This is the amount of space I have I have tried to examine some options for replacing the TFI distributor, which does not fit in the space below the frame rail. Later model Fords adopted a Distributorless Ignition System (DIS) which used a crankshaft angle sensor to run the ignition and batch injection systems through the computer (ECU). This system replaced the distributor with a "stub" which still engaged the aux shaft and drove the oil pump in replacement for the distributor but it didn't provide any ignition signaling trigger, that was provided from the front of the engine. Later, Ford developed EDIS with a Cam Synchronizer which mounted on the stub from the aux shaft. Then the engine design was changed in 1994 and any system beyond that was incompatable with my turbo engine. I like the idea of replacing the distributor with something that will work or even upgrade the operation of my engine. I'm thinking mostly of using a PiMPxs ECU that functions without the TF...
