no. i don't think there is. actually, i read a post from here by someguy saying that his friend always made 1~2 more hp (tuned) by using ctr intake and gsr exhaust cams together rather than using ctr intake and exhaust cams....who knows...anybody else remember this thread?

Yeah, sometimes I see them on the road and think they look ugly. Thats why I am hesitant to do it.

i think it makes the car look sorta heavier or lower...i dont know what it is, i always liked wings but i bought my car stripped and i got a type r wing and didnt really like the look so i kept it wingless and i really like it with the newer bumper

I don't think you will see\feel any serious gains. The higher duration exhaust cam will be letting out more exhaust gasses but there is not more oxygen getting in since the intake cam is stock so it is basically doing nothing. Do both at once along with adjustable cam gears if you want to see some worthy gains. Also consider an intake manifold

OK, yes there is a difference. Both this thread, and the thread that was linked have a number of inaccuracies regarding these cams. Hopefully these specs will set things straight. This information was taken from Sam Karp's great B-Series Cam Guide posted at ClubSi.

Following Cams Measured at 1mm of lift:

Integra GS-R
Int-274 dur. / 10.7mm lift
Exh-276 dur. / 9.6mm lift

Civic Type-R And Integra Type-R(Integra Type R 2000/01 Spec)
Int-243 dur. / 11.5mm lift
Exh-235 dur. / 10.5mm lift

Integra Type-R(Through 1999 Spec)
Int-240 dur. / 11.5mm lift
Exh-235 dur. / 10.5mm lift
