New Turbo pre-install

I just bought a rebuilt stock turbo for my 1997 Mitsu Eclipse GST and I'm just wondering if I need to bleed the oil or coolant into the turbo or anything like that before I run it.

Unplug the harness off the coilpack. When you have all the fluids in there and filled up, crank the car numerous times. I do 10x when I do my turbo for the first time, but that may be a little over kill. This will get the car cranking, but won't turn over. All the fluids will push through the lines and go where they need to.

ok i just read that on another forum, i guess its called priming the turbo....Well from what i just heard from my dad, he tried starting it up without priming it and it started just fine at idle but then as soon as he was going to test drive it, it started making a really bad noise, like one of the turbine blades in the turbo is hitting against the housing. Any idea what that is?

Not priming the turbo makes the turbo start without it being lubricated. Is this a brand new turbo or used? New turbos have never seen oil in their bearings, which will wear out super quick and cause issues if not lubed up right off the bat. Used turbos usually still have a small bit of oil left in them from whenever, so it won't be as bad. Either way, priming is important.

Pull the filter off the turbo and manually spin the blades and see if anything is hitting. Then start the car and try to listen to where it's coming from... if it's the compressor, the turbine, or the mid section. Also check for oil leaks from the turbo in the intercooler piping.

It's a rebuild. The engine is still pretty hot from earlier, I'll check all of that in the morning and get back to you.
