Carburetor swap
- Thread starter ZEB
- Start date
The Lima 2.3l engine was used from 1974(Ford Pinto) to around 1985 with carburetors.
You would need to get an intake and carb from those years, you would also need a fuel pressure regulator to drop the pressure down to 7psi, and an Oil Pressure switch added for electric fuel pump operation.
For Spark you will need a 2.3l Duraspark distributor, it has vacuum advance, and an HEI module to run the system.
Duraspark modules are OK but were prone to failure as they got older, HEIs are cheap and new.

The worst fuel injection system is more trouble free than the best carb system, just FYI.
And it gives better performance and economy.
But I do understand the need for less complicated systems
Carb and HEI are about as uncomplicated as you can get

Just FYI on electric fuel pumps and the Oil Pressure switch.
In the old days mechanical fuel pumps weren't really much of a danger because they were low pressure and would shut off when engine shut off, like in a rollover or accident, or hose broke, engine dies with no fuel
Electric fuel pumps are good but they present a problem in a rollover, accident or broken hose if they keep pumping out fuel, the danger is obvious.
So they have 3 shutoffs, the key of course, and then the inertia switch, it is suppose to "open" and cut power to the fuel pump(s) in an accident or rollover, it is basically an impact switch.
And the 3rd is the computer(which you are removing I assume), if engine RPMs drop below 400 then computer will "open" fuel pump relay cutting power to the fuel pump(s).
With a carb there is a float bowl that always has fuel in it for starting the engine, so fuel pump doesn't need to come on with the key, same as mechanical pump setup.
An oil pressure switch closes when there is oil pressure, engine running, and opens when there is no oil pressure, engine off.
So you add the oil pressure switch to the engine and use it to run the Fuel Pump Relay.
Very easy to wire.
And that gives you the safety back to the system.
