Turbo break in time

[scottypimppin]

Ok so I just rebuild my td05h turbo and about to put it back on how many miles should I drive to break in the turbo

None, bolt it on and go.

Sweet can't wait to start boosting again the n/a just doin it for me

I recommend cranking the engine to prime the turbo then letting the engine idle for ten minutes or so while you check for oil and coolant leaks then going out and boosting.

This is another method, but this is a little extreme:

TURBO BREAK-IN

So I should unplug the coil pack n crank it for how long ?

Just unplug the MPI fuse and crank away. Without the fuse, the engine will not inject fuel so it will not start, but the oil pump will turn, creating oil pressure to feed your turbo. Keep in mind that your starter motor has cranking limits. Don't go cranking on it for an extended length of time or you could burn it up. You should see your oil pressure gauge go up as you crank the engine over.

Someone, please correct me if I'm wrong, but unplugging only the coil pack will still allow the injectors to fire and depending on how long you crank, could flood the engine with gasoline and possibly contaminate your oil.

Yes, you are absolutely right in my opinion.

Didn't you say that you never prime the engine after an oil change? Why would you do so after a turbo swap? (besides to check for leaks)

K thanks guys

Why would you need to prime the engine after an oil change?

When you remove the turbo, the oil line is voided. Priming ensures the oil supply line is full of oil and the turbo is ready for when the engine fires.

I normally use assembly lube on my rebuilds in case my customers don't prime their oil supply.
