Sierra derivatives

[TQ_uk]

Hiya, if its not too much trouble can someone knowledgable about such things (twinturbo?) point me in the direction, (or even better 'sticky' a list! ) of what year/models are 'the best' donors .

Keeping an eye out for something local....

As I understand it I should be looking for a 2.0 Pinto with Type 9, 5 speed box,
possibly with discs on rear as opposed to drums.

The DOHC and CVH don't seem so popular from what I've read
& from Wiki http://en.wikipedia.org/wiki/Ford_Sierra seems a pre '89 2 litre is the one to go for, correct?

Thanks in advance for any pointers
