    Hi guys,

    I'm super paranoid about damaging or wearing out my turbo prematurely. I've been told to warm my car up before hitting boost and to let it cool down. When warming it up I just wait for water temp to reach normal levels :dunno: but how long should I cool it down for?

    I usually just stay off boost for about the last 5-10mins of a drive is that long enough?

    Oil changes every 5000km?

    Warm up as in 2-4 minutes. Then drive it slowly until it reaches normal levels and you can get boost happy (another few minutes at the most).

    As for the cool down, it depends on how long you've been driving. I've always give it a minimum 2 minute cool down for every day driving, and a good 4 minutes if it was a long drive.

    I change my oil about every 3k miles (whats that in metric?) I use synthetic oil also.

    Most modern turbo cars don't need to "cool down" after average driving. I know my STi has a system in which coolant continues to flow through the turbo to keep the oil moving even after the car is shut off. My general rule of thumb is to keep the rpms low/no boost until the car gets to normal operating temperature for a minute or two. I also make sure to take it easy on my tranny as well since the tranny fluid is still cold. After that, I drive like normal. When approaching my destination, I take the last 2-3 miles real easy (low rpms/no boost) and then give the car a good 30 seconds idle. If I have just got done flogging the car, I will leave the car idle for 2-3 minutes as well. I do oil changes every 3500 miles or sooner (depends on how close Auto-X events are approaching) and use Dino oil and plan on switching to Mobil 1 synthetic at 10k.

    Don't boost hard until the car is up to normal operating temperature.

    If you boosted hard before stopping, let the car idle down for about 1-2 minutes. Or buy a turbo timer.

    If you drove easy for a few minutes after boosting, you're fine.

    Run synthetic oil, and change the oil a bit more often than a normal n/a car.

    #1 way to extend the life of the turbo - don't boost unnecessarily.

    The coolant is just another way to cool the center cartridge. It does not keep the oil moving after the car is shut off. "Most" OEM turbos are water cooled because the typical consumer does not let it cool down after a drive and would normally just shut it off immediately. It does help cool down the center somewhat, but the fact remains that the hot oil will eventually cook on the bearing if constantly driven hard and turned off immediately. You need the oil to flow until it cools down.

    you dont need to to warm up it up if 50 degrees or warmer. And its only after beating the piss out of it you should let it "turbo down". I have an Escort LX that I made turbo with a homemade kit. It has an excess of 200,000 mile on it and i beat the hell out of it and it runs and drives great without warming it up or cooling it down. I have an IHI turbo.....the best ever
