    M20 vs M50 vs M52

    Hey guys, I wanted to hear some of your thoughts on whats better, the m20, m50, or m52 and why. Personally I have fell in love with my M50, but had to give mad props to my M20 before it threw a rod. What do you guys think?

          I think Jacob needs to get his M30 running before he can vote for it.

            You need to proof your panel! Personally, M20 because it is a classic design and there are plenty of room in the engine bay.

                    Blue flame six..

                    Oh wait, what was the question again?

                    Honestly, they all have their pluses and minuses. I favor the M20 only because I have a bunch of spares and parts lying around and they are stock in the E30, so no need to custom fab stuff to swap them in.

                    In my book, any motor from any manufacture has some cool features, and some weak points. But then again, I am just a car guy who likes to tinker...

                    ..except air cooled VW. I don't understand them and as far as I am concerned they work off Pixie magic and Unicorn blood.

                        Honestly, for my daily driving needs, my M20B27 is a great engine. It's now just over 450K km and it's still running strong. Yeah, it's got a timing belt, but once you've done it, it's a pretty easy job, just a bit time consuming.

                          N52 - the torque of an M30, the weight of an M42. :p

                            you cant vote N52 until there is one running in an e30 or maybe there is already?
