I purchased the car a few months ago. The engine has done roughly 150000 kms. The engine underwent a full rebuild approximatley 20000kms ago, not because anything was wrong, just to improve performance. The car is currently running 9-10 psi of boost. The car has many modifications, these are what i can remember:
Larger, high flowed turbo (have no idea what type)
Front mounted intercooler
High flow exhaust
Haltec fuel management computer
Boared pistons
worked head
lowered, camber kit
and many more....
I am unsure on the exact specs of the car as much of the work was done by the previous owner, but i should have the data sheet from the previous owner soon and some better pics!!
