Scirocco Register

Hi Guys

I need your help on something...I used to own a scirocco MK1 back in 1984-5 and had problems with the old Pierburg carb. I replaced it back then with a weber and from memory the difference was great. I now run a 1781 Gt II and although the original carb is ok it does not exactly pull up any trees. Do you think it is worth fitting a weber 32/34 replacement or am I wasting my money?

Thanks for any help on this.

the weber is much much easier to set up, so you've got a better chance of getting it running right, particularly as there are so few people left who actually know how to properly set up the pierburg. that said, the pierburg is a far more advanced carb, and is actually slightly bigger so when it's running right you will have more power

I had exactly the same problem when I got my car earlier this year, I found the original Pieburg vacuum system on mine was shot. I believe that when they are set up properly & working well they are a good carb, but I'm a Weber man & I swapped mine out. I would highly recommend the Weber conversion, mine's a different car & I'm sure it has added a few BHP. Some poeple argue this point & without a rolling road I can't prove it, but throttle response seems better & mine certainly pulls like a trian. I'm lucky to live around some private roads that I have access too & mine will go over the ton with no problem now, where before I could get 90 max. Infact I run out of revs before speed!!

Note, this was tested on private (tarred) farm roads

get it done, my gt II has been transformed by the weber, so much more responsive

My recently purchased GT2 has a Pierburg carb that was said to be running perfectly.

The car clearly hasn't been running perfectly. I wanted to eliminate any fuelling issues and did find blockages in the pickup in the tank. So I thought I rectified this but still getting intermittent problems. From what I have read the Pierburg Carb 'when working' is the better carb. However there are so many variables with the carb, vac hoses, automatic choke, various heaters,wiring, inlet blockage, some sort of relay etc, etc.. Then you factor in problems that occur the full length of the fueling system, corrosion, collapsed/perished pipes...

So I have little time to go through all the Pierburg literature, try and make sense of it (tried before) and then the fuel system.

I am therefore looking to fit the Weber that I had previously on my last Rocco this weekend and just hope that it rectifies the problems I am having. I understand how they work and love the simplicity of the manual choke. You can whip out the jets in minutes and control the fuel and idle very simply. I just prey that it doesn't become problematic when doing the swap.
