M20B29 w/ Triple Webers into my '71 2002

^^ haha perfect, Cropping one for my little picture.

drutt23 - Thanks for the input, I've seen the type of setup you're talking about. I would need to run Weber IDF downdraft style carbs and then that would mean no the ability to use the manifold for ITB's.

Saw this IDF setup on an Alpina E21 M20 in Chile http://www.youtube.com/watch?v=78MrlRvrM9o - have to endure the bad music though.

This 02' is gonna be sick, stroked high comp with triple webbers is going make this car sing. I will be keeping an eye on this project hopefully I can learn more about the m20 into the 2002 conversion. Good luck with this build hope you go through as least obstacles possible.

Wow this was way cool until now.......now I'm not sure what to say because a triple weber stroker is way beyond cool....LOL! Nice work man! Keep it going! I'm sure I am one of many waiting in anticipation for these to be pounding concrete soon!!

EDIT: Almost forgot to mention my 2 cents for the manifold project....I feel that the manifolds would look much better with an up-swept look instead of sticking straight out of the head. The look of things would flow a bit better in my opinion. But the picture you have up might be throwing it off. I could be wrong. A different view of it might be better to really judge if my idea is reasonable or not.

Engine 1: My car (Ireland Engineering)


After finding out that the existing manifolds weren't quite what I was hoping for I'm going to attempt to make a new set of manifolds using my limited knowledge of Solid Works, Jeff & Jeremy's experience, and a measuring caliper.

Project briefing: M20 - DCOE type manifold

cast vs. CNC machined --- Cast parts have a higher up front cost dues to the cost of making a mold but residual sets will be much less than if machined. CNC machined has a lower up front cost but that cost stays the same for residual parts. RESULT: This 3 piece manifold will not be made in any great numbers to justify making a mold so CNC'ing is my best option.

Desirable attributes.
DCOE type flange to fit 40 DCOE with enough material to port to a 45 for a race applications. Most individual throttle bodies use the DCOE flange so including injector ports and vacum ports is a must. Those (like me) running carbs will want to run a top mount linkage setup so threaded holes for heim joints to hold the linkage rod are a must.

If anybody else has any input on what would should be included please let me know.

Excited as this is my first project of this magnitude.



Engine update:

Head back from machine shop. Ready for some porting, not that it needs much.


Took 1 rod end apart to find that the rod bearings were wore down to the copper. The crank has a lot of scoring and rather than turn it this will be a good excuse to go stroker!
