Fuct-up-Drifter

Here is the problem

I burned up a single turbo on my 93 drifting at BW raceway in cali
it would smoke like crazy right when I would come off the track and then stop
I would wait around for awhile and then go back out after the track clear off and the same thing would happen
the other rx7 drivers out there agreed that it was a turbo problem
I just got a brand new turbonetics t4 62-1, installed it and everything was great
right when the car started to warm up it started smoking, not like last time it just smokes all the time. I thought it might just be some left over oil in the motor so I took it to the end of my street and back. There is no loss of power and the car idles fine. It just smokes like Cheech and Chong. I am talkin huge smoke. There is some oil leakage around the bottom of the engine on the driver’s side, right by the motor and the tranny but that’s it.
Still have good oil pressure and nothing else seems to be unhappy.
Any ideas why my car looks like Mt. St. Helens?
