In reply to this NO! I have seen,worked on and owend many cosworths, i have never seen a 4wd with a 205 block(unless the 200 block has been removed and sold on ebay), but i just dont rule things out as completley wrong and take the piss because i have never seen it.
so surely you can only say its not known of any in your opinions.(that you are of course welcome to have)
