3.3TT Mishimoto's Stinger GT Intercooler Kit R&D Thread

[xot1]

@17th_Letter, what do your IATs look like for daily driving? I'm pretty sure you're the only other person with the Mishi kit installed right now. Every IC will heat up a lot when stopped for long enough so I'm more concerned about what your temps are when at cruising speed (30MPH and up).

I did not install it yet. Won't be able to install it before the end of the month, unfortunately.

Sorry, that was directed to @17th_Letter. I probably should have worded that differently. I was basically replying and tagging 17th letter to get their input.

Haven’t completed the install yet, but unfortunately the AEM intake rubs.

I have no idea, im not running anything that would let me monitor that.

Hey Guys,

Just jumping in here to address a few things!

Hi Mishimoto

I just received the intercooler and weighed it.

31 lbs core only.
32 lbs with the little brackets.

Your datasheet also says 26 lbs:

So just want to start out and say that we're definitely not trying to fudge the numbers on this one. I did the weight comparison myself for our production sample and stock core what seems like forever ago in April. Lots of different variables at play here, BUT I believe that we still have another intercooler core in house, so I'll check on that and confirm the weight spec tomorrow if that's the case.

Sorry for the discrepancy, guys! I'll make sure this is updated ASAP.

After driving around the past couple days my IATs are definitely up during “in and around town” driving compared to what they’ve been. It builds way faster in traffic now than pre-Mishi aftercooler.

I’ve been watching IATs very closely after installing @Rakker ’s snorkels and then the added benefit after I cut out the outboard cells in the non ‘smart cruise control’ GT grill, fully exposing the snorkels to the outside air. I had this mod in the back of my mind the whole time wondering if I’d see even lower temps.

I’m going to order a sheet of this heat reflective tape, pull the charge pipe and give the lower portion behind the radiator a wrap. I doubt it was by accident Kia added all that tar-like insulation to the OE charge pipe. View attachment 51280

Thanks for bringing this to our attention! Our engineering team has a few leads on what could potentially cause this, and they're investigating it ASAP. I'll be sure to keep you guys in the loop on what we find.

Couldn’t help but to start disassembling the front bumper and completely forgot about my crash beam being completely different than you guys. Taking it to the shop to have them trim the extras out.

Let us know how it looks, and the process the shop needed to take for this modification! This would be great info to update our international websites.


Thanks,
Nick

For the crashbeam fitment, Wagner was the first company to make this mistake. Mishimoto obviously didn't know either.

Companies aiming at a global market must know the difference. Our crash beam has two extensions towards the bottom, while the US version has not.



We have these two extension because a bottom piece attaches to them. I don't know what is the exact purpose of that piece, but US cars don't seem to have it.(cost reduction? safety regulations?)

Good point and this is going to be a problem...

Just cut the extensions. That bottom piece isn't needed. Wagner used it to make an air guide but there is no such thing in the Mishimoto kit so I'll just cut mine.

I took mine to the shop to cut them. If you just trim the weld points it will pop off.

So, we did know that there was a difference from photos and part numbers, it's just pretty difficult to get a hold of a non USDM crash beam here in the states to get a good look at. We have some contacts in AU that were kind enough to send us some details recently on what all needs to be trimmed and how, just to make sure we weren't instructing you to chop off anything critical.

Also, I was able to do another weigh-in on our intercooler and confirming that the 31lbs. spec is correct. It's hard to pinpoint the reason for the discrepancy, and again, I apologize that it happened, but thanks for bringing it to our attention so that we can get it updated ASAP.





Also, just as a heads up for those of you in Australia, our blow-off valve adaptor is now in stock and ready to ship in that region!

Thanks,
Nick

Ordered Aug. 3rd
Arrived today.
Just got home and here is the first photo.
Now to unload.
Thanks @Mishimoto im excited

I think you guys should consider revising the upper intercooler pipe for more clearance, it is too close for comfort on most aftermarket intakes and is touching the AEM intake.

Also, are you guys planning to make an intake system for the Stinger?

Some of us asked this several months ago. It sould be available for pre-sale by now.

Finished the install, the pipe touches the fan shroud as well unfortunately.

anybody attempting this on there own and without a car lift, remove the crash beam before installing the intercooler, way easier to do.

car feels notably faster, intake temps while driving are better than before when compared to ambient. Haven’t tried stop n go yet.

You had no intercooler before?

Was on OEM, first time putting an intercooler.

Thanks for the info. I'm glad to see that someone is getting better temps than stock while cruising. I'm looking forward to hearing the results of stop and go testing.

How could you wait so long? Vs stock the car should definitely feel faster

Just finished installing mine. All went well, just missing skin on my hands here and there. Although, I ran into difficulty with the merger piece. it took some time and effort get it work/installed. Has anyone experienced that? It felt like mine was 1/2 inch winder than stock one.
