The simple facts with turbos,
1. Turbine is proned the early failure due to the tremendous temperatures they operate at and also get impeller wear and bearing failure.
2. Internal engine components are subjected increased stress, due to the increased power made by the turbo.
3. Doing remapping and increasing HP out to the turbo, you have to make sure by doing so that you are not exceeding the design limits of the engines internal components.

1. Wrong, they are not anymore prone to early wear out than any other component in the motor.
2. How is this any different than any other power adder? Also the motors are built to higher tolerances than the OEM spec, this is what professional tuners take advantage of when they tune.
3. Again if done correctly the the motor is fine, but thats true about anything. Reminds me of the old days when these young kids would get manual boost controllers installed and manually crank the boost up then blow their motors/turbos.

Sounds like your family is cursed. Turbos are no less reliable than NA cars. Most get better gas mileage. Diesels are more reliable than petrol and last longer. My TT Supra converted to a single running 29psi ran without issues until I sold it at 90k miles. My Evo 8 running 22psi ran perfect. Every one I know has never had any issues outside the norm with a turbo engine and almost all have been modified.
Sucks you and your brother had problems, but that's far from fact to justify making a blanket statement like that. I will agree, however, that tuning needs to be done smart. Exceeding the threshold of your engine's capacity will of course cause damage and things to fail. But that's true for any type of motor.

I completely agree. This sort of thinking reminds me of how people feel towards running Nitrous. People that do not know how to properly do it will blow their motors however done correctly its 100% fine.. Most times you will hear people say its dangerous and how a cousins, brother, uncles, sisters, person she knows had their motor rebuilt due to that evil Nitrous.... |
