Considerations...
...Selling Your Stock Engine/Turbos/Trans...
...If your engine/turbos/transmission are in running condition, the best time to secure a
buyer is while they are still in use, where the running condition can be easily verified by
the prospective buyer. This way, there is no question about the compression, boost
pattern, seal condition, etc. There are many more RX-7’s than there are available running
engines, so a good engine can demand a premium price. This can go a long way to help
defray the cost of your V-8 conversion.

Recommended Work Area...
...The bare minimum should include a level, dry cement or asphalt surface to
provide firm and safe support for your jack stands, as well as to ease the rolling around of
the engine hoist and floor jack.
Engine Preparations...
...To minimize the down-time required to complete the conversion, the new engine
should be prepped & detailed in advance.
Removing Un-needed Parts & Accessories...
...Remove the alternator and stock motor mounts. After you’re done, now would be
a good time to pressure wash the engine, before it gets “too” exposed.
...Remove the stock exhaust manifolds. Use a 6 point socket, and be careful not to
break any bolts.
...Remove the starter, alternator, & intake manifold.
Preventive Maintenance...
...If there is any PM to be done on your new engine, now is the time to do it.
Replace any leaking seals or gaskets. If you want to install a new timing chain, oil pump,
etc, it will never be easier than now.
Transmission Preparations...
T-56...shifter removal will be required for installation. Drain the oil from your transmission to prevent a leak at the output shaft while the transmission is maneuvered into position.
Automatic...drain oil and remove the dipstick tube as preperation for installation. Replacing oil seals and installing a new filter is recommended.
Pre-conversion Preparation...
...Draining / Evacuating Your AC System...
...While your RX-7 is still mobile is the best time to have your AC system properly
evacuated by a professional. Not only is it illegal to release your refrigerant into the
atmosphere, it is also bad to expose the inside of your AC components to the outside
moisture laden air. A pro will be able to evacuate and seal your system, and at the same
time he can recover and save your rare and valuable R-12 for re-use later.
