Yes, I agree that the SU's are a better choice if you are going to set them up properly (professionally rebuilt and dyno tuned). I've run just all the popular types of induction on my A15, stock Hitachi, Weber 32/36 DGV, GX dual SU's, and 40mm Dellorto's. I think the SU's were the best for all around performance and reliability. They performed a lot better than the 32/36 Weber and got the same gas mileage (~35-38 miles per gallon), and while the Dellorto's definitely give the most power, the SU's weren't far behind and the gas mileage is worse with Dellorto's and it's constant upkeep. The SU's once set right don't require a lot of attention at all. I cheated mine and instead of going with a different needle/spring (not much SU support in the US) to set my mixture richer, I just thickened the damper oil and it worked great! They really are a simple carb when you learn them too.

I'm still anxious to see how a properly tuned EFI setup would go on the A series though in comparison to the rest. My poor A15 that I've been running for about 8 years now has never been truly "tuned" with a dyno or wideband O2. I bet there's still a lot of power to be had out of it. Maybe when I return to the US I'll give it a shot.
