Okay, Maybe i used the term 'conversion' quite loosely here but with the standard EFI manifold there seems to be enough room in there to swing your hips to the top 40.
Yes, the challenging part would be the plumping, but not anything too difficult if utilising sections from the original piping. I was looking at increasing the size of the piping to at least 2.5 inches to increase flow at top end and i could see the potential.
I only got as far as trying to fit the charger around my setup so i couldn't develop any templates as far as piping is concerned.
