Andy - for compariosn - have a look here -

For a pinto for example the kit they supply consists of -
Megajolt V4 ECU
New coil pack and connector
New crank sensor and connector
Refurbished EDIS Ignition module
Universal crank sensor bracket
Coil pack bracket
Loom kit
Univeral 36-1 trigger wheel (custom wheel included in xflow bundle)
Set of 8mm silicone spark plug leads
All software and cables required to tune the system and maps for a wide range of engines
Just about every item there is essential. You can pick up EDIS units secondhand and buy a trigger wheel and fit it. It's quite a lot of work and then you need to tune it so allow some rolling road time or someone who has a good 'butt' dyno.
