I've read several places that the stock venturi and jetting size for the Zeniths initially were too small. I've also found a few recommendations jetting/veturi for modded engines. Though I haven't been able to find any recommendations for a standard 2.2T engine.
Some say that factory sizes runs just perfect, but as I'm rebuilding at the moment, and have to order new venturies and jets anyways, I though that I could as well order the optimal sizes.
I've seen that PMO has some recommendations for the Weber IDAs but not for the Zeniths.
Have any of you experimented and found the optimal venturi/jet-size for a standard 2.2T?
Here's a little picture of the beauty having a great time in the ultrasonic cleaner:
