ok its not cheap , you'll need a good £800 at least , also to set up takes a lil work , also you need to bypass the fuel pump im not sure on golfs but id imagine you just remove the one underneath and use a hose in place , the one in the tank would need a similar mod as my 205 had , which was to remove and replace with a pick up pipe of similar length , you then install the facet fuel pump as near to the carbs as posible (the space where the air box went is ideal.
you need 2xweber or delorto 40 carbs , a inlet manifold , a facet fuel pump , a fuel regulator/filter , fuel piping and union connectors , a small filter for the breather and two large filters for the carbs. also if you buy them brand new or second hand there gonna need to have the right idle and main jets also venturis need to be the right size. this is what cost me the most to get right , i spent a fortune rolling roading it , changing jets till i got the best performance. it spent the whole day at a weber specialist , which aint cheap!. is it worth it? , yes! , my 205 on twin webers was a arse ripping laugh , it never failed to make me smile when i heard those carbs roar , its worth having a race head built for them btw , i had a 275 cam and a gasflowed/skimmed n port enlarged head. my low to mid range was scary. 6 sec 0-60's were no probs , fuel wasnt all that bad either
, only prob with the golf is its inlet manifold is on the back . imo 205's are much better suited to carbs because of there orientation.
