Nope. More like a clutch type in action. This is a generic pic. The Mazda diff has a separate stamped steel bowl shaped plate with radial grooves that sits over the cones and bears against the outer housing. The one in this pic has no plate so the cone bears directly onto the housing. Seems crude but apparently it works. Early feedback is that the OEM ND LSD has a fairly low locking ratio. This heard second hand from someone who would have direct experience with it. I haven't driven an ND yet.

I worked as a "product specialist" in Canada for Mazda during this year's autoshow season. The answer we were given to field "why no diesel in any Canadian models" was "because US customers won't buy it and Canadian certification runs on the back of US certification".

The 310hp 2.3 ecoboost in the Mustang is in the same family of engines as the MZR and may one day be a viable swap candidate for the NC EDIT: but not the ND.

large turbo runs ALL OF IT levels of boost.

The Skayctiv 2.0L is not based on the MZR. It has more in common with a 4B11 Mistubishi motor than an an MZR once you get inside.

<br /><br />I'm gonna take this as a product announcement <img src="images/smilies/smile.gif" border="0" alt="" title="" smilieid="1" class="inlineimg" /><br />
<br /><br />When can I buy the 949 4B11 swap kit. That could be fun.

The diesel engine’s boosting setup, comprising a pair of Garrett turbochargers and a sophisticated air-to-air intercooler array, is based on the production Sky-D. It’s the first motorsports use of a compounded turbo system, Tremblay claimed. A large low-pressure turbocharger draws in and compresses ambient air, feeding it into a smaller high-pressure turbo which compresses the air again and forces it into the intake manifold.
Compared with a single turbocharger, the compounded-turbo arrangement provides a greater range of operating efficiency, [SpeedSource President Sylvain] Tremblay said. However, it is more complex and difficult to package in the car. The arrangement is not to be confused with turbo-compounding used on some reciprocating aircraft engines and the Detroit Diesel DD15 heavy-truck diesel, where one of the turbines is connected mechanically to the engine’s crankshaft.
“And it’s not sequential like on some gasoline turbocharged engines,” Tremblay explained. “One turbo charges the other and they’re not regulated mechanically in any other way other than by the actual computer control mapping of the turbos. As one compressor stalls, the other picks up that particular boost. It’s a very effective system for the Mazda race diesel.”
Maximum boost pressure used during the race will be in the 50-55-psi (345-379 kPa) range.
