Reliability.. Hmmm Stock vac lines blowing off is common.
Replacing them with silicone lines cures that.
Stock Air Seperator Tanks (AST's) can crack and cause you to lose coolant.
Bad news in a Fd.
NA rotary engines are pretty reliable.
Throw a turbo on there and you get problems.
Although if you keep up and ahead on maintence they can run with out problems. Thats not to say that they will though.
Parts are pretty expensive.
Apex seals are in side the engine so if they break under detonation you at the very least have to rebuild.
Which isnt cheap. If your apex seal damaged the rotor or the housing it gets even more expensive.
Alot of Fd engines loose thier coolnat seals around 60k some more, some less. Alot caused by the heat generated by turbos.
Downpipes and high flow cats help with moving the heat away from the engine.
Also a properly working and well ducted cooling system is vital.
Watch for excesive oil near the turbos (passenger side of engine bay)
Also at the rear main seal. (near the tranny bell housing)
A car that boosts properly should have about 10 psi on primary, 8 at the dip during transition , then back to 10 psi when
the secondary turbo comes online.
You can get a compression tester and run a compression test on the car.
Also you can pressure test the coolant system.
This link i am gonna leave is usefull so check out the site..
Lightning in a world of thunder
Other than that keep us up to date on the cars that you look at and we can help you along.
But the rx7 is totally an addiction accept it and get used to it.

The 3rd gen RX-7 is actualy cheaper on insurance due to the very high theft rates
of the Prelude. The amount of money you have to spend on the prelude to get it to
the RX-7's level of horsepower and handling is way too mutch. I did the same thing you wan't
to and it was one of the best performance upgrades I have ever made. Go from sport coupe
to pure sports car is an excelent choice. Have fun.
Only one draw back I can think of is FUEL MILEAGE!!
