What is the reliability of a turbo engine vs its non-turbo version (Mazda 3 vs Mazdaspeed 3)?

Answer 1

The non-turbo would probably have better reliability just for the simple fact that there are less parts.

Turbo's require a little more attention to maintenance. Also, there are some things you can do to aid the reliability of a turbe. You can let the engine idle for a minute or so and let the turbo spin down to a slower speed before you shut it off. Once you turn off the engine the oil pump stops supplying oil to the turbo and it is still spinning. So try and have the turbo spinning as slow as you can before you stop.

Answer 2

When it comes to reliability on the speed 3 it all falls on the maintenance. If you take care of the turbo such as putting the right gas in the car, and routine scheduled maintenance the speed three is the car for you. It is the fastest front wheel drive car made today and a blast to drive. And when it come to the regular three you have two option the 2.0 or the 2.3 liter engines. And again the regular 3 is still a blast to drive and a very good car. And just so you know there was a test done over the past ten years on the top ten car manufactures on the amount of maintenance required on a vehicle during the time of ownership, and Mazda came out on top. So all in all it your choice on weather you want the speed or regular 3, but you wont go wrong with either choice.

The best launch technique is to rev the engine to about 2500 rpm and feed in the clutch before going to full throttle. This produces almost zero wheelspin which is necessary with the 3's massive torque. Wheelspin launches were considerably slower. Upshifting at 6000 rpm also improved times as power falls off seriously after that.
To celebrate the successful and well-regarded Mazda 3's three-year mid-cycle refresh, Mazda is introducing the Mazdaspeed 3. This hotted-up 3 combines the turbocharged 2.3-liter DISI direct-injection four-cylinder engine (making more than 250 hp in this guise) from the long-delayed Mazaspeed 6 with the 3's smaller five-door hatchback body and front-wheel drive only (the Mazdaspeed 6 has all-wheel drive). Top speed is limited to 155 mph and Mazda claims a 6.1-second time for 0-100 km/h (62 mph). The suspension setup is significantly stiffer than the standard 3's (which is already no marshmallow), but it remains to be seen how well this chassis will handle the massive 280 lb-ft of torque; the few European hatchbacks with this amount of twist are pretty unruly, especially when equipped, as this Mazda is, with a limited-slip differential. We're bracing ourselves for the torque-steer
