gday all
I am finnaly at the stage where i trying to decide what bits to change on my engine and after little thought i have been thinking a webber would be approppriate. After trying to search the tech section and previous threads I still have a coulple of questions unanswered. Any help would be much appreciated.

The car will be a daily driver and iam just after abit of a power increase. What size should I be going for to use on a A15? and do i then need to change the manifold also? I would also like to know roughly how much i may need to budget for this. new or secondhand? Any help would really be appreciated guys cheers
