Bye bye turbo #2!!!

lol mazda is cheap for giving us an award winning, Wards top 10 motor?

There doesn`t appear to be huge amounts of "room" left for this engine to grow without needing its innards beefed up. Compared to some other companies that have reps for building engines capable of being modded like mad before you need to crack the engine open. In that respect, yes, Mazda cheaped out on us.

Which goes for all the mazdaspeed models, the car looks great, runs great, but quality engine parts ehhh not so great.
 
I've spoken with my mazda dealer about the thicker oil and they told me that doesnt fix anything, its the PCV system thats causing the issues and mazda is trying to fix it currently. 5w-40 couldnt hurt but its not going to fix the smoking issue long term.
 
Hey just wondering what type of power k04 can take. I mean 19 psi just might be to much. Just asking

wait, so your pointing the finger at the motor company for you wanting to beef up a motor they didn't design for that purpose? The motor was designed to be efficient and one of the first of its kinda with new technology, not something for the weekend warrior to decide he wants to get the most HP he can out of the stock setup...... its suppose to be good on mileage, have some ass, but be economical all in one package, i think they did the job they set forth to achieve, wither you get your 350whp or not. if you want something that was ment to be crazy HP on a more stock setup, buy an Evo or a Cobra
 
I think 18 psi is about max for a stock K04, 19 is a little high and I think the turbo would just start blowing hot air after that.
 
18 psi is the surge line on the stock K04 turbo map, is it not?

You can't electronically change the turbo's internal efficiency characteristics with a tune. You just make a little more power and a LOT more heat and end up toasting the turbo.

Regularly boost above the surge line and a blown turbo is not unexpected, IMHO.

Maybe Ken's reworked PG K04 might give a little more room on its map to run 19 psi safely?
 
No offense but the **** the reworked k04. Theres been a couple tuned at surgeline with the reworked stockers and they only put down about ten more whp. Not worth 800 bucks imho. From the info i've gathered our engines if tuned right can run around 400whp and lucky for me i live near the only person actually able to tune these from what i can think of. Feel free to correct me if i'm wrong on the tunin thing
 
mazda made our turbo small intentionally for their own reasons i wish they hadnt. most engines, even other makes need proper dyno tuning. not sit at home and try to figure it ot on youre computer with a flasher, when you start modifying adding bigger turbos etc. the stock tunes are thrown out of whack and even high end internals will break at some point. even 400-500 horsepower evos dont just get there by just slapping a bunch of parts on adding fuel and driving away. most ive seen or come into contact with are dyno tuned at a real shop by people who make a living tuning.

You should know to not look at peak horsepower only. The reworked turbo spools a little later but holds the power almost to redline, where as the stock turbo will fall flat at 5500, which we all know. How much do your tuners charge an hour?

When you are selling a car that is targeted at people like us, you should build the car the way that people like us need it to be. Granted, the economics of scale for a limited edition vehicle mean that it would cost to build the engine stronger from the factory, but this engine is used worldwide in multiple models, so it wouldn`t be that bad. I think every one of us would have had no problems paying two or three hundred more out the door to get a motor with a bulletproof bottom end that is ready to be seriously modded once the warranty runs out.
 
Try a catch can.. see what happens after a few days.. Otherwise if you don't have the money or the desire to build the internals.. you could look into the reworked k04 from protege garage i got it and it makes a noticeable amount more power than the stock turbo and runs a lot more efficiently and safely with higher power numbers like we have.
Its just another option before going gt series

+1 on this suggestion

Your situation is: DD car with stock bottom end and you have limited funds? Go reworked K04 AND a catch can setup.

I don't think I understand your post. Are you saying that if your turbo is toast and have to replace it anyway, that you shouldn't get a reworked K04 rather than putting a pure stocker one back on? That does not make a lot of sense to me. Maybe I musunderstand?

As to the tune, are you saying that a fully bolted MS3 engine with a stock K04 or a reworked K04 can be tuned to 400 whp and not pop? I'd really be skeptical of that.

And why such a fanboy for Surgeline? I understand they do good work, but damn, they are not the next Messiah of MS3 mods. I though we were just talking about running one more pound (19) of boost safely? Aren't they the guys that did your tune and set you up to run 19 psi on the stock k04 in the first place? With a name like Surgeline, I would have thought they were aware that the K04's efficiency map has a surgeline of 18 psi. and pushing it beyond that is likely to make it a good boat anchor. Maybe I'm not understanding something here. We're just trying to understand and trying to help.

a little bit off here....

The reworked K04 wasn't to make more power in itself. It was made to allow the possibility of more power than the stock.
 
oooh nooo... i mod the F*** out of my car.. why is my turbo going bad? I'm only running more PSI and more horse power than what it's designed for.

Come on people, you heavily mod your car what do you expect? No sympathy for you man. I hope you DON"T get it covered under warranty as you shouldn't. you have to pay to play. And this is geared just to you just everyone else who also complains about the car when they are adding power to it that it wasn't designed for.

end rant.

the car is targeted towards us, the motor in the other hand is used in multiple vehicles, ones that having a forged, "bulletproof" block isnt going to be cost effective for. you have a forged crank, i think you can take it from there

not true im spiking 22 and holding 20 all day and trust me it isnt hot air, lol my freind has a speed6 and he pulled his wastegate line for fun one day, the car was boostin like crazzzy, it was a ****** animal, spinnnin all 4 in 2nd, but that was for like a half hour then he pluged the line in again, just cause by the end of the day the whole car would of exploded lol
