Twin sidedraught Webers are out of my budget for the next year or so but I would still like to upgrade from the stock Hitachi if worthwhile.

I have an A14 with a mild cam and head work, extractors and 2" exhaust.

What I would like to know from the experts is what would be the better option between the SSS L series twin SU's and a Weber 32/36 (Holley 180). Or is there another option?

Is it easy to get a manifold and linkages for the Su's? I know that I can pick up the necessary parts for the Weber or Holley from Autobarn.

I don't care about fuel economy as it is my second car but I do want it to run smoothly without flat spots.

Thanks for the help.
