please read the FAQ before posting:
How long does a rotary engine run? Do I need to rebuild my engine?
Most 13Bs can last over 150-200K miles, while most 13BT engines usually last 125-175K miles, but remember that regular proper maintenance for the engines entire life is required for higher lifespan.

I don't think this question can be answered; no one, as of yet, has ran a stock turbo car until it has died. insted, some kid will get it and crank the boost up to 10000psi without any fuel mods and kill it long before its time.

IN my possession is an 88 10ae with 192k on the ORIGINAL turbo engine, and it still runs...70-80 compression, floods, smokes on startup, burns coolant, idles rough, and builds little to no boost..but, its still a running driving car.
This is the highest mileage I have ever heard documented for an original turbo engine.
As for NA's there is a guy on the FC3S list who got 375k from a 90 GXL before the engine **** a water seal, IIRC. The car now sits at 41xK miles IIRC, on a new engine.

Apex seals die on both NA and turbo cars.
ITs often hard, even as an experienced rebuilder, to differentiate between the reason for seal failure. Several things contribute..
-detonation/lean condition
-timing off
-carbon buildup
-apex seal wear
The end result of all are pretty much teh same...the top third of the stock apex seal winds up breaking or rolling completely out of it's groove in the rotor, because of the fact it has worn down too low (usually around half its original height). Obviously detonation or carbon buildup can aggravate this condition, but regardless of teh theorized cause, the result is a torn up rotor and rotorhousing, and in turbo engines, sometimes 2, as the pieces of seal can hit the turbine fan and get thrown back towards the engine, entering the opposing rotorhousing exhaust port and bouncing around inside there.
