Forced Induction and Engine Wear

[taracor]

So if forced induction does increase engine wear, how do companies include OEM turbo/superchargers and still have an incredibly reliable engines? Or is the engine built differently?

Also, if that's the case, how would one go about upgrading the engine components on a Yaris to be able to comfortably withstand being boosted? (Or was that what was mentioned about Garm doing?)

oem boosted engines are built more solid and come with lower compression then n/a cars do. and also alot of research and development went into designing the motor and plus to they have alot of years behind them doing this and i mean alot. but upgrade the rods and pistons and change oil earlier then you normally would and run necessary gauges to monitor and dont beat the crap out it everyday and it will be reliable if tuned ight of course

So even a Blitz Supercharger which boosts to a relatively low PSI would decrease engine life? The reason I ask is I've been reading up about other cars and people safely giving them a relatively low boost without building the engine. Granted, the engines I've read about are a bit more performance oriented than the one in the Yaris (I've been looking at 350z's, S2000's, and Civics) but I figured that the stock engine in the Yaris had a level to which it could be safely boosted too, or is my thinking flawed?

blackstone oil analysis is a racers best friend, they'll be able to tell you almost everything about your engine.

some people do enough abuse to their oil after 1 weekend, some can go 3-4 weekends + daily driving before they "need" to change.

it really depends on the setup and oil analysis is a very cheap and good idea, especially if they have a baseline of your car pre-boost. :)

lots of different variables when building a motor, assuming it'd put together right and it's tuned right you still will see less miles out of a built motor than you would a stock one.

good idea is to build it for 250 more horsepower then you plan to have. :)
