Looking for an EFI system for a V8 engine.

[Evert Rosseel]

I just noticed I forgot to mention in my original post that the 
gas injectors are already available.
We only need a system to control them.

Also, can someone post the fax number of the firm that makes the MOTEC 
system, or a dealer in Europe ?
