Rb20 Turbo Swap

[Luke HCR32]

In the process of swapping my leaky factory RB20 turbo for another second hand one in better condition.

What precautions do I need to take to ensure it receives oil pressure when i first start up the motor? I've heard of turbos being damaged in this way.

pull the plugs out and crank the motor until oil pressure come up on the gauge, once thats done re-fit the plugs and go

[Luke HCR32]

As in all the individual spark plugs?

[zebra]

yes

[Luke HCR32]

There's no simpler way to do it i.e. Cutting the power to the plugs further back?

If not that's cool, I've been meaning to do a compression test soon anyway.

you can simply pull the injector fuse...but the engine wont crank hard enough to build oil pressure, with the plugs out there is no compression so the motor spins faster for longer and can build oil pressure.

Ok thanks mate I'll have a crack in the next few days

[gotRICE?]

wouldnt there still be oil in it if its 2nd hand? I would have thought the rule would be for brand new turbos.

When you turn the car off, im guessing most of the oild drains back then. Whats the difference?

[zebra]

Depends on how long its been sitting around

Just put a funnel in where the banjo bolt goes in and fill it up with oil just before running it. It will get enough oil to stop any issues, when they assemble them they would use some sort of grease, they wouldn't ever put the bearings together dry.
