New engine?? yes? no?
I have a question. I don't have an RX-7 YET.. Actually I own a Dodge Stealth R/T TT, but I'm looking to add the RX-7 to my collection. I wanted to know what it would cost for a brand new engine? And would it be worth getting? I know nothing of these cars, which is why I'm here.. so please bare with me. Thanks in advance.

I wouldn't buy an new engine . You need to know the status of the existing engine first.
There are RXs for sale with relatively few miles on rebuilds/new engines. These, if properly cared for, will last many, many miles. Even RXs with high miles may have many more miles on them...it depends on how it was driven and cared for. I would spend money on reliability and performance upgrades...make the existing engine's support systems (cooling, vacuum, exhaust, etc.) healthy.
A complete engine (no labor to install) will range from about $2000 to $5000 (depending on what all you replace/get/modify with the new one).
For $2000 you could do all good reliability mods, boost gauge, exhaust, intake and any necessary maintenance (brake pads, etc.)...assuming you are turning the wrench.

sorry.. here's another question. I read in one of these posts that these engines burn oil as the nature of the beast... and that synthetics were bad because they didn't burn fast enough or clean enough or something, leaving behind deposits in the engine. When I get my 7 with a used engine, should I tear the engine apart to clean out these deposits? Is it fatal to the engine or at least harmful to HP if left unresolved?

Personally, my car barely burns any oil at all. I don't even think I've ever added any oil between oil changes or if I do, it's a very small amount. The whole deal with synthetics is floating around this section right now. Go check it out and do a forum search to find out more. If you want to hear my view...I don't use synthetic in my FD because...
1) It has never had synthetic in it before and I don't know how it will react.
2) I don't see the point of risking my engine just so I can have better quality oil in there.
3) Synthetic oils aren't revolutionary as far as what they do better over conventional oils; heck, synthetic oils only do a little more as far as performance goes from what I've heard.
4) I've heard many horror stories of people who start to use synthetic oil and have had to spend lots of $ to get things back to normal and I surely don't have money to burn right now.
That's my zero dollars and 2 cents on that matter. It would be a good idea to rebuild the original engine if you can do it yourself since it would be a lot less money and the car would probably run just as good as it would run with a brand new engine. In any case, good luck in your automotive endeavors.

If you ever need to clean the engine, you can drop in a bottle of motor flush for $2.5 before an oil change. It seems to work well on piston cars and it should be okay for rotary.
Basically, don't rebuilt the engine unless it blows. Also, before you put any mods on the car, make sure it's working 100%.
