When was the NG engine intro'd?

[Dwight Varnes <xmxbreed@lancnews.infi.net>]

I know the NG was available in the 87.5 Coupe GT, but when did it make
it's appearance in the standard 5000? And at what point (or was it the
same time) that the injection was changed?
Is there a way to tell what engine is in a car without finding the
stamping on the block itself? I thought there was a tag somewhere.

Please reply personally as I am not currently on the list. Mind the
return address instruction below.
TIA,
