Yeah, but I was still impressed by how much crap got in there. I have had the battery out before but it was in the middle of the night (when else do batteries ever fail) so I never even thought to look and make sure I wasn't carrying extra weight.

Also, while I now have a new appreciation for how Mazda managed to package this thing in here, with as many sharp 90* bends there are in the airflow and the way the turbo inlet pipe is dimpled, it's amazing this engine makes the power it does.

Do you have an aftermarket turbo inlet, or were you planning on installing one while you had everything disassembled? From your picture it looks like it would've been pretty easy to do, but I'm not familiar with how much power you would gain from that or if you have an AP.

No, I stuck with the stock inlet. Funny thing is, despite it being rectangular and heavily dimpled, apparently none of the aftermarket ones can actually show any significant, repeatable gain in power. All of them quote some nebulous 3-5hp which, in reality, falls pretty much into margin of error territory. A lot of people do say it spools better, though.

Aside from the Mazdaspeed CAI that was on it when I bought it, I plan on leaving this car stock for quite some time still.

Yes, I remember taking a peak at it when I was cleaning out my EGR valve (same code). It is a cute little thing. You said that you are still using the stock TIP. That thing is a total piece of garbage, and I cannot wait to get rid of my stocker. How was removing that little hose on the pressure nipple on top? Most everybody breaks it right off while removing it. As far as power gains go, I have heard about the same, negligible power increase but faster spools and more sound. I plan on replacing the stock intake and TIP at the same time, probably spring.

Stock boost should peak around ~15.6 psi, I believe. Someone might need to back me up on this.

I remember reading this in the owners manual. I have heard that the stock turbo can handle "short bursts" of up to 28 psi. Why anyone would do that I am not sure. (aside from the obvious POOOWWWWWAAAAAAA)

Removing the nipple on top was actually almost completely painless for me, I had no idea everyone breaks it until after I finished the job and decided to start researching TIPs.

On a completely unrelated note, the Mazda curse can strike anywhere, any way - even from behind!

All good alternatives to the Blizzaks. I've had experience with all three and have been satisfied. The Arctics are great in deep-ish snow, but give up some dry traction because of the large tread.

The 2010+ MS3's use 18" wheels too, not sure about the older ones but I thought they did too?

Does the MS3 have the massive brakes the MS6 does? There were practically no cheap wheels available under 18 inches that could clear the rotors so I've sourced a set of stockers.

The 2010+ speed3 has 12.6" rotors in front and 11" in back. From what I'm seeing it looks like (at least the fronts) that they are the same rotors on the Speed6. I'm running 16" steelies on my speed3, but they barely clear the rotors.

edit:
When I say barely, I mean it, there is only a couple mm of clearance between the wheels and calipers on the front.

According to tirerack, 16's won't fit the MS6 and they don't have any steelies in 17 inches. No biggie, I got my second set of OEMs for $400. Looks like I'm gonna drop $600+ on tires next weekend.

"Wikipedia: Mazdaspeed3 Article posted:

Volvo-sourced 12.6 in (320 mm) front and 11.0 in (280 mm) rear brake discs hide under 18 in (457 mm) wheels.

"Some Website I found on Google: Mazdaspeed6 Article posted:

Braking is by discs all around, with fronts measuring 12.6 inches and vented, and rears measuring 12.3 inches and solid. The brakes work in synergy with the four-wheel anti-lock braking system (ABS), Dynamic Stability Control (DSC) and Active Torque Split All-Wheel-Drive system to exhibit an outstanding level of active safety.

I keep hearing people talk about the Speed6 having massive brakes, but from the sounds of it, both cars share the same size front rotors. Perhaps the calipers on the MS6 are larger, but if not I would imagine both cars can run the same wheels (not considering offset).

In this case, you could run FD RX7 16" wheels if you really wanted to. I'm gonna go ahead and call shenanigans until someone corrects me.

Yea all the posts I'm seeing from MS6 owners say that 16" steelies don't fit on the MS6 for some reason. The rotors on the MS6 are the same size in the front as the MS3, the back rotors are slightly bigger than the MS3 because of the AWD. So that must mean that the front calipers are larger I guess?

I've got 17" Snowflakes from the Gen1 3 on my 2010 Speed3. 205/50-17. Factory is 225/40-18, by the way.

