It's much closer to the Integra R engine than the newer K20 engines.
The K series was based on the design of the F20C (not F series as there is a F20B that is nowhere near the same as the F20C).
You'll notice the design of the block and head (not in componentry, but in certain measurments, accessory attachment points, the ladder type bearing carrier, the cam carrier, and the roller-rockers).
design-wise, it is dissimilar in every way to the DC2 ITR engine, but it could not be more the similar to the K series.

So, we don't have iVTEC. Let the record show that we have 'digital VTEC.' I bet our system is much simpler and more reliable than any fancy variable valve timing, from Honda or anybody. Outside of a couple of VTEC solenoid failures, I do not recall ever seeing anything in this forum about VTEC problems. That's good enough for me. The transition to VTEC is a bit crude, but that's half the fun. I enjoy the sudden transition in sound level as the solenoid causes the high lift cam followers to kick in.

philosophically yes, design-wise no.

The F20C was the stepping stone or bridge if you will between the "old" gen Honda engines and the newest generation of K series engines. As steven mentioned, featured such as the roller rockers were pioneered in the F20C and then used in the K series motors.
If there was such a thing as an F20C with iVtec (K20C maybe!) would the transition into VTEC be as abrupt? The RSX Type-S has a K20 with iVTEC, and although I've never drivent his particular vehicle, I have heard that the transition into VTEC is noticeable. Any thoughts?
A TSX I drove (K24) didn't display any noticeable "kick" into VTEC when taken to redline.

I picked up a copy of "Honda Tuning Magazine" from the Bookstore the other day. It actually had S2000 info, which is rare for the automotive press. But mostly talked about Mid90s hondas. Still seems like a better choice for Honda people. Though I won't comment on accuracy without a few more visits to the bathroom.

the RSX/integra K20A K20A2 has VTC + a high profile lobe on the exhaust side as well as the intake side. other K20's / K24's (Civic Si, base RSX, CRV, [TSX? please correct me here] ) have only high profile lobe on the intake side as well as VTC. that's why they don't have the noticeable kick when taken to redline. hope this helps.
