I'd recommend not to drive it. I blew mine doing recce for Targa, and had to drive it ~200km home (i was in the middle of bumf**k nowhere, didn't really have a choice) . When I pulled the turbo off, there was oil everywhere through the pipes, but luckily for my the compressor wheels just bent round instead of brake/file. But it's less than ideal to put oil all through your IC and pipework. Also you will struggle to get up any hill, or pull out into traffic.
My Turbo is currently at hypergear getting the smallest highflow avaliable.
