I don’t know much about carbs or PMO but you can get from CIS to an EFI ITB set up for around $4000. Less if you can seek your CIS; I sold mine for $900 thus reducing my conversion cost. Of course, the sky is the limit and you could easily spend 10 times that much if you so desire.

RHD ITBs: $2400 with rain hats, ($2000 without)
Megasquirt: $659
Harness: $99
AFR sensor: $100
TPS: $30
Fuse panel: $20
FPR: $100
Fittings, hoses, wires, etc: $200
Temp sensor: $30

That’s a basic kit that doesn’t control timing, you can add that if you like or add it later.

Total cost $3639. So round up to $4k because I know I forgot some stuff and there you go. EFI/ITB for less than the cost of a set of core carbs or PMO.
