YACT: turbo?

I heard that (well, for heavy trucks and so on) the life of the engine can be "measured" by the fuel consumed: an engine will resist half a million gallons of diesel fuel no matter if you idle it of drive to the floor. A turbo will increase fuel consumption, so the "normal" wear will be increased.
Also, if you put the turbo to increase the maximum RPM, the moving parts of the engine will be forced over the normal functioning regime, causing excessive wear. The wear caused by the increased pressure and forces in the engine (which are also over the engineering specification) also decrease the lifespan

This only applies to mass transit engines, where they are on almost all the time.
Back on topic - a small turbo with relatively low boost should be fine. Just make sure you stay on top of your maintenance, always run the highest grade gas possible, and be responsible with the boost (don't crank it up past the safe limit unless you're running race gas and know what you're doing).
You'll probably also want to upgrade the fuel system (injectors, pump, FPR/FMU).

"properly installed" often involves working with the internals.

If the turbo is not water-cooled, then a turbo-timer is very beneficial. Also, not all turbo setups with automatics hold boost between shifts, so a bov would still be necessary.

fundamental issues with turbo
1. more heat and pressure reduce the life of your engine. some engines have 'room to spare' and some dont, but you should check how well you particular engine does with forced induction.
2. as described above, turbos vibrate your drivetrain in ways it wasnt designed to. i know a guy who upped his turbos boost too much and the weld in the exhaust system just fell apart because of the vibrations
3. turbos spin extremely fast (much greater than 10,000 RPM). this generates a lot of heat and wear/tear. proper cooling helps but you have to idle your car for a few minutes before you turn it off so that the turbo can cool properly. in general turbos have to be rebuilt or seriously overhauled at about 70K miles.
if installed, driven and maintained properly, turbos can be a great way to boost power. they just require extra vigilence and more care.

Three words for you: fuel, ignition, and maintanence. Get those controlled and it'll be reliable.

mighty nice collection of misconceptions....
1) forced induction will upp the compression in the engine, thats why most turbocharged cars have relativley low compression (8.5 to 1 on a DSM if i recall correctly). Turbocharging an NA car raises the compression even more, so it will put more *strain* on the components. However that doesnt tell you much about how long it w ill last. B18 at 4psi will be absolutely safe, just make sure you put premium in it...
2) Turbos dont vibrate anything... complete BS. The compressor and turbine are ballanced and will at most produce a gyro effect taht negligible compared the the weight of the engine. The turbo is BOLTED DOWN to the exhaust manni - please explain how a 10lb turbo would shake a 500lb engine...
3)turbos dont break down afte 70 or XX number of miles. their lifetime is directly related to how the owners took care of em. HEAT is what kills a turbo and makes the shaft wobble and leak oil. If you time your turbo down and use synthetic to minimize the oil gunk, they will last as long as the car.
MY BROTHER IS BUYING ANOTHER DSM WOOO
i figured i'd share, it's gonna be fun playing with the car. It's a 95 tsi FWD (boo), but hes getting a good deal on it and most of the car has been rebuilt.

taking out my ass? What kind of turbo car do you own?
Turbo timers are just marketing BS, that's a FACT. Being that the turbobuick community is generally older experienced car guys, not ONE of them use turbotimers. I've seen countless buicks with 250k on the turbos and still running fine. In fact, I've never heard of someone losing a turbo under 100k. Yeah, oil gaskets will sometimes leak early and need to be replaced but nothing a turbotimer would fix.
And all turbobuicks are just oil cooled, not water! The water just cools down exhaust temps and slows spools and power. Great for that extra nudge of reliability.
And talking about turbododges' of the 80's where you could get ANY dodge car with a turbo, non of those owners where "ricers" who needed timers. In fact, most had no clue what a turbo was and alot of them where lower income or family people. I know of a couple people running >200k on turbos.
And one final example, look at all of the 3/4 ton trucks pulling work trailers/tracters/mowers etc... Non of those guys have turbotimers for the turbodiesels.
So, in other words, like thedarkwolf said, " The true purpose of the turbo timer is the "Look at me I am cool cause I have a turbo timer" feature."

Define "properly". The intercooler and all may not matter if the bottom end can't handle the higher compression. But if you mean beefing up the bottom end of the engine too, then yeah, it should be just fine.

Eli instead of an insult, why don't you show me an example of them saving a turbo?

Actuall, you don't need a BOV unless you are making over 20lbs of boost. I doubt a stock Integra motor could handle 20lbs of boost without blowing up.
