08 Focus Forged Crank?

Does anyone know if the 08 Focus has a forged crankshaft?

I know FSWerks have built plenty of cars with the stock crank and havent had any problems.

I heard the earlier versions were not forged but the later cars had a forged crank not sure which years or if its true or not, just trying to clarify if it is or not if anyone knows.

Wow, forged cranks, but not forged pistons= na, can't be. I'll take forged pistons w/ a cast crank.

This is the setup most people do.

I believe you will break many other things before the crank would go. I'm not sure if I've seen any Duratec cranks break but I could be wrong.

Yea I havent beenable to find the info again either, Im kinda thinking that maybe the Ford MZR's are all cast and the Mazda MZR's are were the forged were changed but IDK for sure.

Im not concerned about it breaking but from what Ive read theres about a 5lbs difference in the 2 and I feel having less rotational mass would be beneficial. That and if your going to do an engine build why not go all the way, I mean really whats another $325 or so on an engine build? That an if no one ever does it then theres no way to prove what the benefit of having 1 would be. Maybe I just prefer to try it cause its different and I don't want to have the exact same thing as everyone else.

Thanks for confirming that. Would you happen to know if all Ford MZR cranks are cast? An do you know what the weight differences would be for cast and forged for both 2.0 and 2.3 cranks? It would be nice to know even if it doesn't make much of a difference.

The Cossie forged cranks are lighter then the stock cranks, & they'll really lighten your wallet too. I'd just start out w/ a ranger crank. Its not like your running formala alantic motor. I'd spent the money on rods/pistons & valve's.

Your still thinking 2.3 only although cossie does make 1 for the 2.0 but yes the cossie is pricey and may not be worth the money and the 5lbs difference I mentioned is in the ranger crank and standard d23 crank so yes using the ranger crank for a d23 built would be better then spending 3k on 1 part, enless your going all out, however d20 owners have the option for a forged crank for about $325, it can be found here, at least it says it forged (IDK)

But if it is then I feel it would be more suited for a daily driven, high boost/rpm car and would still give you less rotational mass.

Yeah, Thats what I'd do for a 20 motor, but there's more to be had w/ using a 23 to begin w/ & add a ranger crank. Why don't they do a 23 crank, at similar price?

The crank from a 2009+ MX5 Miata will fit and is factory forged. Confirmed that through GP-Werks last year. It is a little heavier though.
