As most regulars know, my Turbo has been down in Bournemouth for a good many months having its engine rebuilt. The car is a 1989 250bhp Turbo with matching engine and chassis numbers correct for the year and all the usual gizmos for an '89 car (M030, brake ducts etc).
However I have just learnt from Jon Mitchell that all is not what it seems. On close inspection of my turbocharger it turns out that it is in fact a K26/6 from an earlier 220bhp car and not a K26/8 as it should be. Closer inspection of my old head also revealed that it too is from an earlier 220bhp car (there is some difference re oil ways apparently). Looking at the condition of the parts Jon believes that they have been on the car for a very long time and can only guess that maybe the original turbo failed and damaged the head very early in the cars life. At that time there were not many S/H spares around for a 250bhp car so maybe thats why the earlier parts were used.
I am the 4th owner and bought the car from a friend in the club four years ago, and he had owned it for the previous two years. It came with a very full (and I mean full) and complete folder of OPC and Specialist history going back to the day it was first sold. However it just goes to show that with old cars there really could be so many little skeletons hiding in the cupboard.
It does make me feel a little happier about my weedy 282bhp at last years Dyno Day - it only had an ickle turbo []
