Ill tell them straight to there face.. SCREW UR WARRANTY i wanna know if the car can handle it
Over a thousand miles.
We're telling you right now.....the car can handle it.
NOS??? and thats a CHEAP and fast solution but peopel are right.. ur internals are gonna be shot... Im not sh itting on your 3 im glad you take pride in ur mazda but im curious to see how long it lasts.
I want to belive you man.. I jsut worry about my car. Its my kid and daddy doesnt know about any work i did to the car so if something goes wrong IM ******.
If your that worried about it.....don't mod it.....or check tht your dealer is cool with the mod you want to do first.
HAH! No Mazda dealership in my area is cool with mods. BUT I WANT THE POWER.. Im gonna wind up doing it sometime sooner or later... Ill just give it time and see how everyone elses holds up.

My turbo was replaced under warranty for smoking and the issue is now resolved. They performed a check on the PCV valve specifically to identify whether or not that was the issue. When the tests came back showing it was not, they replaced the turbo due to bad seals.
2 questions.
1) How long has it been since your turbo was replaced?
2) Did you smoke under acceleration before the swap?
HMMMMMM.. More doubt in my head now.. But even I smoke a little under acceleration
Turbo seals and overspool aside... a properly setup catch-can is a good thing on any modded turbo car. Hell, they're good on un-modded turbo cars too if you're driving them hard.
I'm not totally sure how the PCV system works on the MS3, but on the WRX/STi there are two circuits that benefit from catch cans: the crank/pcv breather, and the valve cover breathers. They both vent into the intake so if you're pushing oil out them, you end up sucking it through the cold side of the turbo to be burned in the engine, which screws with the octane of the intake charge, not to mention messes up the turbo if there's a lot of oil. I'm sure the Mazda is similar, no?

What kind of Turbo is in the Wrx/ STi?
Stock WRX turbo is a Mitsubishi TD04L-13T. Good for about 200-220 whp (which on an AWD Subaru is about 280-300 at the crank).
Stock STi turbo is an IHI VF39, starting in '07 I think they went to a VF43 which is the same as the VF39, but has a bigger wastegate to fight boost creep w/ downpipes. They're good to about 300 whp.
All three turbos are thrust-bearing, IIRC.
Aren't all Subarus AWD? What's 280-300 at the crank? WRX?? I don't understand your second sentence
And this is why it blows my mind that this K04 is having so many issues
If you tune a WRX on the stock turbo (CAI, up-pipe, TBE, reflashed ECU) you can make about 200 to 220 all-wheel horsepower, which works out to be an estimated 280 to 300 horsepower at the crank if you take the "standard" estimated 28% drivetrain loss.
I was just pointing out that the AWD system on the Subaru tends to take quite a bit out of the wheel power of the car... so saying "AWD Subaru" is a bit redundant, but not necessarily in the context of a Mazda board.
they.....aren't.....having.....that many problems.........
You've read a few horror stories on the net and most of those aren't even the turbo, they're the pcv.......

I made 245 whp and 249 wtq on my WRX with the little TD04 @ 18 psi. We never had smoking issues, catch cans or not even when pushing the turbo to its limits.
I'm still not convinced the K04 smoking is from the PCV system. If it was then why all the stories of Mazda replacing the turbos under warranty?

Here's a better question, why all the stories of people's cars still smoking after getting a turbo covered under warranty?
