Anyone out there interested in twin dizzy motor parts... (thought I would post here as there seems to be lots of 2 freaks here ).

Found some ex dealer parts brand new in the Mazda boxes... one eccentric shaft, a pair of rotors (6mm apex seal, but single side seal), a pair of 12a rotor housings with the 3-hole exhaust, a top mounted starter motor, sump, 6mm carbon apex seals and a 4-barrel carb (and some other misc bits and pieces).

Might suit collector - the owner is not giving them away... wants around $400NZD for each housing (I think that is $250/$275 USD each?), and about $200USD for the apex seals... not sure of the price of the other stufff... PM if you want to know more and I can hook you up.

Not of interest to me, I am 10a man 100%

I can ask there are piles of the "new - old" twin dizzy stuff.

As far as I know the 3-port exhaust ports were not used in the US. The US had thermal reactors from the start (correct me if I'm wrong).
Europe (here) had the 3 port housings.
I would be interested in the rotor housings at like 200$ each.
But... even the 3-port housings exist in different versions so I would need a picture of the exhaust port and coolant port.

Will get some pic's.

Do you know if early US 12a's run twin dizzy's and have 6mm carbon seals?

These rotor housings don't fit RX7 12A motors - two of the thru bolts do not align. Mazda here changed the bolt pattern in late 73 and there housings became obsolete when they moved to steel seals.

I know some people use the early housings on Rx7 engines. They just don't use two of the thru bolts.
On later Rx-7 engine Mazda used 15 instead of 17 thru bolts anyway.
Most used twin dizzy housings are in perfect condition (if not overheated) because of the carbon seals.
And there are still carbon racing seals available that don't damage the twin dizzy housings.

Early US 12a's use twin dizzy's and 6mm seals. I don't know when they changed from double to single side seals.

actaully I need an RX-2 dipstick AND a water temperature sending unit. The one on the thermostat houseing, not the top of the center iron.

I need these pretty badly so I'll pay a fair price if you have them.

thanks in advance
