does anyone know where i can get a video on how to take out a 3rd gen Rx7 motor and put it back in. You see i bought an Rx7 without a motor nore tranny and i want to put one in. And one more question are all the 3rd gen rx7 computer harness the same
EXAMPLE: Is a 94 rx7 computer harness the same as a 93 rx7

 

It would be a good idea to get your hands on a workshop manual for the 3rd Gen.
I've taken mine out twice.

Remove air box and all hoses.
Remove pipe work to throttle body and from turbos to intercooler.
Disconnect Oil Cooler Lines from Oil Lines coming from motor
Unplug wiring harness to computer inside car.
Unbolt downpipe or precat
disconnect air hose leading from back of engine down to the catalytic converter
unbolt and remove starter
Unplug four plugs from the wiring harness that are attached to the transmission
unbolt the transmission from the engine.
**the pressure plate is secured to the flywheel and will not release it unless you take off two plates of the transmission so that you can stick a screwdriver in and make the pressure plate release the flywheel. For this you need the workshop manual so that you can see exactly what you need to do to release it.
disconnect water hoses
unbolt engine mounts from the crossmember.
Remove it with a engine hoist.
I think that's about it.
