'89 Mustang turbo?

Thanks Wood! Good article. I think I might order that book at the end of the article. I've heard it before and according to the article, it's true. The motor has to be the same year as the car or newer. Well, my motor is an '87, the car is an '89. How are they gonna tell what year the motor is? The year is stamped on the turbo side of the block, about 2 inches below the deck. Maybe, if I grind off the 87, plus the fact, it's covered by the exhaust manifold and turbo - how in the world would they be able to determine the year of the motor?!! I can just tell them I slapped on a turbo off an '89 Merkur (even though it's an IHI). They can't be that knowledgable! Maybe there's hope, after all! Thanks!
