Thanks for the response Todd. It make sense to me too though especially because of this motor tht was offered to me.

I could use some advise on programming the DME. Do you know of any sources or have you done this before?

For a track/race car you could use a simple rpm switch to control the valve lift since you will be at full throttle most of the time. However, the valve timing on the variocam plus is 40 degrees total vs 25 on the variocam motor, thus you will need custom DME program to account for this along with the minor changes to fuel mapping etc. So no, you are not crazy and this is a good approach for a race car.

It really isn't that hard that hard to integrate the 7.8 DME, just requires the knowledge. It makes sense for Boxsters because you can't buy a 3.6 or 3.8L Boxster. The costs involved really don't make any sense on a 996 as you can just buy a 3.6 or 3.8 996 especially if you are not doing the work yourself and have to pay labour charges on top of the parts cost.

Todd I just blew my 99' 3.4. It's a full race car and I was considering gpoing with a 3.6 as I have access to a just built Koni motor. Since it's a race car and I don't need all the accessories, etc. I'm considering trying it without changing the harness using my cable TB and intake. I would use a programable window switch for the variocam+, and program my ECU on a dyno for fuel mapping, etc. Am I out of my mind?
