I have for sale a k14 I have rebuilt. Came from an AAZ engine. Part # is 028 145 703E. Rebuilt with a 360 degree thrust washer and new journal bearings and oil seals. Wastegate functions as it should. Compressor and turbine wheels in good shape. No excessive shaft play.
I was going to use it in a frankenmotor build but plans have changed.
$200 plus shipping.
Pics to follow.
