Fitting a larger throttle body is not only unnecessary, it's usually brain damage. Skip it.
Thanks for pitching in Chris. Out of curiosity, what trouble have you seen with fitting larger throttle bodies to 911s?

I completed a rebuild about 5K miles ago, and it's shaping up that the only reason I'd need to break the engine down again is to machine the heads for knock sensors. Are there any alternate mounting positions for the sensors that don't require machining? Or is this a must-do in your mind?

-044 pump adapters available from TurboKraft,
Wow! Good to know the Carrera fuel system is up for the task. Do you think that Bosch 55 lb injectors will flow enough fuel? I'll plan to source the pumps and adapters from you as I get closer to the conversion date.

I was planning to use my stock Carrera cams. I've heard several success stories from engine builders that have used these cams including Supertec and AMS. I believe the grind is identical to SC cams, and that it's the cam timing that is different. Do you have any concerns on using Carrera cams?

Thank you!
