I was wondering if there is any data of how many GSI's 16V were made. In Germany+Vauxhall?
As I am offered 89. model, and I heard once that first 10000 were with CostCast, what's the chance of me being lucky? I know that it is possible to visualy determine if it is, but that car is 150 miles from me so...

Well loosely, the trend seems to be (with respect to the Astra) that the earlier the car the more likely it is to have a Coscast head. So there's a fair chance an '89 model could have one, as it's one of the early ones.

Theres no huge difference in the heads.

Have a look at my guide, here

and you'll be able to tell straight away if its a COSCAST head.
