Universal Product This item is non application specific.
Please verify compatibility before purchase. May require some modification for proper installation.

If you’re looking for a reliable external wastegate that has been engineered, tested, and proven to give you reliable results, then you may want to consider a Tial unit. External wategates can endure extreme temperatures, and because of these reasons, the Tial unit has been crafted from fine alloy materials to provide the user with longevity they can depend on. 

Boost can be controlled from two top ports, as well as three bottom ports.  At just 3.7” tall, the Tial 38mm MVS wastegate is one of the most compact external wastegates on the market. This Tial unit will come supplied with all the springs, and some wastegates come provided with pre-installed springs installed by Tial, so you may want to verify which springs are installed before installing this part onto your car.

Ok first thing, the packaging was rock solid, props to Tial for that. The gate itself was a great piece and have had no issues with it at all. Only reason i gave it 4 stars is the v-band clamps they send you with are GARBAGE. Id prefer a standard v-band clamp over the weird ones that were sent. Still works great though.

Hands down my favorite performance mod ever to either of my subies. I absolutely love loudness, when my P&L quadtip and catless DP didn't satisfy me anymore this did the job. Puts a huge smile on my face every time this thing opens and I find myself giggling like a schoolgirl, I stuck with a EBCS because I like the sound of wastegate flutter rather than just open or closed you get with a hybrid MBCS setup

Installed the EWG with the Grimmspeed up-pipe in a couple of hours (drive on ramps aid in ease of access). Had the car tuned and it rockets to redline and max boost! Yes, this sound like you're taking off in a rocket, but potential threats will most likely wet themselves before messing with you!

I needs an EWG since my boost creep couldn't be tuned out in my 5th & 6th gears so I added this onto my GrimmSpeed up pipe and had it retuned along with a few other mods. I love the scream it makes when I go full throttle & I have no worries of over boosting. I build & hold boost better. If you don't like loud I'd suggest you reroute the dump tube back into your down pipe. I installed it my self in less than an hour with a jack, & simple hand tools.

QUESTIONS & ANSWERS (16)

  • AnswerQ:    28 days ago

    Will this fit my 2004 wrx stock turbo if not what items will I need to make it fit?


    • A: You will need an uppipe with an external wastegate flange (like what Grimmspeed offers). You will also need a bracket to block off your stock internal wastegate. Keep in mind that you will also need a custom tune to run an external wastegate setup.

  • AnswerQ: 2006 LGT  Sheepdog 5 months ago

    Will this fit on a stock turbo for a 2006 LGT?


    • A: This will not fit on the OEM turbocharger. OEM Subaru turbos use an internal wastegate. To use this you will need an uppipe with an external wastegate flange and other accessories.

  • AnswerQ: Second tune?   travisallen948 5 months ago

    If I have a pro tune on 20 psi would I need another tune after adding an EWG


    • A: Yes, an EWG will require a tune.

  • AnswerQ: Wastegate size  randice12306114 7 months ago

    2013 wrx stock turbo. Would you run a 38 or a 44mm ewg for this application?


    • A: The 38mm wastegate should be sufficient for your application.

  • AnswerQ: Psi  Henry's04FozzyXT 1 year ago

    So would changing the springs change the psi in correspondence with that chart?


    • A: The spring would effect the wastegate's base boost level but if you are using a boost controller that will determine it depending on setup.
