An 06 2.5i or a 98 RS, both stock.
This is a discussion on What's faster... within the Comparison: WRX vs World forums, part of the Community - Meet other Enthusiasts category; An 06 2.5i or a 98 RS, both stock....
they are both slow... but between the 2 I'd take the 2.5.

AFE Filter, ebay catback.
03 RR Evo sold
a quick google search reveals the following specs:
98 RS: 137 hp, 2825 lbs.
06 2.5i: 173 hp, 2972 lbs (sedan/manual transmission)
a little math shows the lbs/hp:
98 RS: 20.62 lbs/hp
06 2.5i: 17.18 lbs/hp
so it looks like, in a straight line, the 06 2.5i would be a bit faster.
my mistake, i read the chart wrong. that was for the engine in the L. the RS does have 165 hp. curb weight was correct.
so that makes the 98 RS 17.12 lbs/hp. so they're quite close.
FYI i got my info here: Subaru Impreza Archives: 1997-1998
I was running 15.5 in my 98. My brother has a 06 and i think i would've taken him.

The "who's faster" question should also be applied to handling, where I believe the lighter, more nimble GC8 would stand out.
