Ok here is the plan.

I shall initially be keeping the standard efi setup and injectors, running off the normal ecu, And using the throttle bodies off the bike. Then after some research last night, it seems there is a huge choice of aftermarket injectors that can be bought from Jenvey. So once ive made sure everything works with the standard injectors i shall be eventually using the bike injector positions with uprated Bosch injectors and an aftermarket ecu to run them.

Turns out, the Zetec engine works best with quite a long inlet manifold and the injectors alot further away from the engine than standard. Making the fuel/air mix better.

Then to keep the MAF, i will have a look at a suitable plenum chamber
