F27VX
Firstly can you fit an IDA or get hold of the outboard manifold from a Fiat Spider Europa VX or even a Volumetrico which would turn the carb the right way round for nortn south? I have seen on you tube the use on Fiat Croma IE parts on a VX engine, but getting the injectors into the inboard manifold is not straight forward. I know this because I am doing it on 2 engines now! The easiest option would be to find a Plenum throttle body with injector ports and to graft this to the current manifold.
Or you can get DCNF pattern throttle bodies from Jenvey. You would use a 44 with a pair of large injectors in the throttle body ports and a TPS (throttle position sensor). You would of course need a suitable high pressure pump, correctly sized injectors, fuel rail, FI adjustable Pressure regulator, TPS or ManifoldAirPressure sensor, AirTempSensor, CrankPositionSensor & 36 -1 or 60-2 Trigger wheel, WaterTempSensor, ECU and wiring and high pressure FI hoses. With all the sensors in place and the ECU wired you would need the car mapped by someone who knows how to program your ECU so find them BEFORE buying a cheap ECU. This is all do able and I am in fact building both an FI VX Montecarlo and a FI Volumetrico Beta Spyder, but I believe modifying your manifold to turn the carb the right way round for the float chamber is definately first option if you cannot buy one from a north south engine set up.
