Ignition

Distributor: because it is on the back of the head, some mod will be needed.

Cut hole in firewall

OR, use an inexpensive Crank Trigger ignition with coil packs

OR, use a right-angle distributor from a circa 1987 Suzuki G13A along with custom adapter plate

Suzi-tech at Thornliegh made the dizzy and it cost a fortune. If I was to do it again I would just cut the fire wall. I think you can use a Mazda cap which gives you more room.
