    havent my self but,youll need to make a heatshield for the carbs,and would be wise to have the manifold wrapped as the carbs will sit above.
    not sure how u go on with clearance,may foul the bulk head/rain tray.
    not a hard job really,just a case of placing things,running pipes,and bolting up the manifold and carbs.

    Clearance from the brake servo will also be a problem.
    I know a lad in stoke who ran a 1.6cl on twin 40's and the carbs were very very close so on a gti servo they would be touching.

    IMO
    You need to think about either a different brake setup or new beetle crossflow 8v head so you have plenty of room for the carbs at the front and the exhaust manifold at the back.
    Drawback with the new beetle cylinder head AFAIK is price of the twin carb manifold. (About 150 or 250 last time I checked)

    my car is actually a 1.3 with a 1.8 engine 1.6 top and god knows what else so i think it will have to be pray and hope that they fit and thanks about the heat shield i already guessed the heat from the exaust may heat up the carbs too much though

    Hey-ho, I'm "That lad from stoke".....

    Yes, twin 40's will sit on a 1.8 (non GTI!) without a problem. Indeed you will need a heat shield for the exhaust manifold, but its only seriously needed if you have an original cast iron exhaust manifold. if you have a stainless manifold its not too much of a problem cos the heat dissipates more quickly, and heat isn't retained as long. The heat retention caused problems, cos it would boil the fuel in the carbs if I was standing still, not good. HTH.

    indeed. Just cos there's discs at the back n so the servo has to be bigger.
