+ psi so really it comes down to personal preference

What's this saying?

What boost do you run on your setup? You saying over 22psi? with stock map?

[MS3KO]

Ive heard different ways to attach the oil/coolant lines. 1. On a gt3071 can you use the stock lines. I hear you can then others say you cant.

yes I run 24+psi on my stock map. Just make sure you have a good boost gauge.

you reuse the stock oil feed line with different banjos but I dont think you can reuse the stock oil return ive never tried it. You do reuse one of the coolant lines but it has to be bent to fit properly.

Awesome thanks! Ill just order the banjo bolt then.

[breakfstincluded]

Hmmm... let's say you plan to get a steedspeed mani and an atp BT.

Think it's better to have the EWG on the steedspeed or on the turbo since we have these options now?

nm I'll just do both and have them vent into each other until it explodes. Like gay dudes docking.

lol on that note is ATP's universal dump tube working out for everyone or is it something you typically have to get fabbed?

Wow that's the least unproductive thing I've written since the saturn thread.

Dang good to see you. I thought you died from a tragic case of a ripped colon.

If you plan on doing ewg. I would do off the manifold. That way you have less gas flowing out the tiny .55 hotside. Would be more efficient.

[VR10Speed]

I have a few questions.

On a stock manifold with ATP GT35R with the 38mm EWG Hotside when could I expect 16psi?

I only plan on running 16psi, I've been looking at the 3076 and the 3582 from ATP with the EWG Hotside. Will the 38mm EWG be able to keep either of these turbos from creeping over 16psi. I plan on using a 16psi wastegate spring as boost control, no MBC or EBC.

I know I will get flamed for only wanting to run 16 psi on a BT. I want to keep up with my cousins bolt on and pulley 2012 S4, and I don't want to use rod busting boost to do it, so I figured I'd just get a higher flowing turbo and keep the boost low.

Other mods will be catless TBE and CS ram air FMIC kit. I know I will have to find an inlet solution.

Well first off, the only turbos that EWG hotside will work with is the 3071 and 3076. You can't use it with the 67mm turbine wheel that comes with the GT35R.

Secondly, we will not flame you for doing anything that isn't completely stupid and even then, we'll help you understand why it might not make sense, we'll never "flame" you. That's what the rest of the forum is for,

To be honest, you might want to get a boost controller anyway. They are pretty inexpensive as it is. Are you planning on tuning once the new turbo goes on? 16psi from a big turbo is the not the same as 16psi from stock turbo. The EWG will be able to keep it from creeping.

[blkspeed307]

Hey JP did u ever find out if atp is making a Gtx version of the 2871?
Thanks
By the way will there be any problems running a Gtx 3071 with upgraded tmic, I know it will heat soak quicker than fmic but other than that any big problems?

Unfortunately, I don't think they're going to have one. It looks like they will only be doing this with the smaller 28 series turbos. You can run a TMIC with GTX3071 without any major issues. It works fine, FMIC just works better. That's all.

[blkspeed307]

Kool thanks

[VR10Speed]

Well I suppose that settles the 30 or 35 debate.

I use springs to conrtol boost, thats how I've done it with all the turbo cars I've had, I know boost controllers have their benefits but for 100 bucks I can get a few different pressure springs and I don't mind spending the time to swap them out.

I assumed everyone would know here that you just cant put parts on a car and not tune the ECU. The AP will be used to tune the car, I have a pretty good background in subaru/mitsubishi tuning using romraider and ecuflash.

Okay cool. And yes you would assume...but not everyone quite understands and I just wanted to make sure. Some people really don't understand what needs to happen. Not that that's a big deal but I just need to help them understand what's going on before they go and blow up their car. You'd be surprised....

Let me know if you would like to get that hotside or if you need the whole turbo. ATP will assemble and clock the turbo for you if you order all the parts together.

Besides the price, are there any more reasons to choose the GT3071R instead of the GTX3071R?

[JP@edgeautosport.com]

Not really. I'd say the only way it makes sense over a GTX is if you don't plan on pushing the limit of the turbo. It seems to take quite a bit of boost for the GTX turbos to show their real strength. Seems that they aren't spooling a ton faster but they flow much better at higher boost levels. So if you are planning to stay at or below 20psi, it might make sense to just go with the GT3071. But ultimately the GTX still flows more air.

Sorry the turbo section of our website hasn't been up guys, we're working to fix it now.

[EdgeAutosport.com]

GTX35R anyone?

ironically, these 2 posts answer pretty much my major questions
was looking to strap a GT3071 onto my gen1 3, and set it to ~18-20psi, with a TMIC
my goal is a safe and reliable ~360-380whp with a nice torque curve
still on stock engine internals, so didnt want to push them too hard

had been wondering if a FMIC or the GTX upgrade was worth it, but looks like it isnt... (dont really want the lag of a FMIC...)
just two questions, are you looking to bring out the mazdaflange'ed hotside with an IWG in the near future? and will i require a EBC for this set up?

IMO I would get a fmic with a big turbo, it wouldnt increase lag very much if at all. All drop in options unless requested are iwg. Personally I would run a mbc or ebcs with my setup but the stock two port can be used if you would like.

IDK maybe. It depends on what DJ does with his speed3 project...

[m249saw]

So do the smaller 28 series not fill a role with our car?

Im new to some of these turbos. How would a 2871 compare to the K04?

Im looking for faster spool more than huge boost, plus Id hate to have to sell my sexy new ETS TMIC

I think there is a role, just a small one. It's the guy that wants a good 350whp without going all crazy on a stock turbo. There seems to be less of these guys because the guys that are willing to get a big turbo usually end up saying, "why don't I spend $100-200 more for a turbo that is capable of another 50-100hp even if I'm not going to max it out". Then there's the guy on the other spectrum that says, "I'll be fine with only being able to achieve ~300whp with my stock turbo so I don't think I'm going to upgrade."

That's really why the 2871 hasn't taken off. It's also because the size of the motor. The 2871's are extremely popular in the 1.6-2.0l cars because of the car's inability to spool a bigger turbo as fast as the bigger displacement MZR or an EJ25 from a WRX/STI. Some people say a 2871 is too small for our car...I don't think so because that's like saying the stock turbo is useless and it's not. It's just hard for most people to justify spending the money on something that only gives about 50-75 more hp when they can pay barely more for bigger turbo and if they decide to, one day they can make 150 more hp.

But to answer your specific question, there's no doubt the 2871 is better than stock. It's dual ball bearing, spools about as fast, and flows more. You don't have to sell your ETS TMIC in any scenario. There are plenty of guys with stock and big turbo running TMIC.

[m249saw]

Thanks.

I guess that makes sense, only getting 50-75 hp more for $1500 ish.

So with a GTX3071 would the CP-e or equivalent Safe-Seals for the injectors be a prerequisite?

Also still waiting on a price for that Steedspeed Mani