As far as the MS3 goes, I think the rule is that MOST 17" wheels will fit and SOME 16" wheels will fit. It depends on the offset and the wheel design.

So apparently Mazda has a new trim level called "GS-L"..... GS is a mid-level car (GX is low end, GT is high end). The "L" means luxury..... so you do not have to buy a top level GT to get leather. So how about a Skyactiv, 6 speed manual with leather for example.

Edit: Or should I say, they brought back the GS-L

Welp, I did indeed have a boost leak. Did a datalogging run and found I could only spike to about 12 PSI, with constant boost in the 8-10 PSI range even in third and fourth gears.

Came back, poked around, couldn't find anything. Came back to it ten minutes later and poked around still more and finally bumped against the clamp on the throttle body itself, only to realize it was completely loose :downs:

Tightened it up and voila, 15 PSI with at least one spike to 17 as reported by OBDII!

On another note: I haven't done much datalogging but OBDII was only reporting about 88% throttle, even in third/fourth with the pedal pegged. Normal, or something I need to do about my replacement throttle body?

SynMoo

Did you do a TB replacement procedure? I know on VW's they need to be run through a re-learn procedure.

That said, it's completely possible that the TB opens that far and modulating the pedal actually modulates the boost or a combination thereof.

In war, you kill people in order to change their minds. Remember that; it's fuckin' important.

I just picked up a 2012 w/tech on Monday to replace my poor old Accord that finally died. I'm having quite a bit of fun with it so far, and it is literally twice the horsepower and torque of the Honda. Clearly my next car needs 520hp and 560lb-ft of torque to continue the trend.

Can I just remind you all why I mostly avoid Mazdaspeedforums? Take a walk with me, won't you?

Summary: This guy, 'Corypechon' mods his car and then doesn't do any tuning. Not long after he blows the engine. He then takes the car to the Mazda dealership, mods still on, and expects to get a brand new engine. You get the picture:

Some lovely Mazda forum posted:

corypechon posted:

I'm going to contact mazda this morning. This engine blew due to an obvious lack of judgement on the part of mazda's engineering team by recycling manufacturing techniques that may be sufficient for a non-turbo 2.3 liter 4 cylinder but not for a 263 hp turbo platform, a scene mazda is new to and has very little experience in prior to 2007 (at these boost levels). They had a choice to use high quality materials when assembling internals and they failed us. I will hold Mazda accountable and they will put a new engine in this car at no cost to me. I'm going ape poo poo here. This is not my fault, I don't have to money to fix it, and I could lose my job because of this. Mazda has the resources to repair this and they will if its the last thing I do in this life, so help me god.

Our motors rock, your wanton modding with no planning and research was the reason this motor blew.

corypechon posted:

These failures are occurring in 6th gear at 60mph out of boost from bone stock to fully modified. 5000 to 90000 miles. They fail indiscriminately across the board. Its a bad engine in comparison to what I could have gotten had I not bought this car. Don't get me wrong I love the speed 3 and would like nothing more than to drive it till the wheels fall off. But Mazda designed a bad engine and those that haven't exploded yet are ticking time bombs. There was a point in time when this came to Mazda's attention where they needed so many of these they were back ordered from Japan for months and the faster option was to have them machined and rebuilt as opposed to going through re-manufacturing. The whole thing is borderline class action at this point.

I'm not sure what failures this guy is talking about. I've heard the Subaru guys claim that putting any load on the engine in sixth gear is bad and could end poorly. Accelerating from sixty in sixth is just on the edge of the power band, so I usually downshift a gear or two if I'm going to pass someone on the highway.

This is a pretty worthless post, but why do car forums gotta be full of such tools?

SynMoo

I accelerate in 6th gear from 60mph all the time. Power builds quickly and I'm at 80mph and past my target before I know it.

Is this really a concern with a factory tune? Surely I'm not in any danger of leaning out without a tune.

Power does build nicely, I've just heard claims that you should avoid pulls in the higher gears. The argument was something along the lines of building full boost at low RPMs because the engine is under a heavier load due to gearing, the AFR goes lean, and you get knock. This might be more of a concern on the STIs since their factory tune is garbage. I don't have any data logging equipment at this time, though so I have no idea what the KR looks like.

Edit: Downshifting to 4th and blowing past everyone is pretty fun, too.
