I'm sure you can - my EFI is using newer style relays and mounts in the engine bay. You will need to rip and replace, or leave in place and add to all the existing mounts I suspect ... not sure if anyone offers a ready made solution. May want to contact TurboKraft and ask them - they seem to be on top of all trends related to more reliability and performance.
I think just upgrading the fuel pump circuits and the various overboost and ignition relays, etc. would be all you need to do, maybe.
You should just save up and swap it all for EFI
