I'm running an A14 with a M10 Airesearch tubro, it has a strommburg CD175 carby. The turbo is from an early exa the same size as a T2. I've had a Hitachi Su on there and a 45 sidedraft
(pleanty of grunt) but I found that the ignion has been the main factor. I just had an electronic one from an L20 modified and it drives down low just like my girlfriends lancer, when I had the stanard one I had to drop the clutch to get it going. Hope this helps a little.
