150 Posted May 31, 2014 Share Posted May 31, 2014 I recently bought a weber manifold for a 240z L24 but I'm not sure whether it was made for 40 or 45 dcoe. I measured the "C" value (in the attached photo) at 4.6 cm. Does that indicate it was made for a 45 dcoe? I dont have any carburetors to compare the diameters for the two and couldnt find anything online. On the producers website they have a kit listed for 40 and separately one for 45 so I am guessing they are somehow different Any help in finding out which carb fits the manifold is greatly appreciated!

Lazeum Posted May 31, 2014 Share Posted May 31, 2014 I believe you've answered your own question. I had to machine and port my manifold to match carb output on my Cannon Weber manifold to go with 40DCOE. Quote Link to comment Share on other sites More sharing options...
150 Posted May 31, 2014 Author Share Posted May 31, 2014 What I'm having trouble finding is whether there is a size difference between the 40 and 45 regarding the "C" value mentioned above. Is the hole of 4.6 cm that the manifold currently has too big for the 40 DCOE? Quote Link to comment Share on other sites More sharing options...
Leon Posted June 1, 2014 Share Posted June 1, 2014 What manifold is this? Do you have a photo? I'm just asking out of curiosity... Quote Link to comment Share on other sites More sharing options...
T-Bone028 Posted June 1, 2014 Share Posted June 1, 2014 To the OP, if it helps, I measured a spare intake to carb gasket, and it measured 40-41mm-ish. I recall when I installed my carbs, the gasket fit closely for both intake and carb diameters. So if your intake manifold measures 46mm (4.6cm), I would assume yes, it was meant for a 45 DCOE. Interestingly, I had always thought that there was not a 45 dcoe specific manifold for the L-series, and that it was expected that the owner would port match accordingly. Where did you get the manifold from? Quote Link to comment Share on other sites More sharing options...
150 Posted June 1, 2014 Author Share Posted June 1, 2014 Thanks for the information, I was hoping to install 40DCOE on my engine.. So this is bad news. The manifold is made by Mangoletsi, it appears to be a very well made part. The linkages are already installed and it has the option of wire or standard rod type throttle connection Quote Link to comment Share on other sites More sharing options...
Lazeum Posted June 1, 2014 Share Posted June 1, 2014 You should be fine using this manifold with 40DCOE even if it is not ideal. Here's a post where I've been asking similar question. You should take a look. Quote Link to comment Share on other sites More sharing options...
