While this is on my 3.6 NA engine and not on my Turbo, the same COPs could be used for both. I am using Toyota coil packs 90919-02246 (from several mid 2000's V6 engines). Cheap on eBay.
The standard Toyota seal under the head of the COP is too thick and too big in diameter to suit the 964 rocker covers so I am using a smaller rubber seal to close the gap.
I made up a bracket that is fixed to the lower rocker covers to secure the lower coils. The top coils sit in place securely without fixing bolts.
These coils will be fired by a 5V ignition signal from Megasquirt MS3X.

I have just received parts back from powder-coating so I fitted them together loosely for pics. "Dirty" pics below are of engine pre-assembly before plating and powder-coating.

1988 Carrera - 3.6 engine (with ITBs, COPs, MS3X) and a whole set of turbo body panels waiting in the attic.
Day job ...
