I'm running a 1.8 silvertop zetec with ZX6R carbs (no tps) and megajolt. As Dave says you just need a coil pack, use the crank position sensor and EDIS 4 unit. I am using a MAP sensor with my engine due to the lack of TPS on my carbs. I have just drilled and tapped my inlet manifold with an M3 tap and then fitted some welding tips drilled out to 2mm which are also loctited in place to make them air tight to the manifold. I've then teed the 4 vacuum feeds together and then they go into one of the plastic fuel filter housings which acts as a damping unit to smooth out the vacuum signal. This is then attached to Megajolt.
Using a MAP sensor has a few advantages over TPS in that it more accurately shows how the engine is breathing as TPS doesn't show load, only throttle opening. However MAP can be more of a faff to get a smooth signal from.
