4.0 L speed 6 engine materials

[Barile91]

Hi,
i'm an automotive engineering student and i need to find the materials of the connecting rod , piston pin, piston , crankshaft of the original MCD 6speed 4.0L engine . The shaft material should be EN 40B.What about the other components?
thanks to all

I have to improve an existing engine. I chose this because I found some dimensioned drawing in the network. please reply if you can be help me. thanks

For all intents and purposes the MCD speed six doesn't exist....

sorry, i meant an existed engine.
it's just a project for us to learn how to make the structural analysis of the components. I do not have to produce a new engine.
...and i know that Lambo's v12 is probably better then speed6

Hi,
I am not sure about the crankshaft being EN40B. Maybe that´s with aftermarket shafts.
There is a SAE whitepaper from 2001 about TVR using ADI steel for the S6 crankshaft. It would have had some logic keeping that direction since ADI would provide a good compromise for low volume production engines (tech parameters vs. cost against forged steel).
Last year I had a 2001 engine opened and at least I can say that the crankshaft was not a machined EN40B type.
Good luck with your studies!

Thank you dirk. It's a EN40C cranckshaft. Now i'm sure
