Why do we look down on honda's? I mean there are 8 second honda's for christ's sake.
But from a modifying standpoint it's all or nothing.
It's either I/H/E and get 20 more hp, or throw on the JRSC and run 13's with your gsr. It's either a fartcan exhaust, or swap out your D series motor for a Bseries one.
Basically we define a car's appeal to the aftermarket by EASE of modification, not by potential. Because 2000 lb honda hatches obviously have more potential than a 3100 lb wrx.
That being said, I really wish someone would come out with a cheap SC kit for the IS that was <3000. Now that would own.
