i am currently running a webber on my 1.3
i fitted this with no problems, it bolted straight down onto the existing manifold. my mk2 is a 1990 H reg.
i have not uprated the fuel pump and it works fine. the only slight problem i have is that if it is not used for say two days it runs very strange, as if it is struggling for some reason
this could just be a problem with my set up of the carb. you will notice the difference straight away. the sound alone is worth it, even if it is only a 1.3
i am also running a K&N bolt on air filter.
i will try and up load some pics tonight.
