(I've been trying Google's Chrome web browser with Comcast

you see this twice, blame Google.)

I don't know about fit, but I think the EPA has laws against 
putting an older engine in a newer car, as it wouldn't meet 
the EPA standards.  A newer engine in an older car is OK 
as long as the newer engine's EPA controls are retained.
(And that may be based on 40 year old knowledge when
people tried to put 1967 unsmogged engines in 1968 runs
like crap cars.)

That said, an ECU from a '98 might work with the '96
engine, and might tell the EPA sniffer what you want 
it to think.
