99 si's have a longer intake duration. and a tiny bit more lift. I know the longer duration increase overlap a tiny bit. but theoretically these 99 cams should flow more air and yeild more power per RPM.

ALL listed at @ 1mm!
Integra GS-R
Int-230 dur. / 10.6mm lift
Exh-227 dur. / 9.4mm lift

Civic Si '99 Spec
Int-240 dur. / 10.7mm lift
Exh-227 dur. / 9.4mm lift

dude i donno where you got your info..but its wrong.

b16a:
Int 265 duration .412 lift
Exh 267 duration .379 lift

GSR:

Int 274 duration .423 lift
Exh 276 duration .378 lift

Aren't there a couple different "b16a" cam profiles? Could the b16a2 from the Si have a slightly more aggresive profile?

*edit* nevermind, doesn't this look right actually?

Following cam measured with 0mm of lift:
Civic Si(1999 Spec)
Int-265 dur. / 10.5mm lift
Exh-267 dur. / 9.6mm lift

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

From the ClubSi cam guide. Lots of specs. Dunno if they are 100%.

 

Well this thread makes sense now.

 

specs on clubsi are on

 

What RPM do GSR cams make power to?

 

They should make good power from 44k-81k.
