Detailed cam info?

[InsanityInc]

Does anyone have detailed camshaft information for:

240/248 KA stock cams232/232 KA stock camsJWT camsPDMRacing cams

By detailed, I mean: duration, [email protected], lift, intake opening/closing and exhaust opening/closing.

[:: orion ::]

S13 cams, duration at .050" = 207 / 215

JWT cams: 256 / 256 to be compared to S-chassis cams (275 / 275 as advertised)

PDM has more specs on the website...

What do you mean by this? Are there two different JWT cam types for KAs?

[DjPantsSpecR]

no, he's saying that JWT says its 275/275, but when compared to the Nissan cams, or the way nissan states the duration of their cams, they would technically be 256/256

i know, i was excited too

Sorry that was unclear...

By one way of measuring (Nissan):

S13 = 240/248S14 = 232/232JWT = 256/256

By another way of measuring ( @ .050"):

S13 = 207/215PDM Stage II = 221/231PDM Turbo = 221/221

And finally, advertised duration:

PDM Stage II = 272/278JWT = 275/275

...

Hope that clarifies - Brian

So, theoretically, the PDM cams are also about 256/256ish in "nissan duration"?

That would explain why neither grind has a very substantial effect, to be sure.
