I hope you don't mind I added to your answer. Check "Haynes Repair manual" page 6-9. Special:Booksources56392 409 9.
i read a forum where they dug the "Cread@r" OBD II reader if your car is c. 1996 & newer. About $50. on eBay and overstock.com . It shows the code number when plugged in and clears the code when the problem is fixed. Has the OM with it and a list of the diagnosis for the code # retreived.
AnswerI can tell you from experience this is not a d-i-y project. It is best left up to a independent repair shop that is familiar with this nature of repair. Maybe and I mean MAYBE, you'll get lucky. If you screw up and create another problem, the more it will cost you at any repair shop. Most likely you will end up replacing somthing that didn't need replacing and cause another problem attempting to fix the intitial problem. I have seen this too often. AnswerFirst, you need to get the trouble code that caused the light to come on. This Code will start with a "P" followed by 4 numbers. This light is always an engine performance concern. The only way you can "screw up" your car is if you start making unadvised repairs. Some auto parts stores will scan your codes for free if you indicate that you will buy the part from them. However you won't know what part at first. Always get advise between eacxh step in repairing your vehicle. Also, don't let novices scare you away from repairing your own car. It's not rocket science, but with the right information the sky is the limit. :)Some parts stores such as Autozone, Pep Boys, Advanced, etc. will read the codes for you and may even have scan tools for rent.
With no idea what you are doing it would be a learning experience and an expensive one. I would suggest purchasing a shop manual for that vehicle and owning a full set of tools and some shop equipment.
I am sorry but you do not without the proper equipment.
The type of equipment you will need for doing a engine replacement is a 1 ton lift. Now you will be able to get the engine in the correct place without getting injury.
Not without extensive (and expensive) modification
Purchasing a vehicle in parts, or for parts can be done at your local junk or salvage yards.
The cost of a Mazda RX7 turbo engine will vary depending on the country one is purchasing it from. In the United States they cost around $1500 new or cheaper used.
Not without seriously extensive (and expensive) modification
Not really. Without oil, the engine will soon have metal rubbing on metal, which will cause parts to go hot and seize. And that means engine destruction and expensive repairs.
Not likely without seriously expensive modification
Airplane propellers pull or push the plane thru the air. Without them, the plane will not move. Without them, you do not HAVE an airplane- you have a large, very expensive paperweight.
There are a range of engine test equipment available in most very good Vehicle parts retailers
