Hello,
Year/Make/Model: 2007 mazdaspeed 3
Mileage: Engine unknown body @ 248k km
Location: Québec
Concern: Wierd turbo noise
DTC's: (please include descriptions) n/a
Modifications 3inch custom exausht, COBB accessport on stage 0 and a COBB intake
ECU/Tuning Software: ACCESSPort cobb (1st gen)
Tuner: n/a
Is the concern intermittent? no
Can you duplicate the concern? Yes
Recent Repairs: Full suspension rebuild to OEM spring,shock and mcpherson, new doorman thermostat, refilled the AC, NGK ruthenium sparkplug at 0.027' ,
Correction:
I recently bought a 07' speed3 for a decent barging for what came with the car but now it started to have a weird whirl noise and i cannot figure out if its the turbo going out or the boost piping. The noise seems to come from mid firewall/upper left, also seems to be only doing it when warmed up. Also only does it when going above 5psi of boost, as long as i stay under that the sound dosent happen and the car dosent feel down on power. The guy i bought it from left me 3 turbo (2 pretty much brand new and 1 needing a rebuild) + the one in the car. I did read that the 07 had a bad batch of turbo installed so im wondering if i need to swap mine out for a good one. The engine is old but new to this car so i dont know all the history on it but i know the VTT and the timing component were done when he swapped the engine of the car. Im slowing building it back to OEM+ and so far i have rebuilt the brake and suspension. Engine tested good on compression (had to it semi cold, wasent up to full temps but had 168psi equal on all 4cyl) I know its a junkyard engine but it run very smooth and no oil consumption.
Ill attach some vid with the hope that you can hear the sound.
Please do not hesite to contact me or to let me know what i can improve!
(hope this is the right place for this question)
