If I'm not mistaken, the VTi is SOHC while the SiR is DOHC...

I have the JDM SIR II B16 in my EK. Its got 10:4 compression as opposed to the us versions having 10:2. I dont know if theres any difference in camshafts of not? Vtec kicks in at 5900RPM.
I thought some VTI's had a B16 as well????

UK VTI's come with B16's. Its JDM vti's that come with a D-series. And yes I think there is some difference in cam's between UKDM VTI's and the SIR.

Sorry, I didn't know what DM of Civic we were talking about. I was referring to JDM and PhilippineDM VTi's and SiR's...
