BTW...There are currently about 60 TSB for the CX-5 and 2014 Mazda 6, about 95% of them are all for the CX-5.

So again if you want them all uploaded here let me know?

We are not a 6 or CX-5 Forum, so I don't really know if there are even specific forums for these models yet?, I have not looked and frankly have no need or time to joint them.

Perhaps if you (SNTP) can get a consensus from other Skyactiv members here on the RX-8 club, then I will re-title TSB with a heading and post in a specific thread...

But, I am not doing so if it is not needed or necessary.

I would definitely like to have the TSB's.

There aren't many nuisances for my 2013 CX-5 (9/2012 build) other than the rattles at ~3000 miles. I still haven't brought it to the dealership for service yet as I want to look into the rattling problems closer so I don't get turned down for service.

There only seems to be three active members with SkyActiv cars on here, including me of course. I'll post in the two Mazda6 owner threads on here soon.

I vote yes, and I'm not a member of the SkyActiv club (yet), but your TSB does in fact include the VIN range of the CX-5 I'm waiting to arrive.

Speaking of CX-5's, and having your attention at the moment, Ash, can you tell me the part numbers of the CX-5's pistons both in the US market, and the non-US markets that have the higher compression ratios for the 2.5 liter engine? How much do they cost?

I'm tempted to either pick up an ornament for my garage, or a full set of higher compression pistons, for possible installation into my soon to be procured car.

BC.

PYY1-11-SA0 Piston all 2.5 SA Engines, about $102 USD

PEY1-11-SA0C Piston 2.0 SA in Mazda 3, All countries, about $76 USD

PEY2-11-SA0A Piston 2.0 SA in CX-5, All countries except Europe/UK, about $60 USD

PEY3-11-SA0A Piston 2.0 SA in CX-5 and Mazda 6, Europe/UK (not available in USA or Aust)

So the SkyActiv 2.5 is the same compression ratio in all countries?
I thought it was lower in the US, like on the 2.0 engine...

Or do they change the shape/size of the cylinder head to lower the compression ratio?

BC.

I have a 2014 Mazda6. It would be great if you could post them in a new thread!

Thanks in advance!

Hi, ASH i've also ordered a 2.5 AT wagon...TSB would be good for me...it seems that 2.5 have common specs for all the world....and here is EU is very difficult to get info for the low % of sales of this type of engine....

Well the good old BS in Mazda (Car) marketing continues...:)

It appears all the so called different compression ratio's are BS for 2014 Mazda 6, or ' ECU tuned' (I would like to know how).

As ALL ,repeat ALL 2.0 Litre Skyactiv Engines in Mazda 3, CX-5 and 2014 Mazda 6 2.0 use the exact same Cylinder Heads, Valves and Camshafts....NO Difference, for ALL Countries.
PE01-12-111 Inlet Valves
PE01-12-121 Exhaust
PE01-10-100 Head
PE01-12-420 Camshaft
PE01-12-440 Camshaft

Same for 2.5 Litre used in Mazda 6 and CX-5
PY01-12-111 Inlet Valves
PY01-12-121 Exhaust
PY01-10-100 Head
PY01-12-420 Camshaft
PY01-12-440 Camshaft

So there you go..

That is why I love EPC's, provided you know what you are doing, it cuts through all the BS and Marketing BS, if the Part Number is the same then....the part is the same.

Like the 2013 NC MX-5, with so called improved Brake Booster and Engine Tune, according to Mazda's marketing spin, well guess what the part numbers are identical to the 2012, 2011, 2010 and 2009, so again more BS...in fact there are NO mechanical changes to 2013 Miata, only a front face-lift....OH Europe/UK get the pop up/blow up Bonnet/Hood.

What about the part numbers for the camshaft phasers?
You know, those parts that are connected to the timing chain, and actually modulate the intake and exhaust profiles according to ECU inputs?

Are those the same or different?

Sorry, that's the last real part I can think of that changes camshaft profile outside of ECU programming.

But is sounds like we would love it if you made a thread/forum just for SkyActiv updates.

