 Description as above but:
-It's possible, and very easy, to replace the coil packs without taking the whole coil assembly out, as described above. The two coil packs are held to the bracket via two 7/32 inch bolts each (visible in the above pictures. One is between the ignition lead connectors. The other is on the opposite side of the pack). The black plastic base of the assembly, that contains the wiring, is held on by those same bolts, by compression. There's apparently a grommet or insulator in the holes in the plastic base, because the bolts don't fall out when you loosen them, which is nice. Leave the three wiring harness connectors connected, and the wiring base will pretty much stay where it is when you remove the coil packs. There are a couple of built-in studs on the base that go into holes in the bracket to line it up so it all goes back together easily.

 I used a short ratchet handle, with a 4 inch extension to easily reach the bolts and have room to turn the handle.

-This section relates to the turbo ignition system: It is a Direct Ignition system which does away with conventional distributor. It uses two separate coil packs and the 'waste spark' technique whereby cylinders 1&4 and 2&3 are provided with a spark every revolution i.e. on both the compression and exhaust strokes, the latter obviously serving no useful function. The two coil packs are mounted on a backing plate. The coils internal ignition module controls the spark advance at cranking speed but when the engine speed exceeds 800RPM, the [[ECU]] takes over control.
