2017 Red Manifold
 

So I was at the dealership to buy my new 17 brz and I noticed the show car didn't have a red manifold and it was auto transmission but the week before I was at another dealer and they had a manual transmission and it had a red painted manifold, does the manual have red and the auto not?

That's correct, the automatic has no changes to engine so there's no red manifold only manual cars have those.

Exactly this.
The automatic is the same engine as previous years, so the red intake manifold is only on the manuals.

I remember reading that they couldn't get the Auto to pass certain noise level requirements when downshifting, so they had to keep the same engine as last year. (Or something to that effect, if I recall correctly)

The color red in the manifold provides that 5hp gain. ��

Thats your punishment for buying an automatic :paddle:

That doesn't make sense. Whether the the car is a manual or an AT being driven in manual, they will make the same noise level.

There's something up with the 2017 Auto...They're giving "more power" and a different rear end to the manual. My guess is they're just trying to appeal to a different market with the AT.

Manual gets a RED one AT gets a black one...:)

The have two different engines and diffs adds production costs so I doubt it is a marketing ploy. "Hey you want AT? Well we kept the power and acceleration down to your level" won't sell many extra cars.
I have never heard of a noise requirement that would have such a fine line that an AT would fail and a MT pass. I am guessing that it is more likely a mileage or emissions requirement issue that would cost more to correct with the AT then it costs to have two engines in the system.

I agree with you. Are there really two different engines? Or, is it the 4.3 rear end causing an issue with emissions/mileage in the AT? Purely guessing here but none of this makes sense.

There are two engines. Even the car configuration sections of each Twin shows the AT with the old engine specs.

Okay, but why? 5 extra HP can't go into an AT? Old engines laying about? Unlikely.

Kinda funny when you think about it and not believable.

If I was privy to all Toyota/Subaru's business plans I would be worth millions. We may never really know but I am sure that there is a legit reason for it since neither company is a Mom and Pop operation making random or unwarranted decisions. It really isn't something open for debate or to be disbelieved by anybody.

"... Buyers who order an automatic transmission will have to make do with the previous 200-hp engine and 4.10:1 final drive; engineers tell us the automatic cars could not clear pass-by noise regulations during downshifts with the new engine..."

Just stating what I read. :)

My thought is that Toyota/Subaru have too many old parts left in their bin so they would like to empty the stock. My guess is that the red manifold together with other engine upgrades will come with the A/T in the future, like 2018 till the end of production of current BRZ/GT86.

Most likely the MY2017 engine block is the same, the manifolds are different.

The old engine and new engine had same overall specs, and nothing different about the combustion chamber shape or burn characteristics. The manifold changes would've necessitated a change in ECU timing and fuel maps, hence the "AT with old engine peripherals and MT with new peripherals" as something that points to emission-related engineering requirements.

If you want that red intake manifold, you can buy it and install it on your AT car. iirc you can swap em out.

Has someone figured out what the small unfinished 'tabs' are for on the manifold?
Maybe an engine cover that's coming out next year?

..I've already had one person asked me whats suppose to be there

I've already answered this, its for the top mount intercooler for the BRZ STI, duh. ;)

Those tabs look to be in the same position as the tabs on the previous gen intake manifold.

The new manifold is probably shared with other Subarus to increase the commonality of parts as they adopt the FA20 engine as well. I wouldn't be surprised if that's where the intercooler bolts onto on a WRX or a Forester.

I'm gonna swap out my intake manifold for a red one once I can get my hands on one :D

Aren't those the tabs where the plastic cover attaches too?

This might be a worth while upgrade, as I read somewhere that the red intake manifold is slightly bigger than the old plastic one.

Dyno proof?

Proof of what?

You couldn't prove that the red intake is responsible for anything as there have been too many other changes to the motor. That 5-15 whp could be coming from many different things. Lets just enjoy the fact that metal is better than plastic :)

Things made of metal are generally perceived to be of better quality.

Cause I think it looks better.

Judging from your previous posts, I'll be waiting for a snarky response.

So more weight for nothing?

I honestly think you just prefer the one that you own over the one that you don't own.. but I don't know you.

Possibly, maybe not. You should buy one and let us know.

Then i will need to retune. Im more interested with the headlights

It would be nice if someone bolted a revised manifold to an older 86 to see if it provides any improvement in power.


The car is still too new though. Give it a month or two.

red is usually fast ...like woman that wear red lipstick so it must be better

Sounds like an expensive mod for no performance improvement. I do understand buying a Velox or something, but red lipstick on a manifold wont get my money.

I wonder what ITBs look like on a boxer.

Not bad

But red lipstick on boxer shorts is priceless.

The entire intake system has been redesigned, including the manifold to include better airflow going from a oval cross sectional area to a circular design that makes for a more efficient system. Its not just pretty red paint.

And oh.. the air filter, the valves, cam shaft, piston heads, engine block, fuel pump, exhaust manifold have all seen revisions

I know. I read the brochure too.

I saw a youtube video of the yellow series...the engineer said that they advertise 5hp, but its more like 15hp increase to put the engine where it should have been in the first place.

Definitely not 15 according to Toyota's marketing material. You see more torque in the mid-range and at the top, but HP gains are marginal - possibly offset by added weight. Unless their reported figures are conservative. But until we get actual dyno results from an owner... The red manifold does about as much as cheetah blood or flame stickers :cheers:

Frankly, I'm kind of surprised they managed to only get about 5 hp and lb-ft torque out of it. I mean, a drop in filter alone usually adds around that and they improved not only the filter design but also the intake, exhaust, lowered friction, and optimized other things but yet.. minimal gains. You had one job Toyota/Subaru! :paddle:

Oh well... at least it's something.
