I recently bought a 97 GSR. now i really like the Bumpers on the 99' tegs, now is it possible for me to replace my front & rear bumpers? plus, my interiors completely tan. would replacing the entire interior be a difficult task? and by the way, my vtec isn't that great, i mean, i hear it, but i don't feel much of a pull or boost. is it because the car is heavy? i have H/I/E on it so i kinda expected a little more. thanx for help
