The honda S2000 has forged and carburized connecting rods!!!!

Carburization is used to case harden steel parts. The process involves heating a part to some critical temperature and diffusing extra carbon into it. Generally, more carbon = harder steel. The result is a hard outer shell around 1/20" - 1/10" thick. The insides usually remain soft and unaffected. This is desirable because it creates a wear resistant part with a durable core. You will see this done to machine tools, gears, shafts, and all sorts of high wear items.


The "ancients" used to do this by packing charcoal and steel parts into some sort of clay jar and putting the whole mess into a hot fire for a day. Nowadays, you just give the local heat treatment shop $70 and they give the part back to you the next day =)


BTW, did they mention what alloy the con rods are made of?

Yeah the S2000 connecting rods are steel and the NSX are titanium....

Is very intresting to see all the different procedures that car manufacters use to make certain parts stronger....

The Corvette C5 steel connecting rods are made by the POWDER process.....Which one is better i don't know......

Its interesting because the fact they were carburized points to the usage of certain steels... most alloy and tool steels arent carburized and will harden as-is.

I was hoping someone would know what alloy they were made of. I tried digging through my S2000 service manual but couldnt find anything.

Anyway, this has gotten WAY off topic =)

I think that another great addition to the Next NSX would be a electronic damping system..That would enhance the handling of the car even more!!!!!!
