Does your set up have the ability to recover and recharge fast enough to run a car?
Use 12V 3Amps transformer to charge capacitor. It is like inverter, higher the amps of transformer
faster charging. use higher frequency (500Hz). See Optional circuit, it is inverter.

What type of step up transformer is used in you design?
Ignition coil, 12V 3Amps normal iron core xmer to make inverter. nothing special.

Would these be usable in your setup Cap70 ?
Please do not make things unnecessarily complicated.

After working through the schematic it looks as if only one spark plug wire will be needed!  Is that correct capacitor70?
No, Two wires one from capacitor and one from ignition coil. Diode on negative side becouse I dont want to break ignition coil wire.
Dideos on ground side create problem in engine, all body of engine is ground, so put diodes on positive side for engine trials.

Step up transformer?
Its ignition coil, internal diagram.

on/off Switch or just trigger for plasma?
you dont need to do this, if coil is on engine.
It is trigger for plasma.

Where does this come from ?
12V transformer priamary(230V), see bottom picture DSCN2716.jpg.
Ordinary 12V 3Amps transformer connected in reverse, to make simple inverter.

these are what you need guys, prices are in AUD.  probably need to wire a bunch of them in parallel to get 4-6 amps passed current and maintain 12kv blocking voltage.

Do not use parallel combination of diodes to increase current, It is critical to maintain same current in each diode.

WHY YOU GUYS WANT TO MAKE THINGS COMPLICATED AND COSTLY
PLEASE DO NOT CONFUSE READERS, i have seen other forums discussion is going on and on more than 15000 posts, new people get confuse

explain to me why diodes cant be wired in parallel

Connecting diodes in parallel will increase the current carrying capability. If it is possible to match the diodes so that approximately equal current sharing is achieved this should be done, however, in the event that the exact characteristics are not know sharing resistors (with associated losses) can to be used.

We are putting very high current, transient current during capacitor discharge is very high 1N4007 can sustane 20Amps of transient current, continuous current for 1N4007 is 1Amps, Think if any diode is have less resistance (due to it characteristics) than others maximum current flows through it, In practical
diodes in parallel work for short time slowly it degrades its performance and the same diode start to lower its resistance this increases more current flow through it this chain action damages diode, So you need to balance its current using series resistance with each diode, it is critical to get (and measure) that low value high current resistance. This is main reson why parallel diodes are not used. even connection resistance also plays very important role, for newbies in electronics why to make things complicated.

In series connection voltage across each diode is not exactly equal but the maximum differance in voltage is 50V this tolarance is given, so it will work fine
