I just accquired a 73 datsun 1200 with a a12 engine in it. I was wondering if it is possible to put a mazda 12a rotory in it. any help would be greatly appreciated. Thanks.

hey im just in the prosess of doing it now. im just trying to get QLD transport to let me do a 12A turbo. N/A will be easy as for mod plate. What do u want to no?

what is needed to do the conversion. what do i need? new transmission, engine mounts? Thanks

i don't mean to sound like a cynic - but you'll need a new everything.

new engine mounts, new gearbox mounts, new shifter hole, new radiator mounts and position for the oil cooler (bolts to underside of radiator), new tailshaft, new brakes to match and if you're not nice, a new diff!

depending on the final position of your engine, you may have to either scallop and re-strengthen the crossmember, or custom make a new sump pan to get the engine lower in the vehicle. why? to save you having to fabricate a new tranny tunnel to take the gearbox bellhousing - an engineering nightmare for a street car in QLD or VIC.

the great things about rotaries are, you can effectively ditch the sump and setup a dry sump system due to the rotor not requiring the sump in it's factory position at all - so you could remove it and fit a reservoir elsewhere and a nice PHAT piece of 20mm aluminium plate to strengthen the motor and stop the rear plate shifting under high load.
