The weber IDA is a much different carb than the Weber IDF. I may be wrong but I thought the Empi HPMX was a copy of an IDF which is much more drivable. The IDA carbs are for all out racing and do better at full throttle or no throttle. The main venturi's my fit them both I dont know. Regardless, you will want to run 36 venturis in your carbs to get the full power your 2110 has on tap. I hate to say that the empi carbs don't have a lot of fans. I have heard more bad than good about them in the vane of all the important air passages not being drilled and other quality issues.
