I just looked at a '98 Legacy L for sale. Same colors as my '99 Brighton, same five speed, a few more options, many more miles (170k vs 80k on mine). Under the hood I see different intake boxes and tubing, not sure what else, I didn't have my car for comparison. Why would there be differences under the hood? Would they do a redesign for the last year? Or maybe they scavenged whatever parts they could find for the last year of the 2.2? I suspect this car won't sell quickly at $3600, that's a lot of miles for most buyers in this buyer's market.

99 was only the last year for the EJ22 in the Legacy. The EJ22 marched on in the Impreza till 01.

 

The 97-up EJ22's had solid lifters and bump in CR from 9.5:1 to 9.7:1, making it interference, and the 99-up EJ22's were Phase II, which meant a change in bellhousing mounting, different-flowing heads, and a change in thrust bearing position. (EndWrench Fall 2003)
