from what i heard, its better to s/c an auto. both a turbo and a s/c will shorten the live of your engine but a s/c will be safer for an auto.

What would make it "unsafe" to turbocharge an AT? Why would the engine deteriorate faster if the car has an AT than a MT?

No, Marty - the engine is the same


Transmission is different and it's a common belief that manual will withstand greater increase in torque than AT would. Plus manual is easier and cheaper to beef up than auto.

So, how would that affect the longevity of the engine? Wouldn't that indicate that the transmission would fail, rather than the engine?

Exactly. No difference in engine wear between auto and manual, at least to my knowledge, but transmission might be an issue. And an expensive one.

Well, that's why I was asking...earlier, someone said that it would shorten the life of the engine, and I wanted to know why. Anyone else have information on this?

Engine is fine; it will wear off the same way manual's engine would.

But the tranny would be completely different. The AT won't be able to handle all that abuse and power and fail quicker. Normally if the turbo comes with the car, the mfg had tuned the turbo and boost at a reasonble level. But aftermarkets would be hard to say.

I dont think Some of these guys understand what "Big Bear" had posted about turbos and super chargers. He is saying that a super charger or a turbo will shorten the life of your engine.

Now on to the response-
A SC or a turbo will not shorten the life of your motor. As long as you install properly and make sure that you know how to tune properly with the proper anount of boost. Of course you will always fall back to the old golden rule of being fast....... The more power you have and the faster you go, The higher the chance of breaking something and losing reliability.
