Hi,
Yes, the Gotech works great with the Zetec bottom end, I assume you'll use the 36-1 crank trigger wheel??
With the injectors, you need to size for the projected power output, but I guess dark greens would cover it!
If you get rid of the dizzy in the head, you can run the zetec coil pack, and fire it directly from the ecu via three wires, (power and two ignition outputs)
Doing this will give you a very healthy BIG spark, as the Gotech direct output has more punch than the typical TP100 type ingition modules.
If you keep the standard dizzy and coil, you can fire this direct too!!
