Meanwhile, back on topic ...
Diego,
Priming the turbo on a dry motor (freshly assembled / never run) does require some thought.
I like to get the whole shitaree fully assembled, (engine turbo and all) and then just prior to hanging the t-belt, I'll spin up the oil pump with a cordless drill / socket combo. (I use a 14mm socket, but knowing you, it'll prolly be a 33/64'ths's nut off a Ford that ya got on there /ubbthreads/images/graemlins/fawkd.gif )
Run the drill long enough to make sure everything "sees" oil, but don;t wash out all the engine assembly lube from the rods /mains uneccessarily
On an engine that has been running and has just had a turbo swap, you dont have to get too crazy.
Pull the spark plugs, unplug the cas, and spin it on the starter for ~30 seconds, pause and then repeat twice more.
With the plugs out, there won't be enough air moving past the turbine wheel to spin the turbo fast enough to hurt anything, and since the all the galleys are already full, the turbo will see oil almost immediately
You should be good to put the plugs back in and go at that point, but don't zing the motor, let it settle in at a fast idle for a few moments before tossing any revs at it.
Fix any (and all /ubbthreads/images/graemlins/grin.gif ) oil leaks, and then you can get back to boostin.
