12. Fitting a dry turbo

If you’ve had your car’s turbocharger serviced or have bought a replacement or upgraded turbo, don’t fit it unless the part is primed with oil. From the moment the engine fires up, the turbo will begin to spin very fast. If the oil feed pipe is empty and the turbo un-primed, it could take several seconds for vital lubrication to reach the turbo. A lack of lubrication during operation will easily cause damage to both the bearings and the shaft. How to prevent it

Simply pouring oil through a straw into the turbo’s oil inlet hole will get you going but, ideally, once the turbo is fitted, you want to stop the engine from firing up (by unplugging the ECU or a method achieving the same thing), only turning it over until the oil light goes out on your dashboard. You can then start your Porsche in the usual way. That said, it’s recommended you leave the engine idling for around five minutes to allow the oil to warm up before you engage in a test drive.
