hi everybody im thinking about the hyundai efi system i need to know some details such as how does it work? does it need to come off the distributor for the injector pulse? does the throttle body work off cable or electronic? as much info as possible would be appreciated!

This is a bit brazen, because its my own sale, but how about a factory A-series fuel injection setup?

The Hyundai setup is okay but do you really want the intake pointing backward?

I started playing with one of these and decided I didn't like it. Two ports line up good, the other two are out by about 10mm and angled the wrong way. You can make an adapter plate but it's still rough (I think).

Like Chris says the throttle body will either point toward the cabin or need to be moved.

As with any injection setup it'll need a computer (ECU) of some kind to drive it.

As far as I know, not one person has ever completed the Hyundai EFI swap.

Possibilities:
* Mechanical throttle cable, just a like an A12/A14. The idle speed is controlled by the ECU (just like Datsun EFI) but not the throttle opening/closing (as in new Fly-by-wire throttle systems).
* modify the manifold bolt-pattern to fit (it is very close)
* Use a sock filter -- there's enough room. Alternatively, modify the manifold throttle plate (move to other end via cut-n-shut or JB weld)
* The ECU generates the injector pulse, not the distributor -- for all EFI systems. Some systems time the injector pulses to the cam position (often called [edit:] SEFI), but this doesn't increase HP instead it is for emissions.
* When you go to the wreckers, examine the Hyundai system. Does it use a CAS wheel in the distributor? If not, just use the Mitsubishi ECU -- get the whole Hyundai harness and ECU. But if it uses CAS wheel, search for a different year Hyundai. Or you might use a Datsun [ECU]] (which needs no special distributor) or an aftermarket ECU. Both can control other EFI.

Mitch built a custom plenum, but I did not hear if he ever got it running.

an NZ fella did it and had it running on an a14 with an ms ecu
