If the turbo was not balanced properly the turbo would fail as soon as the car was first driven.
As soon as it pushed through a shaft speed barrier where it would become unstable the turbo would fail.
There has been around 10 failures now out of hundreds and hundreds sold though us and although in their day they were faultless towards the end of us supplying these through Murnane Motors the quality and service which we demanded could not be supported by the main manufacturer without constant supervision by us.
Subsequently that business closed down and was sold (now under new ownership) and deserted what was a very good arrangement which we provided to Skyline owners.
It was a shame and they have not been made for over 9 months now.
