oil everywhere.......hopefully you didn't crack a piston/ring/or ring land. if there's a bunch of oil coming out of the valve cover breather then it'd be a good idea to do a compression test on all the cylinders and make sure you didn't pop your motor.
blowing a turbo seal means smoke billowing out of your exhaust when the car runs...blowing your motor (in this scenario) means excessive crankcase pressure forcing oil out of everywhere it can......which is what it sounds like you did...
a turbo kits one thing.....whether ebay or the most expensive kit in the world....but not being tuned for either, will most assuredly leave you with a blown up motor.....
