I have some questions about the Jap Spec 12A Turbo.
Information is limited on it, but I need to know about the distributor.
As I understand, it's the ONLY Mazda OEM distributor that retards timing as well along with boost.
Can anyone give me some good clear pics of it, and
maybe the specs?
Do you set the timing like a regular dizzy?
Max Retard? Does it have a boost sensitive nipple?
Does it work well?
Any and all specific info you can provide will be great.
For now, I am switching to a blow through setup, while my Haltech goes back to AUS for repairs.
I plan on keeping the blow-through when I get a Series V convertible anyway (they are non-turbo in the U.S), so I want to know regardless of the Haltech
So I just want to know if this little distributor will keep my engine peppy, my timing dead on, and my engine from detonating.
