You'd have to look close to tell it apart from an OEM cast duratec crank to be honest. It's out of a 2009+ MX-5, after 09 they were fitted with a forged crank as standard. The counterweights are shaped slightly differently and obviously there's no casting line, but other than that they look very similar. I had this one sent over from America, as even with shipping and duty, it was around £1000 cheaper than from Mazda UK.

The MZR 2.0 gets all the good stuff compared to our duratec, VVT and forged internals being the major differences.
