Hi Scotty!
you have said recently that turbo’s wear out the engine quicker than non turbo engines. With Toyota going to turbo’s with the new 4 cylinder engines for emissions reasons does that mean that the turbo/ engine system is better than it was and those problems are solved? Thanks!
Of course as they make more of them, the technology will improve. But they will still never outlast a naturally aspirated engine.
It depends on how well the engine is designed to take the stress. (My turbocharged engine is doing just fine after 25 years and over 365,000 miles.)
Which make model and engine is this?!
1997 Saab 9000 with 2.3 turbo. Say what you will about Saab but they knew how to build turbocharged engines. (Their pre-GM turbo engines were almost ridiculously overbuilt.)
The more horsepower you force through an engine, transmission, and drivetrain, the faster those components will wear out. All cars are engineered to handle the amount of power the engine produces for a reasonable amount of time. Companies like Toyota and Honda usually being on the longer end of that timescale, and companies like Fiat being on the other end. If an engine is manufactured with a turbo install at the factory, the car will be (hopefully) engineered to handle the additional power that comes with it. However, if you buy a car that is not equipped with a turbo from the factory, you will most likely either need to make upgrades to the vehicle so it can handle the extra power or accept the fact that the vehicle will fail sooner. To answer your question, as long as Toyota manufactures the cars to handle the extra power, which being Toyota they likely will, the vehicle will last just as long as a naturally aspirated one. However, if they use the same engine components, transmission, and drivetrain as before, and then slap a turbo on, it will most certainly fail more quickly.
