I assume (since this is where the pictures are from), that you're interested in bidding on this ebay auction:

Algon fuel injection is a mechanical injection system which uses different injectors and no electronic controls.
To convert the auctioned system, you would need to get the manifold machined to accept electronically-controlled injectors. You would also need some means of pulling an average vacuum reading from each of the individual ports as they don't share a common manifold. This would mean fabricating some mini-manifold and plumbing to each of the areas under the throttle plates. At this late stage, you also would probably have to rebuild or refresh the throttle plates and mechanisms.
In addition to the machining for the injectors, and the fabrication for the vacuum accumulator, you would also need to work out some means of mounting other assorted sensors, like a TPS and coolant sensor. None of this is particularly rocket science, but it will add up.
AND, I've seen Algon manifolds go for $400. This auction is for a complete system, but if you're only interested in the manifold for conversion purposes, then you'd be buying a lot more 'stuff' than you really need. It's ultimately up to you though.
