This may sound really lazy to some of you, but believe me I don't have a clue where to look!

I am doing a piece of coursework for Uni which involves taking a product apart (in my case an RB Nitro Engine) list all the Sub Assemblies, Components etc and then find out what materials the parts are made from and why. I could do with knowing what the proper names of parts are too, instead of writing Engine Block cover etc...

Can anyone help?

Cheers!
