Turbocharging a 140k miles car?

I wouldn't personally. Id rebuild the motor and put forged pistons and prepare it befor did turbo it

Well when you add a turbo onto any engine that wasn't built to be turbocharged you are going to greatly decrease its life expectancy... A turbo forces more air into the engine creating more power during combustion, and in turn wearing things out faster. I so no I would not put a turbo on that car.

HAHAHAHA thats funny lol come on man use your head you cannot put a turbo charger on any car with high mileage and expect it to " be ok" I mean really use your head please. the best thing to do is buy a car that has a turbocharger and live with that. Or spend 10 grand to rebiuld one the way it needs to be with a trannt and engine to match. At least this way its not going to suddenly blow up and cost you ten grand to replace it again. good luck though in your quest for the car of your dreams.save your money and do it right and dont waste your time doing it wrong

Do a compression test on the engine and if you can find a place to get the oil analyzed do that too. You may not need a rebuild to take a turbo. But if you do, it is cheaper to rebuild now while the engine is intact instead of after you scatter it in parts all over the road. Consider finding a low mileage engine to turbo, this is often cheaper then a rebuild.
