Hi, Ken....Check out Mazdatrix.  On their home page, click on racing, then click on Weber IDA carbs, and you will see that they have both the 48mm and the 51mm. The 48mm costs $575.00, and the bored-out 51mm,  part number 16602, sells for $850.00.
      If I thought this would bolt right on to a manifold, and have provisions for leaning at altitude, my EFI would go back in the closet.  Did I say I like to keep it simple, no high pressure pumps, fuel sumps with fuel returns, MAP settings to deal with, etc?   I find it much easier to simply lean the mixture with altitude than to try to set up all this fancy EFI system.  Thanks for the info.  Paul Conner
