S5 n/a never had knock sensors, the housings are shared with the turbo however so they too have the threaded boss. it is an S5 engine though.
the braided lines tell me it was likely owned by an enthusiast. i see no signs of a rebuild though, at least not within 50k miles or 7 years.
the engine was probably replaced with a lower mile unit when the first one crapped the bed and a lower mile one dropped in. the wrecker merely went by the mileage on the odometer.
the fact that there is still rust on the flywheel tells me they are lying about compression figures and probably got them from alldata, where they get all the figures they give with their engines.
most likely if the engine had been turned at all there would be some oil dripping from the front oil line, i don't even see one drip under there.

if this is a local wrecking yard, ask if they can pull the exhaust manifold off (or if you can for them 10 mm for heat shields, 14mm for manifold studs)
turn the motor over by hand while shining a flash light in the exhust port, look in the exhaust port and see if you can see all the apex seals in there, turn it till one is over the port and push each one in and out make sure they are springy. every half rotation u should see one alternating front and rear till you see all 6.
if ones stuck, missing, broken, u see damage in there, rust, coolant, excessive oil(giant puddle) then something is wrong with the engine)
if your not usre what your looking for google for pictures of rotors, apex seals, pictures of exhaust ports

you obviously have never dealt with businesses.
as well, you don't find RX7s or random FC engines on craigslist very often anymore, or in the parts section here. add in the fact that this is an S5 and those engines are at the very least 5 times more difficult to find than an S4 engine. in my 15 years doing this i only accumulated 2 S5 core engines and about 15 S4 non turbos. those with S5's tend to keep their parts for spares.

if a wrecker is inclined to sell an engine they will try to get as much as they can for it, if they did in fact compression test it and it does have compression, the parts alone are worth the $700 asking price. but who's to say it wont roll a seal and kill the engine the moment you try to start it? one has to weigh options, if he has no engine to start with then $700 for a complete engine really isn't all that bad, but i'd recommend rebuilding it to be safe which adds another $1k to the engine cost. so really, the $2300 i quoted him for an engine including core, also isn't that bad of an option either...

You do have a good point about cars in the wrecking yards. There happens to be a guy reasonably local to me who used to part RX7s out, but I'm not sure if he still does. Last FC I saw in a yard was close to 10 years ago. They are getting rarer and tough to find. At this point, it's almost easier and cheaper to either buy a complete car or import an engine and pray you get something good. Then again, I don't think Japan got S5 NA engines.
