We use these on the V12s and high hp mopar motors in the shop. I figured they could be of some to Rx-7 guys, especially those who store rx-7s over the winter or have turbocharged rx7s. The unit fills alls the oil galleries, motor and turbo bearings with oil to prevent dry starts.

I seriously doubt the turbo bearings have oil in them on startup, being return line is gravity fed. I figured the rotors would have some oil in them as they can't drain anywhere. I've always been told all bearings see most failure from startup, and rx7s bearings do wear, fail and some do spin. If you are interested, pm me and I will set you up.

Just stick your finger into the turbine BEFORE IT STARTS TO SPIN and just wait for the oil pressure to come up. It only takes like one or two seconds in a rotary unless the oil cooler is totally empty, such as after a cleaning or whatever, in which case you wouldn't try to rev it anyway.
Mike is right. There's no point in worrying about it.

Thought I would bring this back from the dead. So far I've seen almost all bearing wear eliminated from dry starts using these on the cars in the shop. Motors that sit for any amount of time do squish out all the oil sitting on the bearings, and it does take several seconds to get oil pressure up, meaning you are wearing away at the bearings...
Also nice for new engines

Elliot could you explain how this bolts to the motor and works? Not to sure how on a rotary here. This would be nice to any motor as this is the highest wear time a motor will ever see.
The old Buick grand nationals used to do this kind of. They had a delay when you crank the car it would not crank for like 6 seconds. This was to allows oil pressure to build up in the turbo and motor before spinning up. After the time was reached they would crank right up. You could bypass this by turning the key back then forward. It was a big complaint in the dealership from customers who didn’t understand. So GM made a press release and a fix latter on.

Did they have an external oil pump or just using the oem oil pump, ie; disabling spark and still turning over the engine?
You have to plumb a line into your oil pan, and a line into your feed system.
Its not a drop in system, it could be if someone was willing to pay for it
