rich280zxt Posted March 25, 2008 Share Posted March 25, 2008 Cb Performance has these velocity stacks http://www.cbperformance.com/catalog.asp?ProductID=512 I wonder if they will fit Weber 40 DCOE carbs with a little modification? Anyone know.. Quote Link to comment Share on other sites More sharing options...
madmatt48 Posted March 25, 2008 Share Posted March 25, 2008 They should fit as they are. Weber, solex, mikuni side draft dcoe carbs fit velocity stacks the same bolt pattern. Quote Link to comment Share on other sites More sharing options...
rich280zxt Posted March 25, 2008 Author Share Posted March 25, 2008 They should fit as they are. Weber, solex, mikuni side draft dcoe carbs fit velocity stacks the same bolt pattern. They are IDF's though, isn't there a difference? Quote Link to comment Share on other sites More sharing options...
madmatt48 Posted March 26, 2008 Share Posted March 26, 2008 by the picture in your posted link, the bolt pattern looks identical. Only by way of measuring the bolt hole spacing and comparing it with the 40 dcoe flange could you be 100% sure. I have exhanged velocity stacks several times between weber and solex/mikuni side draft carbs on a 1970 240z, 1979 280zx and 1981 Nissan Laurel I had owned in the past with no issues.

Collectindust240Z Posted March 27, 2008 Share Posted March 27, 2008 I don't think Dellorto stacks will fit Webers. Don't the Weber stacks sort of insert into the venturi? Quote Link to comment Share on other sites More sharing options...
rich280zxt Posted March 27, 2008 Author Share Posted March 27, 2008 yea they do, but I don't think its neccessary, as long as the holes match up, they should be fine, which is my question, I'll send them an email asking for a measurement.

RedNeckZ Posted March 27, 2008 Share Posted March 27, 2008 I have 45mm DCOE's and a Electromotive custom air cleaner. You can go with both the slip in and bolt on stacks. I have bolt on stacks with the custom air cleaner now. But have the insert stacks in the garage to be used with the three individual air cleaners. Good Luck, Rich.
