Had my car a few months then the rear turbo ceramic wheel snaped due to exessive boost Metal hard pipe had worked loose. This scored the cylinders causing lots of blue smoke on the way home.Striped the motor and found scratched oil pump . Marks in valves and seats,scratches down the sides of cambuckets,Cams and bearings scratched. Crank scratched.Hego broken.The block needed metal stiching as it was cracked between the water way and head bolt hole(nothing to do with the turbo problem). Also showing signs of a porus block above the turbo oil pipe fitting.Rebuilt using N1 oil pump First oversize ACL shells rebuilt turbos with steel internals JE Pistons. 500 Miles after build on of the turbos failed. Changed to 2nd hand HKS 2540 50 miles later knocked a end out. Striped the motor crank centre bearing broken up ends worn oil pump marked. Found the crank to have bad wear at the contact area with thrust washer. Sourcing another part at this time.