BC.

You mean the VVT Actuators connected to the Camshafts (Inlet and Exhaust)..

All the same for all Skyactiv Engines 2.0 and 2.5, as are Hydraulic Lash Ajusters and Rockers Arms.

PE01-12-4X0B Inlet VVT (Electric)
PE01-12-4Y0B Exhaust VVT

P301-12-100 Lash Adjuster (16)
PE01-12-130 Rocker Arms (16)

ASH, european Mazda official press release (in its tech specs part) say that stabilizers of 2.5 are 1mm bigger than other models.

is it true? (remember..euro-spec)

look @ "stabilizzatori" (italian word for stabilizers)

Just lost a detailed reply???...not going to do it again.

But yes, 2.5 and 2.2 D Mazda 6 uses larger Front Bar GHT6-34-151

2.0 Mazda 6 uses 2.5 CX-5 Front Bar KD61-34-151

2.0 CX-5 uses a smaller again Front Bar KD35-34-151

So an upgrade for CX-5 owners can use 2.5 Mazda 6 Front Sway Bar.

Drop Links are all the same for all and from original CX-5 KD35-34-170 (2).

Like the RX-8 and NC Miata/MX-5, these 2 new Mazda's (CX-5 and 6) use the same shared architecture design.

Thanks for the info and discovery. I assume the sway bar mounts and bushings are different as well? Anything on the rear sway bars being swappable?

Now that's awesome.
I'm adding that nugget to my parts list collection.

How about the rear differentials?
Would it be possible to put the torsen limited slip parts from an RX-8/MX-5 into the CX-5?
I know there would be the ring and pinion changes, but having limited slip in the rear of the CX-5 would only add to its winter/mud/off-road abilities.

Let us know if we start driving you crazy with questions...
I'm just a little excited, that's all.

BC.

I'd imagine DSC to kick in before the LSD can even be of use. I was playing around in snow today with TSC off (can't disable DSC), and DSC would kick in at any given opportunity. E-brake locks the rear wheels only even when moving as the AWD system releases the multi-clutch in the rear diff upon engagement of the e-brake. Optional FWD :rofl: .

yes to bushings.

No variety for Rear Sways, except they are different or each model, I assume the rear
6 will fit on a CX-5 but cant confirm, CX-5 has one for 2WD and one for 4WD.

An interesting observation is the REAR Bars on the CX-5 and 6 looks similar in design to the Fronts on RX-8 and Miata, and the REAR Bars on the RX-8 and Miata looks similar to the Fronts on CX-5 and 6.

Hey Ash. Would you be able to find the part number/s for the 2013 and 2014 headunits with the screen?

Be more precise, what exactly are you talking about :)

Apologies :lol: ... The headunit with the 5.8" LCD screen that leaves the option open for add-on's such as the U.S. "Tech Pack". I believe they are entirely different parts due to the software change and the additional chrome accents in between the buttons for the 2014. Just wondering the part numbers for 2013 and 2014 for said headunit.

You need to PM me your Full VIN to give me a baseline as there are multiple models/specs, sorry but it helps to speed up the process instead of me spending 30 minutes on your request....

So you get the right information from me and YES I understand your question.

Did some prelim checks, you know these units to buy are between $1300 and $1900 USD depending on specs and transmission and sound system and VIN..

The ONLY parts you can buy separately are the two Knobs KD45-66-BC1 @ $8 each, everything else is ONLY available as a complete assembly @ the prices I have shown, certainly nothing below $1300 for OEM unit.

As I said , depends on VIN and car specs.

The difference between the current Mazda 3 2.0L skyactiv & CX-5 2.0L skyactiv are piston cavity & the 4-2-1 exhaust which allows the raised compression from 12:1 to 13:1. These numbers are also lower than international models 14:1 due to use of lower octane fuels.

You will see a compression ratio of 13:1 in the new Mazda 3 2.0L & 2.5L Skyactiv engines. Piston design will be slightly different and the new exhaust design (4-2-1) will be incorporated.
