Some are new.
N42 was available in e46 - not much of a performer, was primarily for economy producing around 115bhp. Its an I4.
What you're referring to is the N54 from the 335.
I actually have no idea if I will get any of them, I guess we'll find out! (isn't that the point of this post!)
I know a guy on here is selling his M40, but don't know what condition it's in and hasnt gotten back to me on the queries.
I would like to think more people would be doing JZ conversions to their e36s since their pretty reasonably priced now. I know if I wasn't tied up with my e21 project thats what i'd be doing!
Anyhow lets see...
