After doing some research I chose to stick with making my first set from Honda motorbike bodies - the main reasons for this were:

• Throttle position sensor is the same as used on all PGM-Fi Honda cars.
• Build quality is absolutely first class.
• Many car components such as injectors, were a almost a direct swap.
• Integrated, automatic fast idle system is there if needed.
• Easily hooked up throttle.
• Naturally it's nice to keep everything made by Honda.

Whether or not these would perform well was unknown and naturally it would have been ideal to run these on a flowbench.
