Unfortunately, guys are just going to have to wait for aftermarket parts to be developed and start trickling out. I'm excited about the chassis rigidity and twin scroll setup. Disappointed in the heavier curb weight. Overall, I'm a fan.

Getting ready to swap a Dom 1.5XTR onto my 2010. Maybe in a few years, I'll pick up a new WRX though.

and the bread and butter " I " mode allowed me to hyper mile
myself to average 34mpg while on freeway in the 2015 WRX...

It was an experiment to see how high mpgs I can get on the freeway,
but the downside was it being super boring since I did not use HVAC/radio
to save power...
I was even driving behind larger vehicles for the "drafting" effect.

From what I saw, the mounting points on the throttle body side are identical to previous years, the other mount for the PW is off of a trans bolt, I don't see it being to far fetched. The one thing that would concern me is mounting the splitter.

Most likely I'll just be doing the bullet proof mod to the stock intercooler, which will still be the same kit, since only the width of the intercooler has changed.

Jason is one of our project managers here at Mishimoto. He worked several years as a Subaru technician and has been an avid Subaru enthusiast for quite some time. His previous DD was a last generation WRX so he is able to provide a direct comparison to his experience with that vehicle.

As mentioned before, once our vehicle has been reassembled from the tear-down we will be providing an in-car review of the suspension, power, and CVT features. Stay tuned!

From the looks of things, fitting a previous generation cooler with the factory style hot-side connection will be quite a challenge. I assume we will begin to see owners attempting installations soon. Our team will be tackling new intercooler development as well.

Also, haven't seen anything on this yet, but how does the size of the turbo compare to the outgoing model?
Although we will be developing several CVT related products, we have yet to determine our entire plan for testing the system. I agree, it would be very interesting to see how much power can be put through the transmission before failure as well as the effect of rigorous driving has on fluid temperatures.

The turbocharger is completely new, a twin scroll design. It is a Garrett/Honeywell GT2259!

I had thought about that mod for a short time for my OEM TMIC before I decided to buy a new one. Research "pressure drop" if you haven't already. The PW core has something like a .5 psi pressure drop while the OEM unit is something like 2psi drop at approx 20 psi. It basically means you have to push the turbo harder reducing it's thermal efficiency and it's compressor efficiency, heat soaking the OEM TMIC earlier and easier, and causing the resulting timing pullback as you would encounter knock sooner.

The OEM TMIC really needs to go when going beyond stg 2 levels.

I feel like the wrx doesn't have as much power as it should.

Do you think a good tune without any mods would make a huge difference on the 2015?

I would imagine the 2015 WRX will be no different than previous models as far as aftermarket support is concerned. It won't be long until there are a few higher horsepower vehicles running around. We are already working on some components that should provide a nice increase in power.

Mishimoto,

There have been a number of questions regarding the wiring in the side mirrors for the WRX. Specifically are they pre-wired for the STI side mirrors with built-in turn signals. Is that something you guys can check?

Thanks!!

Any guesses on if the DI setup will flow enough for E85? Or if the STI dual-zone climate control can just be dropped in to the WRX?

Aftermarket companies need to be very careful when designing parts and must bench test the OEM part vs the aftermarket "solution". Just because it looks ugly and restrictive does not mean that's really the case and just because the aftermarket part can flow way more air doesn't mean the motor can do anything with it.
I think (or at least hope) that everyone knows aftermarket parts by themselves will net very little horsepower compared to stock. There's a bunch of (hilarious) videos by Mighty Car Mods on YouTube that debunk the performance gains of adding JUST a cold air intake, an intake manifold, etc.

However, as you mentioned, the manufacturers spend millions on R&D, BUT, their focus is a combination of performance (HP, TQ, handling), NVH (to increase the marketability of the vehicle outside of the "hardcore" group), reliability (to reduce the amount of warranty claims), and emissions/fuel economy (since there are increasingly strict emissions & mpg requirements being pushed by governments around the world). So yes, with those constraints in mind (to deliver a product that meets all four), aftermarket parts will unlikely do better than OEM on meeting all four requirements. But, aftermarket parts usually only try to address one facet of that, which is obviously performance, and hence, the other three go by the wayside. This is the reason why aftermarket is better than OEM: they're highly specialized. It's the same philosophy of how our society works. We let doctors be doctors, engineers be engineers, mechanics be mechanics, etc. Back in the day, your barber was your dentist; that didn't work out so well, since he was the jack of all trades, but master at none.

