Neat.:)

There's no reason that it wouldn't pass a sniffer test, but it would fail
both visual and scanner-type tests.  Visually, the engine *looks* like a
'91-93 engine; you can only put new engines in old cars, not old engines
in new cars.  Secondly, since your car is *supposed* to be OBD-II, the
inspection station will be expecting an OBD-II port under your dash, which
a Classic/early P10 harness will not provide.  Computer doesn't connect,
but even if it would, the scanner looks for OBD-II stuff that simply isn't
on your car or in your ECU.

You'd probably have better luck trying to install a '96 200SX ECU in your
car...I don't know anything about B14 emissions stuff, though...
