Recently I was looking for a good cam set for the application I am currently looking for and found a number of different lists for cam specs. The Japanese standard for measuring cam specs is @1mm which is, unfortunately, different from what some American brands like to measure at. I went through all the specs I had and converted them all to @1mm (except 3 I haven't done yet). This lets you do a much more accurate side-by-side comparison. I know there are a few other brands available (ZEX is one I just didn't put in, although I did know about it). If anyone knows any specs for sure that I have not included, please post and I will update the list!

gotta save this! thanks..!

 

ttt just in case anyone else would like to see

 

yeah i agree with you...

 

Bump Good info for cam comparison

 

1 question: how did you convert .05" lift and duration specs to 1mm (.0394") lift and duration specs? As far as I know, there's no way to reliably do this.

 

 

Not so much convert as do all the dirty work calling various companies. These are all confirmed, the 3 that are not listed were not, and I didn't wanna post (possibly) inaccurate info. Enjoy!

 

one last bump to the top unless anyone else wants to

 

Cool list, thanks

 

 

nice list!

interesting to me to see that the gsr and 99-00 si exhaust cams are the same, learned something new

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

 

does anyone know if specs are different for first gen b16 cams

tia

 

I've been trying to get all the open and closing angles at .050" as well as the lobe centerline angles. I'll try to put up what I have some time later on, but some are pretty hard to come by.

 

bump good info

 

nice info, but what are the crower 401 specs?

 

Crower 401
Int- 249 @ 1mm dur. / 11.38mm lift
Exh-240 @ 1mm dur. / 10.54mm lift

Crower 401T
Int- 240 @ 1mm dur. / 11.81mm lift
Exh-237@ 1mm dur. / 11.30mm lift

 

By chance, did you come across automatic SiR cams ? Alot of ppl are looking to find out the measurements as comparted to the manual ones.

 

so thee 99 si cam is better than a gsr cam? you sure?

Nope...

 

I'm sure this is all on the VTEC lobe... anyone know if the stock cams differ in primary lobe size ?

 

but this post shows the 99 si cam to haver higher lift and duration than a gsr. i think the #s are wrong on that

 

does anyone know if there's any difference between 1st & 2nd gen. B16 cams. I have a B16A3, but my friend is givin me some 99" B16A2 cams. Just wondering if it's worth my time to swap em over.

Does anyone know the if those numbers are correct??? Seems intresting if soo....

 

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
measured with 0mm of lift

ya numbers are wrong....even converted to 1mm of lift the gsr cams have more duration and more lift on the intake side
