I can't tell you right now as I am in the middle of moving house and the parts manuals are in a box somewhere! (I just had a quick look through the hard drive too, but I just don't have time - sorry!)

MC16E is the "generic" model type for the NSR motor - a bit like "Series 3/5/7" for BMW cars... they are all "Series X" but they all look different!!! :)
