No but,I belive there is a difference in the computer tune it's more
aggresive,and the fuel system is also different and a couple other
things that I forgot.97 was rated at 215hp and the 98 was rated
at 225hp.
the differences were with the exhaust and the fuel system. on the 98, the fuel regulator is built right into the rail, and cannot be removed...i just put a rail from a 97 on mine with a regulator to get around that.
