do you drive your car hard? when you slam on the accelerator you're providing a sudden surge of power throughout the engine....... I guess sometimes, it's just too much for the internals of the engine and the connecting rods being as flimsy and crappy as they are snap.
BTW just to let you know...... running the gt3071 "at stock PSI" does not mean you're at stock PSI, the gt3071 is a bigger turbo and flows more volume of air than the stock k04 turbo
so when your stock turbo is 15 psi, we'll say for example you're flowing 650 cfm of air, ok? now when you have the gt3071 at 15 psi, being that it's bigger and allows more airflow....... you would actually be flowing (just an example) 920 cfm.
You understand what I mean? Even though you have the GT3071 at the factory PSI boost setting, you're still making more power than the stock turbo on your engine.
And people have been blowing engines with just the stock turbo on the engine. So maybe you don't drive it so hard?
I was driving the car hard, and 18psi and 20psi spikings are adictive, the faces of STI's and Evo owners were incredible.
But then I read the drivetrains are coming apart, rear diff are trouble and all this engines started to blow. (man this is the car I bought to be different, and not be another STI or EVO owner)
I can't afford a new engine, right now.
So I ordered ATP a 7PSI wastegate and I am running stock 14.5psi, (7psi wastegate combined with factory boost controller).
I know 14 to 15 PSI of a GT3071R is more air flow than the K04, but is a lot less than 18-20 PSI.
NOW I am driving very carefull, not trying to break anything.
Any way more info. is needed, why these motors are blowing, will MAZDA do something about it?
Is this a 2006 problem or also 2007 models are blowing?
