crankshaft pulley
 

Are there any alternatives for the crankshaft pulley? CS doesn't make them anymore.
Looking for a set including waterpump, alternator, etc but would like same size only lighter. Maybe one of you has experience with pullies from other cars fitted on a Mazdaspeed? Maybe sizes of the different pullies?
Building up a forged engine

what are you looking to achieve by this ? Do you already have a lightweight flywheel ? it is probably where you can gain the most and the more easily....

You may check if ford pulley are similar since the engine bloc is from the same family but imo it doesn't worth it. it isn't a high revving and peaky engine but a torque monster. I would save that money to use it somewhere else....

The pulley on the build engine has some bites out of it. Most of the time such a set is cheaper. I have to replace it anyway, so why not do it lightweight. Oem is more expensive i believe. It's not for the gain of 6 HP. Just need good replacement or other alternative that is cheaper than oem.

you can probably import a used oem one from middle of USA, there is many blown engine with no use of this part...

Or you may ask speedshop about focus parts. If you look at thins one it is very similar but the tooth wheel doesn't seem attached....is it just not pictured or the focus has it bolted and you re-use it???
