This engine won many 24 hour races before the rotary was
 heavily handicapped.

 I would buy injector blocks like those, seats unmachined so
 the end user could finish then to suit their own injectors.
 Anyone else interested? Jeff?

 Mechanical injection ?

I'm talking about the design of the piece that holds the injectors,
the seats radialy centered on the intake tube not talking about
using mechanical injection.

What is the matter with this design? It was done this way to simplify the fuel rail. You need a minimum of two injectors per p-port runner to get fine control over the amount of fuel injected over the power and RPM range. The RX8 engine uses three per rotor.

Some of the fuel may impinges on the side wall but it evaporates eventually and is not lost. The vapor eventually goes in the engine.

Matter can neither be created nor destroyed. It is a law of physics.
It is just not a good idea. IT IS THE LAW! :)

To "crack" gasoline into other constituent molecules takes a lot of heat. The intake  manifold usually runs ice cold due to evaporation.
