Great color, btw!



Well, crap.

I was curious about the start up noise under the bonnet. Time to find a mechanic.

It looks like this Cox Performance unit is the VVT Actuator that should be used. Agreed, or other options?

Thatís kinda pricey. You can get a complete OEM parts VVT kit on Ebay for somewhere around $450-$500 or so.
From what Iíve read, you should expect to pay $1500ish if you have a shop do it. Donít know if that includes parts.
Watch your front pads and rotors, spark plugs too. Iíd go ahead and change them(plugs) if you have no idea when they were last changed.
Youíre going to enjoy your Speed, just make sure you take care of itís maintenance.

Thanks Bill.


Yes, the Cox Performance part is a bit expensive, but others recommended it.

The local Mazda dealer quoted me $1100 to $1500 yesterday, including parts. The higher number included timing chain and guides.

My preferred mechanic, who I've used for years on different vehicles, isn't quite as familiar with this so I sent him links to some videos and threads.

He's the guy who would also go the extra mile while in there and not rake me over the coals.

CarFax says plugs and coil(s) were done around 40K miles, along with the knock sensor twice. Something was going on with this car at 40K.
I don't know if the plugs have been done since then, so will have them done with this same service.

Also clean out the EGR tube as other threads have mentioned it being nearly plugged up while doing the VVT.

How about the water pump? Should it be replaced also while in there?

Definitely change the water pump, itís cheap insurance. Also change the thermostat, theyíre prone to leaking as they are made of a thermoplastic.

Be careful when messing with the Bose stereo. The head units are absolutely excellent, but the speakers amplifier are trash. Pure junk. And, because of the way Bose makes their stereos, the speakers and amp are made to match each other. If you replace one, you HAVE TO replace the other.

I highly recommend you keep the stock head unit, and tap into it using a PAC MAZ-AOEM adapter. Then get a half decent amp and speaker set like Rockford Fosgate or Mmats.

Good info, thanks.

Where can I read more about this and common solutions?

Right here on this Forum. Lots of people have been down this road, and it's well documented.
