Default Garrett TMIC...change my mind

I’m currently in the market to upgrade my TMIC. I’ve pretty much narrowed it down to the Garrett or Grimmspeed units. I’ve searched and know a lot of people love the grimmspeed one but reallly haven’t found much info on the Garrett. I’m leaning toward the Garrett because of the price point. Remaining funds will be used for change pipe and tune. And it’s not like they are some no name company that puts out “eBay” parts. Anyone with good/bad experiences please reply. Thanks in advance.

Pretty length post on this here

Garrett is definitely a quality company, the main difference with the grimmspeed is the air diffuser and 1/8npt bung.

You can definitely find used Grimmspeed for the cost of the Garrett which is what I would and did do.

Short of that, it doesn't totally matter. You are going to make more power regardless.

If buying new, consider that if you buy from GrimmSpeed you're supporting a small, made in America business. Garrett is owned by Honeywell, and I am unsure of where their products are made.

Garretts warranty is 1 year, whereas GrimmSpeed has a limited lifetime warranty as well. So factor that in.

It may sound cheesy but this is the reason I buy Grimmspeed every time they make a product that I am looking for.

Another related benefit is that the Grimmspeed guys are awesome and are very active on social media (Facebook, Instagram, even these forums). If you ever have an issue with their products, they will take care of you, and they are all super knowledgeable about their products because they're all engineering geeks at heart. If you have an issue with the Garrett unit (a fitment issue, for example), who knows what kind of customer support you'll receive. You might get some nice-but-not-knowledgeable customer support rep or even worse, a bot.

Again, not to discredit Garrett as they are indeed a legitimate and very reputable company, but sometimes being too big can also be a disadvantage. With Grimmspeed, you know you are buying from a company that lives and breathes Subarus and nothing else.

Thanks for the replies. I have looked for a used one for a while. But it seems if your not one of the first to spot it, it’s gone. And @ $575 for the Garrett shipped it’s just so tempting. Might just have to bite the bullet and go new with the grimmspeed.

I installed my Garrett a month ago. Fitment is perfect and installation was simple. Difference in price easily paid for my tune as well. Well worth it.

Maybe marginally more than OEM, but not enough to amount to anything.

Didn't experience heat soak and stayed cool to touch after 20 min track sessions all day. Worlds better than OEM and seems to be working fine.

Ah yes, he didnt want all the benefits just enough. The ever important plastic shroud, must have important purpose on the track. Reminds me of the mask against the 0.003% killer virus. My bad guys.

Garrett was part of Honeywell, but got spun off into its own business a year or two ago. Garrett is the largest OEM turbocharger supplier in the world and the largest provider of motorsports turbos. I'm pretty sure this intercooler was designed by the team in Torrance, CA. Likely assembled at the plant in Mexicali, Mexico. They have major engineering centers in Cali, Michigan, France, Czech Republic, India, China, and Japan. And smaller application engineering offices everywhere like Australia, Brazil, Italy, etc. And manufacturing in Mexico, France, Japan, China, and probably a few other other locations.

The stock plastic shroud on the intercooler does mate up to the scoop duct on the underside of the hood. So if you eliminate the plastic shroud on top of the intercooler, you'll likely reduce the airflow through the intercooler as air is no longer ducted all the way to the surface, so air can bypass the IC.

And I'm assuming you're referring to Covid-19. Death rate is highly tied to age. Basically, the weaker you are and more health issues you have, which typically correlate to age, the more likely one is to die from Covid-19.

I got a Killer B TMIC and charge pipe for sale if you're interested. Should meet your goals and be way cheaper than buying either of the alternatives.

They've been great for me for the last 15k miles on my 2015 WRX and was laying down a conservative 383 to the wheels on Pump gas with other supporting mods. I'm going to for 425+ so I'm changing it up with some IBR stuff.

Youre not wrong but i was being sarcastic and referred to total number of deaths in usa (192k) over its population (350mil). Works out to 0.05% chance of dying from it, and this is not taking age into consideration but rather an avg rate. The numbers your charts reflect are most likely death rates among those positively infected w disease which is still miniscule, compared to say testicular cancer/breast cancer or any cancer in general, as one example.

Covid changes the Flow of air, thus resulting in performance loss. The ecu adds less fuel, because there’s not as much air entering the duct.
There’s a 0.1% chance, that this can happen on Subaru’s. But only if your age is 20-44 and don’t Vape frequently.

Performance loss is unnoticeable. But something to worry about nonetheless.

Garrett filing for bankruptcy, might want to think twice about buying one. (or there could be some great 1/2 price deals coming up)

Yes they are declaring chapter 11, but dont look for them to go out of business. They got royally screwed by Honeywell who gave them a parting gift of an asbestos law suit that they had nothing to do with. I cant imagine the largest turbo manufacturer in the world folding. Their new technology for eturbos, etc makes them invaluble to the industry. Their performance line is a big plus for enthusiasts, but their bread and butter is industrial an OEM, including their thermal group who makes the CAC's. They may spin off there CAC business though if it makes sense, but they'd be off keeping it to offer total systems.

Damn right it’s trumps fault!!!

Had he, back in February or March took covid serious we could have saved hundreds of thousands of OEM top mounts.

At least 200,000 OEM TMICs have been discarded due to this virus. In NewYork they even brought out boats just to hold them. There just wasn’t any room.

Now we’re facing another problem. Aftermarket TMICs were thought to be A-systematic. They’d get it, get a little stuffy, and DAM would go back to normal. New studies suggest this might not be the case.

Just do us all a favor..... Mask up