Furthermore, the OEM parts are designed/tuned to be optimized for exactly the HP advertised. They will, however, be restrictive/unsuited for higher HP (above the advertised value). So, aftermarket parts will truly shine when you couple them with a suite of other aftermarket parts and tune the engine (turn up the boost).

That's basically the aftermarket dogma explained in a nutshell.

Thats why mods without dyno evidence always scare me off.

This is true for all mods...less those turbonators, I mean...who needs a dyno with those, its obvious it will give you 500HP and 30 extra mpg. Duahhh

Interesting. We have yet to pull off a door card or any of the interior components quite yet. I will see if this is something we can do quickly to grab a shot of the harness.

Great questions here! I do not see that the FA20DIT has been run on E85 quite yet, so this we do not have an answer to quite yet. Our current development is based around improving cooling efficiency and basic bolt-on performance. We have yet to dive into the fueling system.

I would have my doubts about the dual zone system being a drop-in replacement. We will check into this a bit further and report back.

Hey guys,

Our next video installment is now available! In this one we cover the exhaust system components from the turbo housing to the exhaust tips. Check out the video below and the gallery of images on our Engineering Blog!


Thanks!

Great as always! When will the "so you want to build a WRX from scratch" video come out? LOL

I remember with my Corsa cat back exhuast on my Pontiac G8 GT not only did it sound better and flow better, but I cut a significant amount of weight from the stock oil drum mufflers, it appears the WRX can see some savings here also.

The only thing is, it's already front weight biased so maybe the weight reduction should be focused on the front.

Thanks for watching! We have a ton more topics to cover so stay tuned for more.

You are correct in assuming the exhaust upgrade should reduce weight. The factory system is not extremely heavy but freeing up a few pounds should be possible.

We would recommend against using wheel spacers to reduce the wear on the already weak wheel bearings. That being said, a 10mm-15mm spacer should do the trick.

Ok, good...people laugh, but 10 pounds here, 20 pounds there, etc....its starts adding up.

Dear Mishi,

1) It's awesome seeing a company this devoted to customer service and being this involved with the community. I can only rattle off a handful of names that will do that. Go buy whoever had this idea a beer for me.

2) Haven't had a chance to even look at my '14 hatch's radiator yet but what's the fin design on the radiators along with the # of cores? I'm assuming they're running two cores of some sort but I'd be interested to see if they're running a louvered, wave, staggered core....etc. I'm sure you guys have that part under control though

3) If you guys need an extra engineer that has a BS. in EE and a BS. in ME, with considerable heat exchanger design experience...let me know....please? Looks like a seriously cool work environment!

Keep up the awesome work, I'll be waiting for the next video.

I'd be curious if you could maybe do some interior measurements? Looking specifically for seat size, width of seat, width of upper seat, length from edge of seat to the pedals and from interior b pillar to b pillar.

Reason I'm asking, I'm a bigger dude and coming from a 2013 Legacy I want to see if I fit .

1. Thank you very much!
2. The 2015 model uses a single row radiator at just 20mm thick. Despite this, it features a very dense louvered core. We will certainly be developing an upgraded component to handle additional heat that comes along with engine upgrades.
3. Thanks for the offer! We are always accepting applications. Feel free to shoot me a PM regarding this if you have a moment!

Absolutely! Check out the images below for your measurements. The one measurement I could not obtain was from the seat to the pedals. Our car is a bit dismantled and the electrics are not currently connected. Once we have everything close to being back together I will get this for you as well.





B-pillar to B-pillar measurement: 51"

Thanks

Default Yo ...

I agree w/ previous comments such as nice summary videos and quick direct follow ups to questions. I actually just read through the entire thread and watched all the videos. I'm still debating between a 2015 WRX Limited w/ CVT or 2015 STI Limited.

1. You've already touched on the topic of the CVT. If your not planning on changing internal or updating software ... what are you planning to do to make it "higher" performance? Why would the CVT be slower 0-60 as most DCT are faster than their manuals counterparts ... assuming the comment from the most recent DRIVE Performance mag on how the CVT is competitive to DCTs?

2. How do the LEDs compare against the 04 STI HID or any recent Subaru HID? I'm hoping brighter, whiter and longer throw however I'd heard conflicting stories?

3. Isn't the 2015 STI basically the same as the previous few years so really no huge difference in engine and drivetrain except for the many suspension upgrades?
