You don't need a big alternator to run EFI but you do need a good alternator. EFI is susceptible to electrical noise so the alternator needs to be a late model design, preferably an OEM alternator. I use factory Denso alternators on my EFI cars. I use the 60 amp Denso unit on both of my cars.


So what is the original application for the Denso alternator you use? WIll it fit your brackets you sell for the motor-plate?
