You could go custom, and modify the intakes for a set of webers made for the VW. This is something I am curretly planning on doing, after I find a more aggresive cams, larger vavles, and deck the heads off course.

If your not planning on doing any work to the heads, you most likely won't need that much fuel in the first place. It would only be used during the highest of your RPM's. Having your heads pull from a common intake (single carb) and meeting in a Y pipe creates an even suction flow in your motor, and actually helps scavenge exhaust from the opposite cyclendar in the fire order. This also pulls air into your carb more evenly. What does that mean, more torque in lower RPMS! If you haven't already tried a single weber with a free flow air element, I would suggest that. Also an electronic igntion system that fires multiple sparks and has a longer crank duration. MSD offers an off road option that is reasonably priced, and apoxy filled for the harsh environments.

 

Hope this helps,

Although they are rare, they do surface every once in a while, but there is a dual carb manifold that was not available here, but sometimes can be found.

 

I believe that SJR is developing one, which would be cool.

 

There is a way that you can run the SPFI on the EA-81, just need to rewire it, and add the EA-81 timing gear to the EA-82 disty, but other than that it should work just as easy as on an EA82, and more power than a webber to boot.

I bought one not too long ago.I searched and searched for quite some time.They are really hard to get.It is now my baby!I asked a bunch of people about them.And called numerous salvage yards and suby specific yards around the US.Good luck finding one. I am sure you will find one but you must be patient.
