Thanks! That answers pretty much all my questions. So it sounds like the VTC wiring should be taken care of with the rywire conversion harness. Is getting the O2 sensor for closed loop operation just a mater of finding where to wire it in? Can't wait to get this project going!

No, the VTC is control by the 02-04 K-series engine harness. The F20C engine harness will need to be removed and replaced by the 02-04 RSX engine harness.
If i bothered, i could of wired in the o2 sensor plugs but for my purpose a innovative wideband and input logged via the Kpro is enough.
Good luck with your project

Circuit Club Australia Day
I took the car out once more in its naturally aspirated form at Circuit Club track-day. Did a few sessions before handing the keys over to the misses to drive the car. Fellow S2000 customer's also had the opportunity to have a taste of what a K24 feels like in a S2000. They all loved the extra torque and pull out of corners.
Best time was a 1:07.5. Its a 0.5 sec quicker than the F20c in naturally aspirated form. All in all, it wasn't a great improvement from switching over to the K-series but we have a greater platform to work with now. If we persisted with the K-series naturally aspirated, im sure we can get it into the 1:06's with AD08R. The extra torque requires more grip from the tyres but due to class restriction we are keeping with AD08R's
Here are some pictures from the day

Rotrex Supercharged K24 S2000
Fitment of the Rotrex supercharger require slight modification of the subframe in the S2000. This was the only thing that put us off from fitting the rotrex charge from the start of the conversion. After finding some time and with the help from our friends next door, we modified the subframe for the Rotrex clearance
All the original pipe work from the F20c fitted perfectly.
The stock F20c clutch didn't like the extra torque of the K24 supercharged and required replacement. We opted for the clutchmaster FX400 over the other brands. The pedal is nice and light and feels just like OEM
Dyno result of the K24 Supercharged setup wasn't a big surprise for us. Our Time Attack DC2R has a similar set-up so we knew it would make similar due to driveline lost. The comparison against the F20C supercharge was good to see. Unfortunately we couldn't get a final dyno readout with the car breaking traction at high RPM's.

1/4 mile - 12.3@120mph https://www.youtube.com/watch?v=Rv6KdsYFFhk
We were pushing the limits of a stock k24 rods beyond its purpose. The increase rev limit of 8500rpm and the added 20psi wasn't friendly on the stock K24 rods. We are not surprise with the rod breaking is the amount of torque the set-up is making compared to the F20C
We now know the limits of the stock K24 rods for boosted set-ups. A forged bottom end is currently being assembled by the team so we can make similar power more safely.

wiring info
can you give more info on how the wire harness and convertion harness go... just a little more details on the wiring please thank you.
Build Progrss - Headers and Wiring
There was a few option for headers when running a K24 in the S2000. Ballade sport makes K24 swap headers but being RHD, its not 100% certain it will clear the steering rack rod. After using the stock F20c headers on last supercharge setup making over 300kw, we decided to modify the F20c headers to fit the K24 motor.
Next on the list to do list is wiring. I'm using a brand new 02-04 RSX-s engine loom. The AUS spec DC5 engine loom won't be long enough to place the ECU back in the cabin.
Attachment 96032
The 02-04 RSX engine loom is 70% plug in. It still needs some wire to be extended and adapting some of the old F20C plugs
