Yeah actually in Finland there were some "Stockmann turbo" Sierras and Scorpios available from new. They were the 1.3 and 1.6 Pintos turbo'd by the importing firm in the 80's. They weren't really performance cars but still boosted OHC engines available from new.
I myself find the Pinto turbo or in this case "ohcworth" engine appealing because of the widely available parts and knowledge and they have been proven strong and good when done properly.
BTW I love mk2's was actually saving for one before I bought this Sierra but ended up spending all on this.
