I was talking to my friend today who has a turbo supra, older style and he told me to hold the compressor wheel on the turbo when i go to start it for the first time, until it builds oil pressure so i dont burn out the bearings. he said he put oil directly into it and started it and burned it up. and burned another by just starting it. finally someone told him to hold it until oil pressure builds and lubes the bearings and your fine... anyone heard of doing this?
what you do is you unplug your ignition coil on your coil pack and then crank your motor over until you build oil pressure as the car the wont start anyways, then once you have oil pressure, plug it back in and fire her up
yeah i have heard of that one.

Yup. Or pull the fuel pump fuse and relieve fuel system pressure.
For sure actually the turbo i had came with directions to perform that action for that purpose. Crank for 20 seconds with the ignition disconnected to build oil pressure and then let care idle for 45 minutes to break in the turbo.

Now mind you, this might work... After all, at idle the exhaust probably doesn't have enough "oomph" to spin the compressor if you're already holding it still, but after seeing what happened to Bob Norwood's hand after being sucked into a centrifugal blower, I'm really not inclined to put my hand anywhere near a compressor wheel attached to a running motor. Its best just to stick with the nice, safe, pull-the-relay method.

Yea im going with Scarab, hand + turbo on a running engine = bad idea. One dumba$$ in school put his hand over the compressor side of a turbo on a N14 i believe and he lost the tips of 2 fingers. Granted a N14 is alot bigger than a Eco, but its still something you'll never catch me doing.
or just have your friend hold it for you since it was his idea

Best idea yet... I am with Scarab on this one.... Won't find me doing that...

or you can just unplug the coil pack all together

i saw a pic of his turbo haha you can put your hand in it lol, like my friend said, his turbo is probably so big that it hardly spools at idle anyway lol.
couldnt you leave the turbo unbolted from the exhaust but have the oil lines hooked up? it sounds like it would work.
horsepower is the force that determines at what speed you hit the wall, torque is the force that determines how far you take the wall with you after you hit it.
Just unplugging the coils is a great way to wash the cylinder walls too. You need to cut fuel out of the equation also to prevent this. You should never crank your vehicle for that long as you WILL prematurely burn up your starter.

yeah i plan to pull the coil plug, i need to get fuel up to the front anyway, i had the fuel rail off and that needs to fill as well as the lines do. i dont plan to sit there and CRANK AND CRANK. just crank a little, stop for a few, crank a little, stop for a few. And i plan to spray a touch of oil in the cylinder wall too since the car has been sitting since november without oil in the motor at all. i squirted a little bit on the bottom end before i put the oil pan on.
^^^^^^^^^
All very good ideas. Oiling is critical especially when dry that long. Little smoke upon start up is good, means you got oil in her, lol.

All i did was inject oil in the feed side of the turbo before firing it up....reconnect my feed line and start it up...if the car is inside the garage and its warm inside the oil is thin enough to give you adequate o/p in no time...i could see to crank for a few then let sit if you had a mile of feed line under the hood.....but disconnecting injectors and ign. is another option too...
yeah i think ill just disconnect the coil on top. that way it fills the line with fuel and moves some oil around in there too. cant hurt i say. hey phil, you up for another cubs game this year?
