Default Turbo question

Hey guys i just finished rebuilding my 2.0 wrx with a new crank, bearings,gaskets, piston and rings. It had one completely missing rod bearing thats why i rebuilt it, got rid off all the metal shavings inside. My question is, when i went to put the turbo on i noticed the shaft had alot of play (in/out) and up and down ( just bought the car). It will obvuasly need to be rebuilt but i was wondering can i leave the turbo on just to start the car and hear it idle for the first time untill i get the rebuild kit? also i blew air through the oil line to get rid of any metal that could have been in the turbo from the bearing.

In and out play is bad. Td04's are common in the local classified sections.

rebuilding or buying used is about the same price. TD04's typically dont like to be rebuilt. ...they can be but its not common... Something about supply and demand, market shift... better options available...

to to the classified section and find a slightly used td04. I got one with 10k miles for $150 shipped. it's easier and cheaper than new/rebuild/upgrade. of course, this only applies if you're happy with your current numbers.

also, I'm fairly certain you COULD start it with no turbo at all, provided it's for a very brief period or time.

You can find used td04s all the time in the private classifieds, be careful though when making a purchase

As for starting the car with a bad turbo, you can but I wouldn't drive it

yeah you can start it with that turbo on as long as it has no oil shavings and stuff in it. when you make sure of this take your ignition fuse out and crank the car till the oil light goes off to prime the system with oil.
