i don't know but they are the same as the USA civic SI.
So probably is better to as ask in the SI forum what is the honda civic SI cams specs because they know.

Yes, You are right, part numbers are different.
Here are stock SI cams (info from
http://www.8thcivic.com/forums/cams-int ... input.html)
stock 06 Civic Si cams are
intake big lobe
256 @ .050 - .475" lift
intake small lobe
194 @ .050 - .270" lift
200 @ .050 - .277" lift
exhaust big lobe
246 @ .050 - .424 lift
Exhaust small lobe
184 @ .050 - .260" lift
202 @ .050 - .266" lift
the 09 Civic Si cams are
intake big lobe
252 @ .050 - .483" lift
intake small lobe
190 @ .050 - 289" lift
I forgot to do the other lobe (I will get it done this week)
exhaust big lobe
247 @ .050 - .431" lift
exhaust small lobe
195 @ .050 - .285" lift
same as the intake, I forgot.
But I think K20Z4 has different camshafts than K20Z3...

the FN2 are the
14110-RSP-G00 (intake)
14120-RSP-G00 (exhaust)
I have compare this to the SI 2006 cams in a honda print and the are the same.
Yes probably the same specs and diferent part numbers.
