I've seen a bunch of them. It's a 323F. There's also a 3 door version and a GT version with a 2.5L V6... still doesn't seem to put out much power. I've always liked the looks of the 323, even the older ones. The older model is also available as a hatchback turbo 4wd of which there is an even better version called a GTR (might remind you of a Sunny/Pulsar). And ofcourse there's a boring sedan version too.
the gtx posted is a BF chassis, there was also a BG-chassis gtx, like the gtr posted at the bottom. a lot of protege / escort guys use the BP26 (BPT) motor found in the gtx, as it is a direct swap. a friend had a gtr turbo on his BPT-powered escort, it would boil the front tires at 80 in 4th :eek2:
edit: the mazda mx-3 is a closer match to the nx than anything else
