I've been out of the VW scene for a No of years and I was wondering if there are any good aftremarket EFI kits out there to convert a type 1 motor from twin webers to EFI.
Any thoughts.

Here are just some of the sites that sell aftermarket ECUs. As far as "kits" for VWs there is generally only 2:
Jenvy, and

Neither of these kits use a single throttle body. It is widely accepted that for a street car a single TB design is far better than any quad TB design (look similar to twin carbies). And the CBPerformance ECU is petty prehistoric.

There is a good EFI forum here http://www.shoptalkforums.com/viewforum.php?f=23&sid=769d8266a1fb98c56f757ae1...

There you will find all sorts of really good info. such as designing your plenum and runners. Some believe that the quad TB is a better way to go. Read, read and read and learn heaps as you go along.

There are a couple of really good threads here about home-made EFI systems, using mostly 2nd hand stuff off Holden Camiras of all things! Do a search and you'll find them.

Thanks I'll start reading.
