it would be over a grand, when you buy the engine and all necessary parts, then labour if your getting it done proffesionaly, wouldnt even bother doing it as its a lot of money to risk not working.i was told a 2.0l 20v turbo from a coupe would fit straight into my stilo, and even then cars nowadays are all run by electrics, it would have taken a long time to re-wire the whole car and then get engine mounts manufactured and then the exhaust would need to be changed etc etc, fuel pumps and upgrade brakes and suspension, its crazy, your talking £3000 to do it properly, waste of time when you'd be better off buying a faster car to start off with, thats why i'm not bothering with turbo's and big engine mods, just wanting rid of the car so i can get 8 cylinders, 3.2 litres, and two turbo's as standard to play with.
