VERY interesting data! but is it correct??!

where did you get the data from?

looks wrong - my 325i engine being 5 Kg lighter than the latest (M52) 6 cylinder engine with aluminum block!

Remember the M20 is a 12 valve single cam belt driven engine. The M52 aluminum block still has 24 valves and a chain driven DOHC head. I agree with the data, the M20 should still be lighter and it is. If you look at the M50, it's evident that the aluminum block saves plenty of weight already just not enough to make it lighter than the M20.
