Dan is a great guy and offers a great product. His work is second to none when it comes to modifying the factory throttle body.
I personally would not go any smaller then 70mm... Its the same price... Bigger is better in this case... to a point of course.
I have a used 70mm Fastman throttle body on the shelf that I removed to install my F&B 72mm throttle body.
