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.
