JDM's carburation to EFI

I've been looking on ebay at JDM engine's, and some of these are listed as carburated. Is there much work involved in changing a carburated unit to EFI?

Anybody have an opinion as to whether it is safe to buy a JDM engine on EBAY, they seem to be going for as much as $200 less, before duty and conversion (I'm Canadian.)

If you have bought a JDM engine, could you tell me where you got it from?

as long as its a G10 late with the small valve cover (not the wide black one) all you have to do is use your intake mnaifold and exhaust on it and it will drop right in

Bought a JDM engine from makoto auto parts (on ebay). Mine happens to be an early model (86) with the wide black valve cover. Swapped over the intake/exhaust manifolds to keep all the electronics/sensors as the JDM version was a bit different. 10K miles later still going....
