No one makes this car anymore. The government won't allow them, normal people won't buy them. So it's up to us: the freaks, the weirdos, the informed. To buy them, to appreciate them, and most importantly, to drive them.

But lately I've been thinking that it would be nice to have a few more cylinders. It could just be because I haven't driven my car in a while and I forgot how fun M42's can be.
Plus I've got a 325i convertible with 160,000 km's that I may be parting soon, so I'm tempted to swap in the M20.

Small updates:
The aluminum tubing showed up a couple days ago, so next week I'll cut a couple pieces and get them tacked on to the manifold in order to check clearances. I also made up a set of stainless steel spacers to space one set of throttle bodies...
I'm still considering what approach to use to extending the throttle sync tabs. Right now I'm thinking that since it's only 8mm they have to be extended I will just build them up with weld and then just grind them back down to the proper thickness. If that doesn't work I'll have to cut off the current tabs and fashion a small piece out of flat bar that can be welded on...

This is very interesting.
Giving good thoughts for my own itb project..
Do you include intake port to your plans? You are now doing just another "curve" to different position. Notice that intake channel has already 2 curves as it should be one tightening curve to accelerate air flow
Here how it should be done.
And my own drawing
